There are many ways to remove scars. The specific method depends on the size of the scar, whether it is concave or proliferative. If the area of the scar is small, just slightly higher than the skin or equal to the normal skin, the affected area can be rubbed with mucopolysaccharide polysulfonate cream and heparin sodium gel to promote local blood circulation and help the scar heal. If the area of sunken scar is small, wipe the affected area with growth factor gel to promote epithelial cell proliferation, so that the sunken scar disappears. The medical treatment effect of large or prominent scars is not good. It is recommended to use laser polishing or hormone sealing in hospital to shrink them and remove them. If the area of the sunken scar is large, inject collagen or fat into the deep part of the sunken scar to fill it. No matter what kind of scar it is, do not eat spicy and irritant food during treatment, and prevent ultraviolet radiation when going out to prevent these factors from affecting recovery.
