Discover the COSRX Advanced Snail Mucin Glass Glow Hydrogel Mask, a hydrogel facial mask designed to deliver an intense glow and flawlessly smooth texture with a glass-skin finish from the very first application. At the heart of this formula is snail secretion filtrate (mucin), an ingredient renowned for its ability to deeply hydrate, soothe irritation, and enhance skin elasticity. Its effects are amplified by low-molecular-weight collagen (200Da) and adenosine, which together strengthen the skin’s structure and counteract loss of firmness. For added radiance and an even complexion, the formula combines niacinamide with gluconolactone (PHA) to gently promote cell renewal. To instantly restore comfort and protect the skin barrier, the mask features an intensive complex of 5 types of hyaluronic acid, ceramides, panthenol, betaine, and allantoin, which saturate the skin with moisture and reduce redness. Crafted from a solidified essence, the mask conforms perfectly to facial contours and turns transparent as the active ingredients penetrate the skin. This product is the ideal solution for dehydrated, dull skin with fine lines or rough, uneven texture. Benefits Visible glow and smoothing effect Improves moisture levels and maintains tissue hydration Supports skin firmness and elasticity while reducing the appearance of fine lines Quickly soothes irritation and discomfort of reactive skin Helps even out skin tone and correct a dull complexion Enhances smoothness and visibly refines rough skin texture
