Laser treatments can improve white scars, which are generally referred to as loss of pigmentation remaining after the lesion has healed, with fractional CO2 lasers. Fractional CO2 laser restores normal pigmentation by generating multiple areas of tiny thermal damage, causing the surrounding normal epidermal and dermal cells to migrate to the damaged area and produce filler repairs, as well as stimulating the formation of new collagen. Topical growth factor gels can be used in combination to promote the restoration of local normal skin tissue. The efficacy of laser treatment of white scars is limited, if you want to completely restore the color need to use skin grafting, cosmetic tattooing, surgical excision repair and other methods. It is recommended to go to the plastic surgery department or dermatology department of regular hospitals for consultation and treatment according to medical advice.
