Scar depressions on the face, i.e. depressed facial scarring, are mostly related to acne, trauma and other factors, and can be dealt with through surgical treatment and physical therapy. 1. Surgical treatment: For patients with depressed facial scars caused by trauma, hyaluronic acid or autologous fat tissue can be used to fill in the localized depressions to improve the appearance of the depressions as prescribed by the doctor. Depending on the location and size of the scar, you can also consider whether it can be directly excised or scar reshaping. 2. Physical therapy: For depressed scars after acne healing, physical therapy such as fractional laser, erbium laser or gold radiofrequency can be used to stimulate the regeneration and rearrangement of subcutaneous collagen tissues in the depressed area under the effect of light and heat to improve the appearance of the depression. For patients with depressed facial scarring, it is recommended to go to a regular hospital and choose the appropriate treatment under the guidance of the doctor, and pay attention to the scientific care after treatment.
