As a shopping editor, I've covered a lot of Amazon sales in my lifetime—big spring sales, Black Friday sales and yes, even the sale-to-end-all-sales: Prime Day. With years of extensive deal-hunting experience, I'm rarely surprised by any Amazon discounts, no matter how steep they may be—that is until today, when I saw that select Cosrx skincare products are up to 52% off at Prime Day 2025.

I'm not exaggerating when I say that Amazon's Prime Day Cosrx deals are so massive, so unheard of, they literally stopped me in my tracks and had me reaching for my nearest credit card. Cosrx is regarded as one of today's most popular K-beauty brands, with an inventory of dewy, TikTok-viral products that are designed for a variety of skin types and rely on unique (read: arguably weird) ingredients like snail mucin to remedy even the peskiest skin concerns.

The cult-favorite Cosrx Snail Mucin Essence remains the skincare brand's most coveted product, but there are tons of other customer-favorites, like the Cosrx Snail Mucin Face Moisturizer and Cosrx Acne Pimple Patch. All of these, plus so many other K-beauty staples, are on sale for a limited time this week.

Why are Cosrx products so popular?

Cosrx is regarded as one of today's most popular K-beauty brands, with a cult following that includes avid TikTok shoppers (like myself), beauty gurus and even celebrities. Shoppers love Cosrx's wide selection of hypoallergenic skincare products, namely because they're designed to work across a variety of skin types and address several key skin concerns—like pigmentation, dark spots, dullness and even acne breakouts. Despite their popularity, these skincare products still remain relatively affordable—with most Cosrx solutions costing less than $40.
