Once a leg scar appears, it can not be completely removed, and can be improved by photoelectric treatment, drug treatment, surgical treatment and other ways. 1. Photoelectricity treatment: at present, the commonly used clinical methods include: pulsed laser dye used in the early stage of scarring, occlusion of local capillaries to inhibit scar proliferation; carbon dioxide fractional laser, erbium laser, etc. to improve the appearance of scarring through the mechanism of stripping and stimulating local collagen regeneration. 2. Medication: Silicone gel and allantoin gel can be used to inhibit scar proliferation at the early stage of scarring, and glucocorticosteroid can be injected into the scar, such as Triamcinolone acetonide injection for the treatment of scarring. Vitamin A can also be used for treatment. 3. Surgery: If the above treatment is ineffective and the scar affects the appearance and function, surgery can be carried out, and after surgery, combined with X-ray radiation therapy is needed. If you have scars on your legs that need to be removed, do not use drugs on your own, you need to go to a regular medical institution as soon as possible to avoid causing serious complications.
