Why does biotin make me break out? Why Might Biotin Make You Break Out? Biotin can lead to breakouts in the way your body absorbs it and other vitamins. It’s not so much that biotin causes acne. It’s that it prevents your body from absorbing other nutrients that normally help counteract the effects of acne.
Can biotin vitamins cause acne? Currently, there is minimal evidence that taking biotin supplements causes acne. The logic behind such claims has more to do with pantothenic acid, or vitamin B5, than with biotin.
Can biotin make acne worse? “Biotin, also known as vitamin B7, and pantothenic acid, also known as vitamin B5, tend to compete with each other, and as a result can have negative effects on our bodies such as causing acne,” she says. Green explains that when vitamins B7 and B5 compete, an excess or shortage of either of these vitamins can occur.
