It’s that time of year again—aka Amazon’s Prime Big Deal Days. Amazon’s fall sale, better known as October Prime Day, has arrived with hundreds of thousands of major discounts for you to shop. With two days to take advantage of deals, I’m using the event as an excuse to restock my beauty arsenal for the new season and pick up some early holiday gifts. 

You’ll find highly-rated customer favorites on sale across all categories including makeup, skincare, and hair, as well as plenty of Byrdie-approved K-beauty products. Since the sale ends on October 8, I decided to make things a little easier for you by rounding up some of the best beauty deals the sale has to offer, with picks from brands like T3, Medicube, K18, and more.
