Scar removal methods for lips include medication, surgery, physical therapy, etc. Usually, scars with small area that do not affect the appearance and health can be left untreated. 1. Medication: Glucocorticoids, such as Triamcinolone acetonide injection, can be injected into the scar lesions to induce vasoconstriction of the scars and inhibit the proliferation of fibrous tissues, thus softening the scar tissues; topical retinoic acid preparations, such as retinoic acid ointment, etc., can also be used, but not to be smeared to the mucous membranes of the lips. 2. Physical therapy: For early scars, carbon dioxide fractional laser, erbium laser and other photoelectric treatment can be taken to improve the appearance of scars by stripping and promoting collagen rearrangement. 3. Surgery: If the above two methods cannot remove the scars and the patient still has the will to improve, surgery can be taken. It is recommended that patients go to the dermatology department of a regular hospital, choose the appropriate treatment under the guidance of the doctor, and strictly follow the doctor’s instructions to use medication, do not blindly self-medication, so as not to cause adverse consequences.
