I had been on OTC for about 9 months, and it definitely didn't clear anything, and my acne actually got worse too (but that may have been because of stress). I'm on desogen now, which is supposed to be good too, and my face has actually been clearing. I can't tell if it's because of the new pill, or the new cleansing routine I've been using, or both. Anyway, OTC didn't help me at all, but everyone's different. Hope it works for you
