COSRX
Advanced Snail 96 Mucin Power Essence – 100 ml
This is the essence that put COSRX on the map — and for good reason. It's a lightweight, fast-absorbing formula that hydrates, soothes, and repairs without irritation . Snail mucin (snail secretion filtrate) is rich in growth factors, antioxidants, hyaluronic acid, and glycoproteins — all known for hydration, protection, and skin repair . Small clinical studies have shown it helps hydrate dry skin, strengthen the skin barrier, stimulate collagen production, and heal wounds . Think of it as a drink of water for your skin. It won't exfoliate or brighten aggressively — but it will make every product after it work better.
