There are several treatment options for facial scars, and depending on the time of scar formation and location of the patient, there are differences in the scar removal methods chosen, and the specific situation needs to be analyzed. Usually, medication is preferred for scar removal. In case medication is not effective, physical therapy and surgery can also be chosen. I. Drug treatment: 1. Topical drugs: If the scar formation on the patient’s face is short and the symptoms are mild and not obvious, consider topical drug topical treatment. Under the guidance of professional doctors, drugs such as silicone gel and mucopolysaccharide polysulfate can be used. 2. Local injection: If the scar formation time is long and the scar proliferation is obvious, when the effect of topical drugs is not obvious, you can visit the hospital and apply local drug injection for treatment, including tretinoin, compound betamethasone injection, etc. Second, physical therapy: 1. Fractional laser: the scar tissue is ground and flattened by photothermal reaction. Usually, laser therapy has a good therapeutic effect on both hyperplastic and atrophic scar; 2. Ultrasonic therapy: Promotes the dispersion of collagen fibers and has a certain softening effect on hyperplastic scar tissue; 3. Cryotherapy: Uses the low temperature of liquid nitrogen to freeze and destroy the hyperplastic scar tissue for the purpose of treatment; 4. Pressure therapy: Applicable to both hyperplastic and atrophic scar patients. Using bandages to apply local pressure to the scar to enhance the blood flow rate in the body and promote cell metabolism, thus achieving the purpose of treating the scar. Surgical excision: Surgical excision can be considered for proliferative scar tissue that seriously affects the function and appearance of the body, but there is a risk of postoperative recurrence.
