Scars, or keloids, cannot be completely removed once they appear, and there is no most effective way to do so. There are a number of measures that can be taken to improve the appearance of the scar. The best treatment options for keloid scars are different at different times and need to be taken in different ways depending on the individual’s condition, which mainly include medication, laser treatment and surgery. 1. Medication: Mucopolysaccharides polysulfate cream, cumquat cream and other medications have the effect of inhibiting the proliferation of keloid scars, and their use in the early stage of keloid scarring can help to soften and inhibit keloid scars. Local injection of glucocorticoid into the scar can inhibit the growth of the scar and can reduce the scar, commonly used drugs such as Triamcinolone acetonide. 2. Laser treatment: Fractional laser, erbium laser, plasma and so on are common in the clinic, which can cause thermal damage to the scar tissue, so as to promote the structural rearrangement of the scar tissue to improve the appearance of the scar. 3. Surgery: For some large keloid scars that are not well treated by medication and laser therapy, surgical reshaping can be done according to the individual’s condition. For people with keloid scarring, it should be disabled. Newborn keloid scars are in the keloid proliferation stage and can be improved with topical medications and laser treatments, whereas for old keloid scars, which are more stable in appearance, they can be improved with intra-keloidal injections of medications, laser treatments, and surgical treatments. As the best treatment options for different scars are different, the specific treatment options should be chosen after visiting a regular medical institution and having an interview with a specialist.
