I would ALWAYS have a breakout by like day 2 of using 2500 mg of biotin with a multi vitamin. However, I read that if you mix b50 with biotin it decreases the chance of acne. So far so good...
Me too. I have never had any biotin break-outs, which is surprising as I have a history of acne . I even increased my intake from 2000mcg to 5000mcg and so far, so good . Guess its the b-complex plus drinking lots of water thats helping
