i had a depressed scar on my forehead so i did a scar revision surgery(4 months ago)...but as i have been recovering,the surgery seems to have left white stretch marks behind. I have been apply contractubex gel for a month now...it seems to have made my skin soft and more levelled but the white stretch marks are quite obvious(as i am brown)...can someone suggest me some cream that will return my skin to normal color?
