There are many ways to lighten scars, and the treatment methods are different for scars of different severity and different periods. For example, in the early stage of scar formation, you can generally use medication to lighten scars, such as vitamin E cream, aloe vera gel cream, recombinant bovine growth factor cream, scar removal spirit, etc., which can play a certain therapeutic effect. If the scars are serious and more than 3 months old, medication will not have a good effect at this time, and surgical treatment or laser treatment can be considered to improve the scars. If you are a scar patient, it is not easy to intervene with surgery and other treatments to avoid aggravating the symptoms, you can consider local closed treatment methods, such as closed injection of glucocorticoids, which can make the scars shrink.
