Hi. Unrelated, but I love your pfp and banner. Envy is one of my favorite fma characters
Biotin gave me the worst breakout in my life and I have decent skin.
I would just take note of the daily value percentage because the concentrations of the biotin can be huge. A lot of these pills and vitamins that are selling have like 1,000% and 30,000% percent which is what I am assuming is the main reason my skin started freaking out the first time. I'm guessing they do that because there is no clinical limit to the dosage (?) but obviously people will respond to the intake differently.
I searched for and used another supplement that was only 70-100% (forgot) and it worked fine with no more acne, but I stopped in paranoid fear of another breakout.
