How often is it appropriate to exfoliate the face? A proper stratum corneum also has a certain protective effect on the skin, which can resist UV rays and bacteria damage to the skin, but the stratum corneum should not be too thick, too thick will affect the normal metabolism of the skin. The cycle of skin cell metabolism is generally 28 days. If you take care of your skin regularly and remove dead skin every time you take care of it, the rate of skin metabolism will be accelerated and the cycle will be shortened accordingly. The face is rich in nerves and blood vessels, sensitive to external stimulation, some beauticians are too heavy and forceful, so the skin is easily strained, resulting in wrinkles and pigmentation, accelerating skin aging becomes inevitable. Therefore, too diligent skin care brought about by the skin’s temporary beautiful effect, is the price of premature aging of the skin. Facial exfoliation is appropriate once a month.
