Why do I breakout when taking biotin? You may have heard many beauty influencers insist on a link between biotin and breakouts, but new research suggests that there is minimal evidence that supports the claim that taking biotin supplements will worsen acne.
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.
