Low concentrations of fruit acids (less than 20%) can be used for maintenance, while high concentrations (20%-70%) can be used for peels. Concentrations of fruit acids vary in dermatological science: at very low concentrations, fruit acids have only a moisturizing effect. At slightly higher concentrations, it has an exfoliating effect, breaking down cellular bonds in the stratum corneum and stimulating the skin's metabolism. In higher concentrations, its destructive power is greater, the effect reaches the dermal tissue, can be used to do chemical peels. Generally speaking, the higher the concentration, the more effective it is, but the chance of side effects also increases.

Acne treatment: acne, pimples, blackheads, pustules, enlarged pores .

Spot lightening treatment: pigmentation, brown spots, acne marks, dull and lusterless skin.

Anti-aging treatment: skin aging and dull, fine wrinkles, keratin accumulation. The effect of fruit acid peeling on the skin: Fruit acid peeling can make the skin peeling, removing the aging epidermis, so that the skin looks delicate and smooth. This exfoliation is mainly due to the fact that fruit acids reduce the adhesion between keratinocytes. However, the long-term effect of fruit acids on the epidermis and dermis requires low concentrations of fruit acids for continuous maintenance and multiple peels to show up.

The exfoliating effect of fruit acids diminishes as the skin adapts to them. The result is that the stratum corneum becomes regular and the epidermal cell layer thickens.

The acidity (pH) of a fruit acid determines its effect on the skin and its ability to alter the skin's acidity. The ideal acidity of fruit acids is between 2.8 and 4.8, which is most effective for epidermal rejuvenation.
