The most direct and simple way to replenish water is to take a bottle of emulsion with a nozzle with you and replenish water in time. However, it should be noted that it is not recommended to spray water directly on the face except for some beauty sprays. Because the water sprayed on the face cannot be preserved by the stratum corneum, it will accelerate the evaporation of water and make the skin drier and drier. Toner is the most effective and direct product to replenish skin moisture. When in use, first use oil-absorbing paper to absorb excess grease on the face, and then use emulsion to spray on the face. Spray once every 3 to 4 hours to keep the cells in the stratum corneum in a normal state. Eye cream or eye gel can be used to reduce the appearance of dry lines.
