A hydrogel mask is a skincare product designed to hydrate and nourish the skin. Made from a gel-like material, these masks are infused with various beneficial ingredients such as hyaluronic acid, vitamins, and plant extracts. They adhere closely to the skin, allowing for better absorption of the active ingredients. Typically used for a short period, hydrogel masks provide a cooling sensation and can help improve skin texture and appearance. They are often used in beauty routines for a quick boost of moisture and are suitable for various skin types, including sensitive skin.
