1.Basic care: cleansing – hydration – moisturizing – sunscreen With the development of modern biotechnology, it is proved that the cause of dry skin is the decline of the skin’s water-locking function, and the ingredient that plays the function of water-locking in the skin is called moisturizing factor (biologically there is called hyaluronic acid HA). The hyaluronic acid in the human body is synthesized by the body itself through the intake of food rich in mucopolysaccharides. Hyaluronic acid decreases with age, and it is slowly broken down and consumed when exposed to ultraviolet light from computers and heat.
