The principle of fruit acid peeling is to use high-concentration fruit acid to cause the aging cells on the surface of the skin to fall off, promote the aging stratum corneum to fall off, accelerate the renewal rate of keratinocytes and a small number of upper epidermal cells, and promote the elasticity of the dermis. Fiber hyperplasia has a good effect on superficial acne scars and can also improve enlarged pores. (It is corrosive to a certain extent, but relatively safe)

Note: It is not recommended for people with allergic skin, sensitive skin, and younger people.

Fruit acid is a general term for a variety of chemical substances. Because most of them can be found in natural fruits, they are called fruit acids, including glycolic acid extracted from sugar cane. Lactic acid is extracted from yogurt, tartaric acid is obtained from wine, malic acid is obtained from apples, and citric acid is obtained from citrus fruits. The chemical structure of fruit acids contains hydroxyl acids, so they are abbreviated as AHA. AHA was discovered by American doctors more than ten years ago. It can exfoliate the epidermis, stimulate dermal metabolism, and grow tender skin. Doctors use AHA to restore skin health to untreated acne and pimples.

The currently known fruit acids can be divided into three major categories:

α-Hydroxy acid: It is a weak acid, also known as A. It is most commonly used as AHA. Glycolic acid and lactic acid;

β-hydroxy acid: plant acid, also known as B argan acid BHA, which is salicylic acid;

α&β-hydroxy acid : Malic acid, citric acid.

BHA is more effective than AHA in reducing blackheads and preventing acne. In addition, BHA is stronger than AHA in terms of stability, irritation and sensitivity. The concentration of BHA used for skin peeling is 20%-30%.

The effects of different fruit acids on the skin:

① Low concentration of fruit acids (less than 10%): Fruit acids can reduce the cohesion between epidermal keratinocytes and can remove aging cuticles. Improve rough, dull, and condition skin texture.

② Medium concentration of fruit acid (10%-30%): The effect of fruit acid can reach the dermal tissue, and can treat acne, lighten dark spots, smooth wrinkles, etc.

③ High-concentration fruit acid (more than 30%): It has strong penetrating power, which can peel off aging cuticles at once, accelerating the effect of removing spots and wrinkles. However, high-concentration fruit acids are skin-removing properties, so it is best to seek treatment from a professional doctor.

There are more than a dozen types of fruit acid peels. In fact, there is a lot of knowledge, which kind of fruit acid should be used, how long it takes to apply the fruit acid, how much % of the fruit acid should be used, and how much fruit acid should be used every time. Everyone is different.

Furthermore, fruit acid peels also have certain risks, such as pigmentation, bacterial infection, and common complications after chemical peels, which are mostly caused by excessive sun exposure in the scab removal area. Therefore, avoid the sun, use external sunscreen, and take vitamin C and vitamin E orally. Or superficial bacterial infection or recurrence of herpes simplex.
