Replenishing water: With the increase of age, the self-repairing ability of skin declines, so we should pay more attention to the basic moisturizing class from the beginning of makeup water. In addition to cleaning the skin for the second time, the lotion can also adjust the acid-base balance of the skin for the first time and eliminate the skin tension after cleansing. Soaking the stratum corneum fully with make-up water can not only replenish the required moisture for the skin, but also promote the penetration of subsequent products and assist the comprehensive penetration and absorption of high-nutrient components. And drink enough water every day, which is good for skin metabolism. Supplementary nutrition: eat more fruits and vegetables to provide necessary nutrition for the skin. Reasonable work and rest: rest on time and keep regular living habits, so as to better protect the skin.
