Glyco 6 Glycolic Acid Cream

i have oily skin die to which i used to get a lot acne in the past. my skin is now clear of all the acne but the horrible came scars are left behind. then my doctor suggested me to use Glyco 6 Glycolic Acid Cream to listen the acne scars. i felt the texture of this cream a little heavy for my oily skin. it used to leave an oily layer on my already oily skin. hence i used ot during night time. I used regularly for more than 2 months but it didn't make any difference on my scars. total disappointment.
