It seems that there are only sunken scars in your photos, but no hypertrophic scars. Recessed scars can be treated with dot matrix laser, but it is best to wait for more than one year before using dot matrix laser. Premature use can sometimes stimulate scar hyperplasia. After one year, the scar is stable, and the concave scar can be treated with dot matrix laser, but it can generally be improved. It's hard to be completely untreated.
