I have been suffering from acne problem since last two years. Doctor had suggested me to use clindamycin Phosphate Gel and I am using it since then, though it provides relief from acne but always leave red/brown marks which never fades away. Now my face is full of these blemishes. Also, I still have to use the Gel whenever there is a new pimple, knowing that it will ruin the skin of my face. Is there any other effective solution which provides relief from acnes without leaving any mark. And please advise what can I do to get rid of the marks which are already there. Please help.
