**COSRX Snail Mucin** is a popular skincare product known for its hydrating, repairing, and soothing properties. The key ingredient is snail secretion filtrate, which is rich in nutrients like hyaluronic acid, glycoproteins, and glycolic acid. These components help to improve skin texture, boost moisture levels, promote healing, and support collagen production, making it beneficial for repairing damaged skin, fading acne scars, and reducing fine lines. The product is lightweight, non-greasy, and easily absorbed, making it suitable for all skin types, especially for sensitive or acne-prone skin. It’s often praised for its ability to restore a dewy, plump complexion while calming irritated skin.
