Oily and dry skin are well differentiated, but there is also a skin that is a combination of skin, oily and dry skin. The oil area of the mixed skin is generally on the forehead and the nose, and the rest is dry. Therefore, when doing skin care, mixed skin should pay special attention. Whether you are oily skin, dry skin or mixed skin, these three skins are unhealthy skin. The common feature is that the skin is very water-deficient. Replenishment is the key to caring for these different skin types. When you use skin care products, don't forget to drink more water every day. This is also the way to help your skin hydrate.
