Dented scars can be repaired by laser treatment, hyaluronic acid injection, mechanical abrasion, and autologous fat filling surgery. 1. Laser treatment: Laser treatment can promote the growth of subcutaneous collagen in the depressed area, making the depression filled, so as to achieve the effect of scar filling and skin repair. 2. Hyaluronic acid injection: Hyaluronic acid has the effect of filling the skin, which is widely used in the clinic, and you can choose local injection of hyaluronic acid to treat depressed scars, with good therapeutic effect. 3. Mechanical grinding: the epidermis of the depressed scar and the epidermis of the surrounding skin are ground off by mechanical grinding, and the self-repair mechanism of the body is utilized to make the contrast between the depressed scar and the surrounding skin smaller and the boundary become blurred. 4. Autologous fat filling surgery: For serious depressed scars, the body’s own fat tissue can be surgically filled into the depressed area to improve the symptoms of depression. Patients are advised to visit regular hospitals and choose the best treatment plan under the guidance of doctors to achieve satisfactory treatment results.
