Hi, thanks for your query.
You are concerned for acne scars
and dark spots. You have already undergone 2 laser
sessions and 2 dermarollers and there is 20 % reduction .
You are taking appropriate treatment for scars. The response to treatment for scars is however slow. I suggest you to continue fractional laser and dermaroller for scar reduction. It may not be possible to completely get rid of scars within six months that is before your your marriage. But as you continue these procedures there may be significant reduction in the scars.
Hope this solves your query.
Wish you all the best.
