So, i have already had two microdembrasion sessions, (1st session in February and 2nd session in March). When will i start seeing more significant results, as to seeing most of my acne scars disappear, some of the sun damage/suntan improve. i have seen a slight improvement, but i would like to see more improvement, and how many sessions more will be needed. i ask because if this is not going to improve more, than i dont want to waste money for no reason.
