I wanted something that would promote healthy hair, skin, and nails, so I went looking for a pure beta-carotine supplement, but I couldn't find one, so I found biotin and bought it instead.
Upon researching it on the net it seems that it isn't a good thing to take if I don't have a biotin deficiency. I'm not sure of this though, i've read different things.
My question is, is it worth taking? I get blackheads that i'm trying to get rid of. Is there another vitamin I should buy instead?
