The main difference between medical beauty hydrating mask and general hydrating mask lies in the registration number. Medical beauty hydrating mask is close to the middle of skin care products and drugs, and belongs to the medical skin care level. Generally, it is the size of mechanical font, and the general hydrating mask is the size of cosmetic font. The product with mechanical font size is more strict in production and manufacture, contains no spices and additives, and has a single component, which reduces the sensitization rate and alleviates the repair, so the safety factor is much higher than that of the general hydrating mask, and is more suitable for the application of sensitive skin, acne muscles and other problems.
