Clindamycin / tretinoin
"This gel is amazing. At the beginning of the year I went from clear skin to a full on breakout all over my cheeks and chin of mostly cystic acne. I started using the gel after a prescription pill did not work and it literally saved me. At first I did not see any difference and my skin got much worse but I read that's what happens with this gel and decided I would stick it out for 3 months. after about 2 months of bad acne I finally started seeing results and now 3.5 months into the treatment am now acne free!"
