When Cosrx skincare products first popped up on my TikTok "For You" page, I was admittedly skeptical about their effectiveness. The idea of dapping up my face with a sticky, snail mucin-infused serum left me completely perplexed and frankly, a little disturbed—that is, until I finally tried the viral Snail Mucin Power Repairing Essence for myself.

Fast-forward to today, with multiple Cosrx bestsellers incorporated into my daily skin regimen, and my complexion has never looked healthier or more vibrant. I'm also far from alone in my experience; Cosrx's cult-favorite essence currently boasts over 63,000 five-star ratings on Amazon's site, and the formula was bought by more than 70,000 people last month alone (NBD). Best of all, the most popular Cosrx products (including the viral snail essence) are currently discounted at Amazon's Big Spring Sale for up to 38% off.

Ahead, I rounded up the best Cosrx deals at Amazon's spring event, including the Cosrx Snail Mucin Glass Hydrogel Face Masks that I swear by for achieving TikTok's "glass skin" trend. Be sure to check out the spring discounts for yourself and consider adding a product or two to your own beauty arsenal.
