It is due to the use of vinegar essence and facial application to stimulate the skin and cause local skin inflammation. It is suggested that some lincomycin ointment or erythromycin ointment should be used externally. Anti-inflammatory treatment generally does not leave scars, but most of them will have pigmentation. If there is pigmentation after the inflammation subsides, most of it will gradually subside.

Can also be used: cucumber skin is cut into thin pieces and applied to the face twice a day or rubbed with aloe juice to help restore skin color.
