There are ways to remove pigmented moles without leaving scars. To remove pigmented moles, they are mainly removed by high power ionization, laser cautery or by surgery. However, no matter which method has the probability of leaving scars, you can choose to apply human-like collagen repair silicone gel after the treatment, after the local skin has healed and without painful touching. This repair silicone gel can effectively restore the orderly growth of disordered fibroblasts, which can reduce the probability of leaving scars to a certain extent. In addition, after the scars have formed, you can choose to use carbon dioxide fractional laser, which can effectively prevent the formation of depressed scars and can flatten the skin, and can also be combined with pulsed dye laser, which can effectively make the raised scars fade and become flat with the skin, so as to leave no scars.
