Vitamin B12 tweaks how genes behave in the facial bacteria of some people who normally enjoy clear skin. The activity changes of the facial bacteria promote inflammation and lead to pimples.
By shedding light on one mechanism behind B12’s role in acne, the UCLA finding may identify drug targets that lead to new treatments for acne.

The link is not new. A study as far back as 1979 noticed the link, and acne breakout is listed as a side effect of taking B12 as a medication, (though acne breakout is listed as “rare”). This study is fascinating because it revealed the biochemical mechanism of this relationship. While this research may not be clinically relevant to everyone, people on B12 supplementation (whether pharmaceutical or dietary), could potentially benefit from this study.
Vitamin B12 deficiency is much more common than having too much B12 in your diet. The culprit is either b12 pills, or things like Redbull and 5 hour energy. Don’t stop eating a healthy diet because there is B12 in it.
