I am 20, and ever since my acne started I been worrying about my apperance. I look really unattractive, and my face is with little spots and blemishes.

I recently came across differin from my doctors, I wanted you all to share experience of this product and tell me if its effective. Also if you have used it, how long did it take for any effect?

Please do give me any other advice, I am really worried and downhearted about my grotesque apperance.
