Scars are usually self-repairing after stitches are removed. The time to repair varies according to individual differences, with some scars taking about 1-2 months to repair, but some scars may take more than 3 months, or even more than 6 months. When the scars are obvious after the stitches are removed, topical medications can be used to slow down the scars to a certain extent. Mucopolysaccharide polysulfate cream can be applied topically, twice a day, with gentle massage or light rubbing for 1-2 minutes after application. In addition, topical application of sodium heparin allantoin cream can also be used to effectively slow down the proliferation of collagen tissue, thus slowing down the occurrence of scar tissue.
