Snail mucin is a natural substance secreted by snails and is increasingly used as an active ingredient in skincare products. It is rich in nutrients, including proteins, vitamins, minerals, and hyaluronic acid, which can help maintain hydration and improve skin texture. Snail mucin may contribute to the regeneration of damaged skin cells, reduce mild inflammation, even out skin tone, and enhance skin elasticity. Its popularity in the beauty world has grown thanks to Korean cosmetics, and it is often found in serums, emulsions, sheet masks, and other skincare products.
