What method is the right one to treat the depressed scar on upper lip? (photo)

Scar revision and percutaneous scar release will work well to reduce the appearance of your lip scar.

Concerned about depressed scar - re-excision, meticulous closure and dermabrasion should help. The scar is oriented relatively well with the wrinkles that we all eventually develop around the mouth. It is widened and somewhat depressed. If it doesn't particularly bother you, I would recommend leaving it alone. If it bothers you significantly, you should wait at least 12 months following the injury to pursue any treatment. The best option to improve this scar would be simple re-excision, eliminating tension on the wound and meticulous closure. Dermabrasion at 6 weeks in the office can then help the scar blend earlier. All of this can be performed in the office setting with local anesthesia.Stephen Weber MD, FACS

Treating a deprressed scar involves both filling the depression and surface of the scar to make it less noticable. I would recommend a combination of subcision with a Fractionated CO2 laser treatment called Deep FX. There will be some bruising and healing over a week and you may require 2-3 treatments for a best result. But the treatment should be extremely effective.
