The principle of fruit acid peeling is to apply a high concentration of fruit acids to exfoliate aging skin, which in turn accelerates the rate of renewal of keratinocytes and some upper epidermal cells, thereby improving skin problems. After long-term use, it can promote the synthesis of collagen and hyaluronic acid, which has the effect of improving skin tone and rejuvenation; it can also promote the release of more hyaluronic acid from the dermis and enhance the skin’s ability to retain water. However, if the procedure is not performed properly or the patient does not pay attention to post-operative care, the following risks may occur: 1. Skin burns: mainly manifested as skin congestion, edema, flushing, burning pain, running water and scaling. If these symptoms are not effectively controlled, infection may occur, or even pus and scarring; scar formation, abnormal sensation; 2, allergy: manifested as skin erythema, itching, etc., requiring timely medical treatment; 3, hyperpigmentation: some patients may have hyperpigmentation, herpes simplex recurrence, etc.; 4, skin thinning, especially dermal thinning. Therefore, in order to avoid the above, patients should pay attention to the use of conventional medical skin care products, moisturizing and sun protection in accordance with medical advice. Usually patients will feel discomfort 1-2 days after surgery, but be careful not to pick off the scabs with your hands when the skin is in a crusty state.
