Shallow depressed scars, i.e. clinically speaking shallow depressed scars, need to be repaired by medication, physical therapy or surgery under the guidance of specialized doctors. 1. Medication: In the early stage of shallow depressed scar formation, apply recombinant human epidermal growth factor gel to promote local tissue regeneration to help the epidermis recover as prescribed by the doctor. 2. Physical therapy: Fractional carbon dioxide laser and other photoelectric treatments can peel off the surface layer and stimulate collagen proliferation to improve depressed scarring. Combined with topical application of growth factor gel can increase the clinical effect. 3. Surgery: For those who are not well treated with conservative treatment and the scar affects the appearance, the scar can also be completely excised by surgery, loosening the adhesion of the tissue and then cosmetically sutured; or transplanted with autologous fat filler in the depressed area to improve the purpose of the sunken scar. In conclusion, for patients with shallow depressed scars, it is recommended to go to a regular hospital in time and follow the doctor’s advice to choose the appropriate treatment to repair.
