Does Biotin Cause Breakouts? Derms Respond To The Common Concern

Those prone to breakouts tend to tread quite lightly when adding new products to their routine, be it topicals or supplements (since what you consume can totally show up on your skin).

If this resonates with you, then you've probably heard whispers that biotin supplements can increase breakouts—but is that actually true?

First things first: Does biotin even cause breakouts? "Currently, there is not enough evidence to suggest that biotin supplements cause breakouts, despite anecdotes to the contrary," says board-certified dermatologist Gloria Lin, M.D., FAAD, of Schweiger Dermatology Group in NYC.

In other words: The correlation has not been clinically proven, but it also hasn't been disproved either. Dermatologists and acne specialists—like Danielle Gronich, CEO of San Diego Acne Clinic and Clearstem—have anecdotally seen this common reaction a few times before and have a theory as to why it may be happening. 

"There is a theory that biotin supplementation may interfere with vitamin B5 (pantothenic acid) absorption since they utilize the same pathway. Pantothenic acid is thought to be important for the normal function of the epidermis, or top layer of the skin, so potentially having less of this might cause acne," Lin explains. 

However, biotin-induced breakouts won't happen to everyone. "Based on the possible mechanism of action, it is possible to occur in anyone, but those who are more prone to acne may be more susceptible," board-certified dermatologist Marisa Garshick, M.D., FAAD, explains. 

Does this mean you should avoid biotin forever? Not necessarily. If you do supplement with biotin, be it in a beauty supplement or multivitamin form, make sure it's coupled with pantothenic acid for the sake of balance. Even on its own, B5 is quite beneficial for the skin. (Topically, it's known as panthenol.)

"Pantothenic acid (vitamin B5) is amazing for acne—it helps with oil by regulating testosterone surges (kind of a natural alternative to spironolactone1), and it also helps with digestion, which is critical for those who are acne-prone," Gronich says.
