Two: Modern people often slow down their metabolism due to factors such as poor contact with external environmental conditions, unbalanced diet, abnormal work and rest, staying up late, smoking, drinking, and mood. Abnormal metabolism prevents keratinocytes from falling off naturally and accumulating on the surface thickly, resulting in rough and dull skin. The skin care products they apply are often blocked by this thick barrier and cannot be absorbed by the living cells below. Therefore, it is necessary to prevent keratin thickening. The surface layer of skin is metabolized once a week, and too much old waste keratin accumulates on the skin, which will cause skin burden. Therefore, exfoliation is used to remove the dead horniness on the skin surface and let the skin breathe again. It is best not to use ointment. Everything that can exfoliate and change the skin contains strong acid of fruit acid or heavy metal of lead and mercury, which is very harmful to the skin itself and makes the skin completely lose its ability of self-protection and metabolism. Love beauty begins with skin care products, adjusting sleep and diet. Although the effect is a little slow, it is absolutely safe.
