How not to leave scars after scabbing needs to be based on the degree of damage to the wound after scarring, the patient’s personal constitution and the presence of other pathological problems to choose the appropriate treatment measures: I. Degree of damage: 1. Damage to the dermis: If the dermis has been injured, it is more difficult to not leave scars at this time. However, you can also try to apply scar lightening ointment under the guidance of a doctor, such as compound heparin sodium allantoin gel or cumene cream ointment. If the result is not good, you can also try to use laser therapy; 2. Damage to the epidermis: This condition usually does not leave scars, but there may be local pigmentation with healing, which can return to normal by itself through a period of time, but the degree of deposition and the speed of fading is also related to the individual’s constitution. During the recovery period, patients can also use silicone gel or mucopolysaccharide cream to help accelerate the fading of scars. Second, personal constitution: the possibility of not leaving scars after scabbing is smaller for people with scars, which can be removed through plastic and cosmetic surgery. After the surgery, local injection treatment with drugs such as tretinoin is given to prevent hyperplasia, and radiation therapy can also be given within 24 hours of the day of surgery. Third, there are other pathological problems: if the wound healing is slow will increase the possibility of scarring, you need to check whether there is anemia or lack of vitamin B. You can supplement a diet rich in iron, folic acid or vitamin B12. In addition, to minimize scarring, pay attention to the diet during the wound recovery period, consume high-protein and easy-to-digest food, and eat less spicy and irritating food, such as chili, onion and ginger, to avoid itching, redness and swelling of the wound.
