Clindamycin
"I have had moderate adult acne for many years, and over the counter never touched it. Besides the regimen was always annoying and time consuming.  I started this about 2 weeks ago after asking my PCP for something to help my acne, as I am getting married in May. I have seen a huge improvement in 2 weeks.  My skin tone has also improved.  I am very thankful for this medication and I use it twice a day.  It keeps pimples from becoming large and irritating."
