After removing the mole, it will definitely leave a scar. Because nevus is a benign tumor of human body, it still has a great influence on local skin. After laser removal of moles, dark pigment deposits will be left. So diluting the pigment is the key to leaving traces. Generally speaking, attention should be paid to the maintenance of the wound surface after mole removal. At first, try not to get wet, and the scab needs to fall off naturally, so don't expose the scab artificially, otherwise it will easily enlarge the wound surface and cause infection. In addition, vitamin C can be taken orally, which can dilute pigment and accelerate wound healing. Don't do anything to grind the skin, it will only make the skin worse and worse, and normal maintenance is the key.
