Hi Innovation,
The number of Fraxel re:pair laser treatments for acne scarring depend upon the degree of scarring and the individual patients healing response. At our initial consultation I inform my patients that for acne scarring it may take anywhere from one to three treatments separated by 4 to 6 months each. I have treated some patients successfully in one treatment while others have needed more treatments.
You should pre-treat your skin with hydroquinolone cream to minimize the chances for hyperpigmentation. Post treatment use a physical sun block and avoid sun exposure. Good luck and be well.
Dr. P
