The acne on your forehead is significantly deep. Your best treatment may be a combination of fillers to inject into some of the deep scars followed by Fraxel Laser. Fraxel (1550) will help with the scarring that you have. You will need approximately five treatments scheduled a month apart to minimize these deep scars. I recommend you find a board certified dermatologist with a lot of experience in Fraxel for the best cosmetic result.
