Fruit acid peeling, i.e., using highly concentrated fruit acids to exfoliate the skin, promote the shedding of the aging keratin layer, accelerate the renewal rate of keratinocytes and a few upper epidermal cells, and promote the proliferation of elastic fibers in the dermis. Fruit acid peeling is effective for superficial acne scars and can also improve enlarged pores, but it takes several treatments to eliminate acne scars. The skin condition after fruit acid peeling is very fragile, if you do not pay attention to hydration, it is likely to cause dry skin, and there may be localized tingling and burning sensation, or itchy, red, tight facial skin, and in severe cases, there may be a small area of scarring. If you do not pay attention to sun protection, after ultraviolet radiation, local skin pigmentation and other phenomena may occur. Especially for the candidates with thin skin stratum corneum, it will make the skin texture more sensitive after use. During the treatment, patients may experience a tingling sensation, and slight redness and pain after treatment. If there is crusting, it will fall off on its own within 7 days, but it should never be picked by hand as it may leave scars. Suitable conditions for fruit acid peels include acne, enlarged pores, aging skin, melasma and other pigment-increasing skin diseases, as well as superficial scarring, periorbital keratosis and amyloid skin lesions. Therefore, the use of fruit acid peels depends on the skin condition, do not try blindly, and do not choose a high concentration of fruit acids.
