Scarring can occur if the mole removal treatment is deep, damages the dermis, or if there is an infection after the treatment due to improper care. Scars after mole removal can be reduced or eliminated through medication, photoelectric treatment and surgery. 1. Medication: For patients with mild scar symptoms and in the early stage of recovery, topical silicone gel and vitamin E can be used to inhibit the growth of scars, reduce hyperpigmentation and improve the visual effect. 2. Photoelectric treatment: If the scar is more obvious after removing the mole, then you can help eliminate the scar after removing the mole through fractional laser, picosecond laser and other aesthetic treatments, the principle of which is to irradiate the scar site through the laser, through the stimulation of skin dermal collagen fiber proliferation, coagulation of the scar at the superficial capillaries, and other mechanisms to promote the repair of local scars. 3. Surgical treatment: If the scar proliferation or atrophy is more obvious after mole removal, and there are manifestations such as protruding from the surface of the skin, serious depression, scar atrophy, etc., and the shape of the scar is stable, at this time, the scar can be directly removed by local surgical excision, but considering the invasive way of surgery, it is recommended that fine surgery be performed by a plastic surgeon in order to avoid the formation of scars again after the surgery. In addition, in order to achieve better results, patients should pay attention to regulating their dietary patterns at the same time as the above treatments, such as: eating a light diet, avoiding spicy and stimulating foods, quitting smoking and drinking, and eating more fruits and vegetables rich in vitamins and fiber, and so on. It should be noted that the above treatments should be carried out by specialists in regular medical institutions to avoid the occurrence of adverse reactions.
