many reasons\u2014they can be the after-effects of acne or brought on by hormonal conditions like melasma, for example. Regardless of the cause, treating them is likely your first priority when you see them appear. If you want to take action, consider incorporating a vitamin C product into your skincare routine. According to dermatologists, this powerhouse ingredient can help fade dark spots and offers a host of other skincare benefits. <strong>Ahead, find out everything you need to know about using vitamin C for dark spots.<\/strong><\/p>\n<div id=\"mntl-sc-block_4-0\" class=\"comp mntl-sc-block beauty-sc-block-callout--meetourexpert beauty-sc-block-callout mntl-sc-block-callout mntl-block theme-meetourexpert\" data-tracking-id=\"mntl-sc-block-callout\" data-tracking-container=\"true\">\n<p id=\"mntl-sc-block-callout-heading_2-0\" class=\"comp mntl-sc-block-callout-heading mntl-text-block\">Meet the Experts<\/p>\n<div id=\"mntl-sc-block-callout-body_2-0\" class=\"comp mntl-sc-block-callout-body mntl-text-block\">\n<ul>\n<li>Purvisha Patel, MD, is a Memphis-based board-certified dermatologist and founder of\u00a0Advanced Dermatology &amp; Skin Cancer Associates and founder of\u00a0Visha Skincare.<\/li>\n<li>Deeptej Singh, MD, is a board-certified dermatologist and founder of Sandia Dermatology.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h2 id=\"mntl-sc-block_5-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What Is Vitamin C? <\/span><\/h2>\n<p id=\"mntl-sc-block_6-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C is a powerful antioxidant derived from natural sources like citrus fruits (think: oranges) and is often produced synthetically in different skincare products, such as serums, moisturizers, toners, and cleansers. The ingredient protects the skin from collagen breakdown and neutralizes damage caused by free radicals. The latter is significant as we are constantly exposed to air, sunlight (UV radiation), and pollutants, which can generate skin-aging free radicals. Because of these properties, Patel says vitamin C &#8220;helps decrease skin breakdown and discoloration, resulting in an overall [more radiant effect].&#8221;\n<\/p>\n<h2 id=\"mntl-sc-block_8-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> The Benefits of Vitamin C for Dark Spots <\/span><\/h2>\n<p id=\"mntl-sc-block_9-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can help reduce the appearance of dark spots and hyperpigmentation. This is because vitamin C down-regulates an enzyme called tyrosinase that&#8217;s involved in melanin production. &#8220;By reducing melanin production in specific areas, those areas can lighten, addressing the concern of dark spots effectively,&#8221; Singh says.\n<\/p>\n<p id=\"mntl-sc-block_11-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> While you may notice your dark spots becoming less noticeable after using skincare products with vitamin C, Patel points out that &#8220;it&#8217;s not a hero ingredient for hyperpigmentation.&#8221; If you&#8217;re aiming to treat dark spots, she says vitamin C works better when the formula features other skin tone-evening ingredients like kojic acid and licorice.\n<\/p>\n<h2 id=\"mntl-sc-block_13-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> How to Use Vitamin C for Dark Spots\u00a0 <\/span><\/h2>\n<h3 id=\"mntl-sc-block_14-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Choose the Right Product Format <\/span><\/h3>\n<p id=\"mntl-sc-block_15-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The pure form of vitamin C, also known as L-absorbic acid, can be found in many formats skincare\u2014from serums to cleansers. However, while many types of products are available, the specific formulation makes a big difference when it comes to treating dark spots. This is for a few reasons. The skin&#8217;s outermost layer, which is called the stratum corneum, is naturally resistant to water-soluble molecules like vitamin C, Singh explains. Therefore, the product must be able to penetrate the outer layer of the skin for the vitamin C to be effective.\n<\/p>\n<p id=\"mntl-sc-block_17-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Patel specifically recommends using a serum. &#8220;It is better that the vitamin C is delivered to the skin in a serum because vitamin C is a water-soluble molecule, meaning it will best traverse the outer layer to the dermis in a water-based vehicle like a serum,&#8221; Patel says. &#8220;The water-soluble vitamin C is more powerful than the fat-soluble variant.&#8221;\n<\/p>\n<p id=\"mntl-sc-block_19-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> However, if you have sensitive skin, Patel says esterified vitamin C products may be less irritating. They&#8217;re fat soluble and may be slightly less effective, but can be a better option if your skin is prone to irritation.\n<\/p>\n<h3 id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Adhere to a Consistent Schedule <\/span><\/h3>\n<p id=\"mntl-sc-block_22-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are a lot of different recommendations around vitamin C use\u2014particularly whether it should be used in the morning or at night and how frequently. Patel says you can use vitamin C serum daily and should apply it to clean dry skin after cleansing and prior to SPF.\n<\/p>\n<h3 id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Combine Your Vitamin C With the Right Products <\/span><\/h3>\n<p id=\"mntl-sc-block_25-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can be used with other skincare ingredients and products to treat dark spots. To treat dark spots, Singh suggests combining your vitamin C serum with moisturizing vitamin E and applying this pairing twice daily. &#8220;This combination is safe and can be tailored depending on the cause of the dark spots,&#8221; he says. Singh also suggests using vitamin C with tranexamic acid for dark spots related to melasma.<\/p>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are some ingredients you&#8217;ll also want to be cautious about while using vitamin C. Patel says you&#8217;ll want to avoid using vitamin C with certain exfoliating ingredients and acids, like retinol and alpha-hydroxy acids, Using these ingredients with vitamin C can cause irritation; mainly if they&#8217;re used together every day. If you apply vitamin C in the morning, Patel suggests using these other ingredients in the evening.<\/p>\n<h2 id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Safety Considerations <\/span><\/h2>\n<p id=\"mntl-sc-block_30-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C is safe for most skin types, but some people may experience irritation. &#8220;If you notice your skin gets too dry or starts peeling after using [vitamin C], then you may be allergic to an ingredient within the serum, or the concentration within may be too high,&#8221; Patel says. &#8220;The strongest form is the alcohol form, [which] can be irritating. Switching to the fat-soluble milder form can be helpful.&#8221;\u00a0\n<\/p>\n<p id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> It&#8217;s best to stick to products with a vitamin C concentration between 10 and 20%. Research shows that products with a concentration of vitamin C above 20% may be more likely to cause irritation.<\/p>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Another important point to remember is that vitamin C is an unstable ingredient. It can easily degrade, oxidize, and lose its beneficial antioxidant properties when exposed to light, air, and heat. This is why it&#8217;s important to use vitamin C skincare products packaged in opaque, airtight containers and store them somewhere dark and cool. If your vitamin C product starts to turn brown or reddish, it may have begun to oxidize and need to be replaced.\n<\/p>\n<h2 id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> The Final Takeaway <\/span><\/h2>\n<p id=\"mntl-sc-block_37-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Dermatologists regularly recommend vitamin C to treat dark spots on the skin. As a powerful antioxidant, this common skincare ingredient can help reduce free radical damage and inhibit melanin production in targeted areas, decreasing the appearance of hyperpigmentation in turn. If you&#8217;re considering adding a vitamin C product to your routine, look for concentrations between 10 and 20%, as this range is regarded to be most effective and non-irritating.\n<\/p>\n<\/div>\n<div id=\"citation-sources_1-0\" class=\"comp citation-sources mntl-article-sources mntl-expandable-block u-article-styles\" data-scroll-offset=\"70\">\n<div class=\"loc toggle-content\">\n<div id=\"mntl-article-sources__wrapper_1-0\" class=\"comp mntl-article-sources__wrapper mntl-block\" data-click-tracked=\"true\"><span id=\"mntl-article-sources__heading_1-0\" class=\"comp mntl-article-sources__heading mntl-text-block\">Article Sources<\/span><\/div>\n<\/div>\n<div class=\"loc expandable-content\">\n<div id=\"citation-sources__text_1-0\" class=\"comp citation-sources__text mntl-text-block\">Byrdie takes every opportunity to use high-quality sources, including peer-reviewed studies, to support the facts within our articles.

Regardless of the cause, treating them is likely your first priority when you see them appear. If you want to take action, consider incorporating a vitamin C product into your skincare routine. According to dermatologists, this powerhouse ingredient can help fade dark spots and offers a host of other skincare benefits. <strong>Ahead, find out everything you need to know about using vitamin C for dark spots.<\/strong><\/p>\n<div id=\"mntl-sc-block_4-0\" class=\"comp mntl-sc-block beauty-sc-block-callout--meetourexpert beauty-sc-block-callout mntl-sc-block-callout mntl-block theme-meetourexpert\" data-tracking-id=\"mntl-sc-block-callout\" data-tracking-container=\"true\">\n<p id=\"mntl-sc-block-callout-heading_2-0\" class=\"comp mntl-sc-block-callout-heading mntl-text-block\">Meet the Experts<\/p>\n<div id=\"mntl-sc-block-callout-body_2-0\" class=\"comp mntl-sc-block-callout-body mntl-text-block\">\n<ul>\n<li>Purvisha Patel, MD, is a Memphis-based board-certified dermatologist and founder of\u00a0Advanced Dermatology &amp; Skin Cancer Associates and founder of\u00a0Visha Skincare.<\/li>\n<li>Deeptej Singh, MD, is a board-certified dermatologist and founder of Sandia Dermatology.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<h2 id=\"mntl-sc-block_5-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> What Is Vitamin C? <\/span><\/h2>\n<p id=\"mntl-sc-block_6-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C is a powerful antioxidant derived from natural sources like citrus fruits (think: oranges) and is often produced synthetically in different skincare products, such as serums, moisturizers, toners, and cleansers. The ingredient protects the skin from collagen breakdown and neutralizes damage caused by free radicals. The latter is significant as we are constantly exposed to air, sunlight (UV radiation), and pollutants, which can generate skin-aging free radicals. Because of these properties, Patel says vitamin C &#8220;helps decrease skin breakdown and discoloration, resulting in an overall [more radiant effect].&#8221;\n<\/p>\n<h2 id=\"mntl-sc-block_8-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> The Benefits of Vitamin C for Dark Spots <\/span><\/h2>\n<p id=\"mntl-sc-block_9-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can help reduce the appearance of dark spots and hyperpigmentation. This is because vitamin C down-regulates an enzyme called tyrosinase that&#8217;s involved in melanin production. &#8220;By reducing melanin production in specific areas, those areas can lighten, addressing the concern of dark spots effectively,&#8221; Singh says.\n<\/p>\n<p id=\"mntl-sc-block_11-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> While you may notice your dark spots becoming less noticeable after using skincare products with vitamin C, Patel points out that &#8220;it&#8217;s not a hero ingredient for hyperpigmentation.&#8221; If you&#8217;re aiming to treat dark spots, she says vitamin C works better when the formula features other skin tone-evening ingredients like kojic acid and licorice.\n<\/p>\n<h2 id=\"mntl-sc-block_13-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> How to Use Vitamin C for Dark Spots\u00a0 <\/span><\/h2>\n<h3 id=\"mntl-sc-block_14-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Choose the Right Product Format <\/span><\/h3>\n<p id=\"mntl-sc-block_15-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The pure form of vitamin C, also known as L-absorbic acid, can be found in many formats skincare\u2014from serums to cleansers. However, while many types of products are available, the specific formulation makes a big difference when it comes to treating dark spots. This is for a few reasons. The skin&#8217;s outermost layer, which is called the stratum corneum, is naturally resistant to water-soluble molecules like vitamin C, Singh explains. Therefore, the product must be able to penetrate the outer layer of the skin for the vitamin C to be effective.\n<\/p>\n<p id=\"mntl-sc-block_17-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Patel specifically recommends using a serum. &#8220;It is better that the vitamin C is delivered to the skin in a serum because vitamin C is a water-soluble molecule, meaning it will best traverse the outer layer to the dermis in a water-based vehicle like a serum,&#8221; Patel says. &#8220;The water-soluble vitamin C is more powerful than the fat-soluble variant.&#8221;\n<\/p>\n<p id=\"mntl-sc-block_19-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> However, if you have sensitive skin, Patel says esterified vitamin C products may be less irritating. They&#8217;re fat soluble and may be slightly less effective, but can be a better option if your skin is prone to irritation.\n<\/p>\n<h3 id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Adhere to a Consistent Schedule <\/span><\/h3>\n<p id=\"mntl-sc-block_22-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are a lot of different recommendations around vitamin C use\u2014particularly whether it should be used in the morning or at night and how frequently. Patel says you can use vitamin C serum daily and should apply it to clean dry skin after cleansing and prior to SPF.\n<\/p>\n<h3 id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Combine Your Vitamin C With the Right Products <\/span><\/h3>\n<p id=\"mntl-sc-block_25-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can be used with other skincare ingredients and products to treat dark spots. To treat dark spots, Singh suggests combining your vitamin C serum with moisturizing vitamin E and applying this pairing twice daily. &#8220;This combination is safe and can be tailored depending on the cause of the dark spots,&#8221; he says. Singh also suggests using vitamin C with tranexamic acid for dark spots related to melasma.<\/p>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are some ingredients you&#8217;ll also want to be cautious about while using vitamin C. Patel says you&#8217;ll want to avoid using vitamin C with certain exfoliating ingredients and acids, like retinol and alpha-hydroxy acids, Using these ingredients with vitamin C can cause irritation; mainly if they&#8217;re used together every day. If you apply vitamin C in the morning, Patel suggests using these other ingredients in the evening.<\/p>\n<h2 id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Safety Considerations <\/span><\/h2>\n<p id=\"mntl-sc-block_30-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C is safe for most skin types, but some people may experience irritation. &#8220;If you notice your skin gets too dry or starts peeling after using [vitamin C], then you may be allergic to an ingredient within the serum, or the concentration within may be too high,&#8221; Patel says. &#8220;The strongest form is the alcohol form, [which] can be irritating. Switching to the fat-soluble milder form can be helpful.&#8221;\u00a0\n<\/p>\n<p id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> It&#8217;s best to stick to products with a vitamin C concentration between 10 and 20%. Research shows that products with a concentration of vitamin C above 20% may be more likely to cause irritation.<\/p>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Another important point to remember is that vitamin C is an unstable ingredient. It can easily degrade, oxidize, and lose its beneficial antioxidant properties when exposed to light, air, and heat. This is why it&#8217;s important to use vitamin C skincare products packaged in opaque, airtight containers and store them somewhere dark and cool.

The ingredient protects the skin from collagen breakdown and neutralizes damage caused by free radicals. The latter is significant as we are constantly exposed to air, sunlight (UV radiation), and pollutants, which can generate skin-aging free radicals. Because of these properties, Patel says vitamin C &#8220;helps decrease skin breakdown and discoloration, resulting in an overall [more radiant effect].&#8221;\n<\/p>\n<h2 id=\"mntl-sc-block_8-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> The Benefits of Vitamin C for Dark Spots <\/span><\/h2>\n<p id=\"mntl-sc-block_9-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can help reduce the appearance of dark spots and hyperpigmentation. This is because vitamin C down-regulates an enzyme called tyrosinase that&#8217;s involved in melanin production. &#8220;By reducing melanin production in specific areas, those areas can lighten, addressing the concern of dark spots effectively,&#8221; Singh says.\n<\/p>\n<p id=\"mntl-sc-block_11-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> While you may notice your dark spots becoming less noticeable after using skincare products with vitamin C, Patel points out that &#8220;it&#8217;s not a hero ingredient for hyperpigmentation.&#8221; If you&#8217;re aiming to treat dark spots, she says vitamin C works better when the formula features other skin tone-evening ingredients like kojic acid and licorice.\n<\/p>\n<h2 id=\"mntl-sc-block_13-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> How to Use Vitamin C for Dark Spots\u00a0 <\/span><\/h2>\n<h3 id=\"mntl-sc-block_14-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Choose the Right Product Format <\/span><\/h3>\n<p id=\"mntl-sc-block_15-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The pure form of vitamin C, also known as L-absorbic acid, can be found in many formats skincare\u2014from serums to cleansers. However, while many types of products are available, the specific formulation makes a big difference when it comes to treating dark spots. This is for a few reasons. The skin&#8217;s outermost layer, which is called the stratum corneum, is naturally resistant to water-soluble molecules like vitamin C, Singh explains. Therefore, the product must be able to penetrate the outer layer of the skin for the vitamin C to be effective.\n<\/p>\n<p id=\"mntl-sc-block_17-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Patel specifically recommends using a serum. &#8220;It is better that the vitamin C is delivered to the skin in a serum because vitamin C is a water-soluble molecule, meaning it will best traverse the outer layer to the dermis in a water-based vehicle like a serum,&#8221; Patel says. &#8220;The water-soluble vitamin C is more powerful than the fat-soluble variant.&#8221;\n<\/p>\n<p id=\"mntl-sc-block_19-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> However, if you have sensitive skin, Patel says esterified vitamin C products may be less irritating. They&#8217;re fat soluble and may be slightly less effective, but can be a better option if your skin is prone to irritation.\n<\/p>\n<h3 id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Adhere to a Consistent Schedule <\/span><\/h3>\n<p id=\"mntl-sc-block_22-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are a lot of different recommendations around vitamin C use\u2014particularly whether it should be used in the morning or at night and how frequently. Patel says you can use vitamin C serum daily and should apply it to clean dry skin after cleansing and prior to SPF.\n<\/p>\n<h3 id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Combine Your Vitamin C With the Right Products <\/span><\/h3>\n<p id=\"mntl-sc-block_25-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can be used with other skincare ingredients and products to treat dark spots. To treat dark spots, Singh suggests combining your vitamin C serum with moisturizing vitamin E and applying this pairing twice daily. &#8220;This combination is safe and can be tailored depending on the cause of the dark spots,&#8221; he says. Singh also suggests using vitamin C with tranexamic acid for dark spots related to melasma.<\/p>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are some ingredients you&#8217;ll also want to be cautious about while using vitamin C. Patel says you&#8217;ll want to avoid using vitamin C with certain exfoliating ingredients and acids, like retinol and alpha-hydroxy acids, Using these ingredients with vitamin C can cause irritation; mainly if they&#8217;re used together every day. If you apply vitamin C in the morning, Patel suggests using these other ingredients in the evening.<\/p>\n<h2 id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Safety Considerations <\/span><\/h2>\n<p id=\"mntl-sc-block_30-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C is safe for most skin types, but some people may experience irritation. &#8220;If you notice your skin gets too dry or starts peeling after using [vitamin C], then you may be allergic to an ingredient within the serum, or the concentration within may be too high,&#8221; Patel says. &#8220;The strongest form is the alcohol form, [which] can be irritating. Switching to the fat-soluble milder form can be helpful.&#8221;\u00a0\n<\/p>\n<p id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> It&#8217;s best to stick to products with a vitamin C concentration between 10 and 20%. Research shows that products with a concentration of vitamin C above 20% may be more likely to cause irritation.<\/p>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Another important point to remember is that vitamin C is an unstable ingredient. It can easily degrade, oxidize, and lose its beneficial antioxidant properties when exposed to light, air, and heat. This is why it&#8217;s important to use vitamin C skincare products packaged in opaque, airtight containers and store them somewhere dark and cool. If your vitamin C product starts to turn brown or reddish, it may have begun to oxidize and need to be replaced.\n<\/p>\n<h2 id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> The Final Takeaway <\/span><\/h2>\n<p id=\"mntl-sc-block_37-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Dermatologists regularly recommend vitamin C to treat dark spots on the skin.

This is because vitamin C down-regulates an enzyme called tyrosinase that&#8217;s involved in melanin production. &#8220;By reducing melanin production in specific areas, those areas can lighten, addressing the concern of dark spots effectively,&#8221; Singh says.\n<\/p>\n<p id=\"mntl-sc-block_11-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> While you may notice your dark spots becoming less noticeable after using skincare products with vitamin C, Patel points out that &#8220;it&#8217;s not a hero ingredient for hyperpigmentation.&#8221; If you&#8217;re aiming to treat dark spots, she says vitamin C works better when the formula features other skin tone-evening ingredients like kojic acid and licorice.\n<\/p>\n<h2 id=\"mntl-sc-block_13-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> How to Use Vitamin C for Dark Spots\u00a0 <\/span><\/h2>\n<h3 id=\"mntl-sc-block_14-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Choose the Right Product Format <\/span><\/h3>\n<p id=\"mntl-sc-block_15-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> The pure form of vitamin C, also known as L-absorbic acid, can be found in many formats skincare\u2014from serums to cleansers. However, while many types of products are available, the specific formulation makes a big difference when it comes to treating dark spots. This is for a few reasons. The skin&#8217;s outermost layer, which is called the stratum corneum, is naturally resistant to water-soluble molecules like vitamin C, Singh explains. Therefore, the product must be able to penetrate the outer layer of the skin for the vitamin C to be effective.\n<\/p>\n<p id=\"mntl-sc-block_17-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Patel specifically recommends using a serum. &#8220;It is better that the vitamin C is delivered to the skin in a serum because vitamin C is a water-soluble molecule, meaning it will best traverse the outer layer to the dermis in a water-based vehicle like a serum,&#8221; Patel says. &#8220;The water-soluble vitamin C is more powerful than the fat-soluble variant.&#8221;\n<\/p>\n<p id=\"mntl-sc-block_19-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> However, if you have sensitive skin, Patel says esterified vitamin C products may be less irritating. They&#8217;re fat soluble and may be slightly less effective, but can be a better option if your skin is prone to irritation.\n<\/p>\n<h3 id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Adhere to a Consistent Schedule <\/span><\/h3>\n<p id=\"mntl-sc-block_22-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are a lot of different recommendations around vitamin C use\u2014particularly whether it should be used in the morning or at night and how frequently. Patel says you can use vitamin C serum daily and should apply it to clean dry skin after cleansing and prior to SPF.\n<\/p>\n<h3 id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block beauty-sc-block-subheading mntl-sc-block-subheading\"><span class=\"mntl-sc-block-subheading__text\"> Combine Your Vitamin C With the Right Products <\/span><\/h3>\n<p id=\"mntl-sc-block_25-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C can be used with other skincare ingredients and products to treat dark spots. To treat dark spots, Singh suggests combining your vitamin C serum with moisturizing vitamin E and applying this pairing twice daily. &#8220;This combination is safe and can be tailored depending on the cause of the dark spots,&#8221; he says. Singh also suggests using vitamin C with tranexamic acid for dark spots related to melasma.<\/p>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> There are some ingredients you&#8217;ll also want to be cautious about while using vitamin C. Patel says you&#8217;ll want to avoid using vitamin C with certain exfoliating ingredients and acids, like retinol and alpha-hydroxy acids, Using these ingredients with vitamin C can cause irritation; mainly if they&#8217;re used together every day. If you apply vitamin C in the morning, Patel suggests using these other ingredients in the evening.<\/p>\n<h2 id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> Safety Considerations <\/span><\/h2>\n<p id=\"mntl-sc-block_30-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Vitamin C is safe for most skin types, but some people may experience irritation. &#8220;If you notice your skin gets too dry or starts peeling after using [vitamin C], then you may be allergic to an ingredient within the serum, or the concentration within may be too high,&#8221; Patel says. &#8220;The strongest form is the alcohol form, [which] can be irritating. Switching to the fat-soluble milder form can be helpful.&#8221;\u00a0\n<\/p>\n<p id=\"mntl-sc-block_32-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> It&#8217;s best to stick to products with a vitamin C concentration between 10 and 20%. Research shows that products with a concentration of vitamin C above 20% may be more likely to cause irritation.<\/p>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Another important point to remember is that vitamin C is an unstable ingredient. It can easily degrade, oxidize, and lose its beneficial antioxidant properties when exposed to light, air, and heat. This is why it&#8217;s important to use vitamin C skincare products packaged in opaque, airtight containers and store them somewhere dark and cool. If your vitamin C product starts to turn brown or reddish, it may have begun to oxidize and need to be replaced.\n<\/p>\n<h2 id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block beauty-sc-block-heading mntl-sc-block-heading\"><span class=\"mntl-sc-block-heading__text text-title-300\"> The Final Takeaway <\/span><\/h2>\n<p id=\"mntl-sc-block_37-0\" class=\"comp mntl-sc-block beauty-sc-block-html mntl-sc-block-html\"> Dermatologists regularly recommend vitamin C to treat dark spots on the skin. As a powerful antioxidant, this common skincare ingredient can help reduce free radical damage and inhibit melanin production in targeted areas, decreasing the appearance of hyperpigmentation in turn. If you&#8217;re considering adding a vitamin C product to your routine, look for concentrations between 10 and 20%, as this range is regarded to be most effective and non-irritating.\n<\/p>\n<\/div>\n<p> Source URL: https:\/\/www.byrdie.com\/vitamin-c-for-dark-spots-11878960<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Yes, Vitamin C Can Help Reduce Dark Spots\u2014Here&#8217;s the Derm-Approved Way to Make it Work For You By Beth Krietsch Beth Krietsch Beth Krietsch is a health and food writer with a Masters&#8217;s Degree in Public Health Nutrition.
