Not only are scars, infections, and erythema uncommon, but post-inflammatory hyperpigmentation, which is common in the East, is also less common after peels than other types of chemical peels or dermabrasion. In addition, it is not as troublesome as other types of chemical peels or dermabrasion, so it is a procedure worth promoting. Peels generally require multiple treatments to achieve optimal results, especially for dark spots, keratosis, scars, and wrinkles. Each peel is usually performed at two to four week intervals, and the duration or concentration of fruit acids in the skin varies from person to person. The side effects of fruit acid peels are also directly related to the post-peel care. The post-operative care of a fruit acid peel is very simple, the patient only needs to rub the ointment or nutritional cream prescribed by the physician on time for about one to three days, and do a good job of sun protection. Patients can go to work and school normally after the procedure, and resume daily skin care and makeup after about one to two weeks. It is currently believed that the use of fruit acids or A-acid creams before and after surgery can enhance and maintain the effects of the peel. However, to avoid too much irritation, it is not advisable to use vitamin A creams for one week before and after the procedure. So how does fruit acid peeling work? The effect of fruit acid peeling can be seen from the epidermis and dermis respectively: when fruit acid peeling acts on the epidermis, it reduces the polymerization force between keratinocytes, accelerates the shedding of aging keratinocytes, enhances the speed of epithelial cell metabolism, promotes skin renewal, and also makes the epithelial cells more neatly arranged, so the stratum corneum becomes smooth and delicate.
