I am 27 yrs old Indian guy,I had some amount of hyperpigmentation along with a few superficial scars on the face. I had 3 sittings of fraxel refine at an interval of 3 weeks each. Now i am considering fraxel restore. After having fraxel refine,can i decrease the sittings of fraxel restore? or will i have to undergo the claimed sittings(minimum 3) for the elimination of the above said condition? How much gap is required b/w 2 sittings? plz highlight potential side effects too.Thnx very much.
