The pits after mole spotting, i.e. depressed scar, can be partially improved through local tissue self-repair, and can be treated with medication and physical therapy if necessary. 1. Self-repair of local tissues: Normally, human skin has self-repair function, just after mole spotting, due to the lack of local tissues, it will leave pits, at this time, local collagen, elastin and other tissues will grow and repair the pits, and the repair process lasts about 2-3 months. 2. Medication: If the patient’s local tissue repair ability is limited, then recombinant human epidermal growth factor gel, polysulfonic acid mucopolysaccharide cream and so on can be used externally to promote the regeneration of local tissues and promote the repair of depressed scar. 3. Physical therapy: If the scar is old and cannot be repaired by the above two methods, then carbon dioxide laser or erbium laser can be used to stimulate the regeneration of subcutaneous collagen in the depressed area to fill the pits and improve the symptoms. It is recommended that patients go to regular hospitals according to their own situation, follow the doctor’s instructions to standardize the treatment, and strictly follow the doctor’s instructions to use medication, not blindly self-medication.
