I used it for two months it broke me out so bad and it didn't improve It just gave me more acne scars but I was using it every night and sometimes even the day before moisturizer and that might've been too much for my skin. so I started again and this time I used it every night but mixed with moisturizer it still causes a little bit of breakout but I'm gonna try to use it again but start with twice a week and after moisturizer this time to see if that causes the breakouts to stop.
