Snail mucin is a secretion left by snails as they travel along surfaces, it helps protect them from environmental irritants and repair injuries. These same properties are what make it effective for human skin, as mucin is packed full of glycolic acid, allantoin, zinc and anti-inflammatory vitamins, all of which help improve overall skin health.
Snail mucin helps moisturize, soothe irritation and boost collagen production in the skin, as well as keep irritants out of your skin in the first place. It is one of the most popular ingredients in Korean beauty regimens and has shown excellent results for millions of users.
