Scars generally refer to keloid scars, and fractional lasers have some effect on white keloid scars, but the effect may not be significant. White keloid scars are generally due to skin damage to the deep dermis, which leads to loss of pigmentation after healing. Clinically, fractional laser has some effect on early white keloid scars with loss of pigmentation, but its effect may not be great. Fractional laser is a kind of laser that generates laser based on photo-thermal effect and divides the laser into several beams. Using the laser to act on the skin of the affected area can promote the regeneration of skin pigment cells and stimulate the islands of pigment cells that may be present in the scar in a scattered manner to proliferate to the surrounding area, so as to improve the situation of pigment loss. Fractional laser treatment is an option for people with white scarring of the skin, but they need to visit a regular hospital and cooperate with the doctor for a standardized procedure.
