It's been a long time!
Things were going well about 2 weeks ago, but then I started to take Biotin to grow my hair. I take 2500mcg per day, which is a pretty high dose. And then I had a breakout - my skin went to what it was like before I started the regimen.
I've seen effects of Biotin already, so I decided to stop taking it for now, and take it from time to time in the future instead taking it daily. I will stop taking it altogether for the next week to test whether Biotin is causing the breakout. It can be a menstrual breakout too, I'm not sure. We'll see.
