1. Main functions of essence: essence usually contains high concentration of active ingredients, aiming at specific skin problems, such as moisturizing, whitening, anti-aging, etc., to provide deep nourishment and repair for the skin.
2. Function of lotion: lotion is mainly used to lock water and moisturize. It can form a protective film on the skin surface to prevent water loss and keep the skin moist. Lotion can also help the skin better absorb the skin care products applied before.
3. Whether to use lotion: after using essence, it is generally recommended to continue to use lotion. Because although essence is rich in nutrition, it may lack sufficient moisturizing ingredients to lock water. Lotion can supplement this and make the skin care effect more lasting. Of course, if your skin is very greasy, or the essence used has enough moisture and contains enough moisturizing ingredients, you can also consider omitting lotion. But generally speaking, in order to maintain the water oil balance and the best state of the skin, it is recommended to continue to use lotion after the use of essence.
