Raised scars, generally due to proliferative scarring left after the healing of trauma, can choose topical drugs, laser therapy, local closure, surgical excision treatment. 1. Topical medication: silicone products and onion extract products can inhibit scar proliferation, and should be standardized and used for a long time in the early stage of scar formation. 2. Laser treatment: carbon dioxide fractional laser or erbium laser with stripping effect can be chosen to stimulate the regeneration and rearrangement of collagen through laser photothermal effect, and at the same time, part of the scar tissue can be stripped off to improve the appearance of the scar. 3. Local closed treatment: local injection of glucocorticoid, lidocaine, pentafluorouracil, etc. into the keloid scar can promote the atrophy of keloid scar tissue. 4. If scar proliferation significantly affects the appearance or function, surgical excision can be considered, followed by hypotonic cosmetic suture, and standardized postoperative anti-scar treatment to reduce the probability of scar re-proliferative. If you are willing to treat, you should go to the regular hospital in time to avoid blind treatment, which may cause adverse consequences.
