It would be best to see a photo to see the extent of the scarring and show your photos before. I am so sorry you had a difficult experience. Fraxel is typically a fabulous laser. Please consult a board certified physician with a great deal of experience with acne, scars, and lasers for the best cosmetic results.
I suggest seeking a laser expert for advice, a second opinion. Ice pick type scars never do well with just fractional laser alone, often they need surgical removal and/or fillers to the area. I suggest seeking an expert's advice, someone who has a lot of experience particularly in laser and treating acne/facial scars. We would gladly see you at our office anytime. If you have "marks" from the laser, an in person consultation can determine if this is scarring or post-inflammatory skin changes, which are treated differently. Best, Dr. Emer.
