Can biotin make acne worse? 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.
Does biotin make you break our? Vitamin B5 helps to regulate the skin’s barrier function (including sebum production), so when excessive biotin is introduced, the vitamin B5 cannot be properly metabolized, the environment of your skin barrier is compromised, and you’ll become more prone to breaking out.
