Tretinoin
"Once you are on this medication, DO NOT STOP. I tried a whole bunch of over-the-counter and prescription medicines for my facial acne but nothing seemed to work till I tried a combination of Tretinoin (.025%) and Clindamycin, both topical medications. A pea size amount of Tretinoin at night before bed and the Clindamycin lotion in the morning. For the first two weeks the medication seemed to work and my acne started receding. But then the acne came back, not as acute as before, but enough for me to notice that maybe the bacteria was winning the battle. Nevertheless, I stuck to it like my dermatologist recommended and within a few months my acne had spoofed away! I strongly recommend it. If the acne worsens, Be patient. Male-25"
