For scars after sebaceous cyst surgery, if it is just after the surgery and waiting for the stitches to be removed, appropriate topical medication or physical therapy can be applied to slow down the possibility of scar formation to the maximum extent. Topical topical medications such as cumene cream ointment or topical sodium heparin allantoin cream can promote the absorption of local scar tissue and the repair of the original tissue. If there is an inflammatory reaction, physical therapy, such as red and blue light irradiation, can also be used to treat the scar. If a scar has formed, glucocorticoids such as Depo-Provera can also be injected to flatten the scar.
