Lash serums are one of the few beauty products that have earned the title of "miracle worker." Over time, regular slicks of the stuff can help to keep your lashes healthy and nourished, preventing them from breaking off and providing an ideal environment for growth. With enough use, many people have even sworn off lash extension appointments altogether. But while Mona Gohara, MD, a New Haven board-certified dermatologist, is totally on board with the stuff, she wants you to proceed with extra caution when introducing it into your routine.

In the latest episode of Dear Derm, Dr. Gohara explains that, while lash serums can be great, they often come with the risk of causing the skin around your eyes to darken. "I'm all about lash-enhancing serums right now—just be careful of the hyperpigmentation, because sometimes that can be not-so-easy to fade down," says Dr. Gohara. "So don't blow it off, but just be sure to take stock of it and make sure it's really not discoloring your skin that much."

Lash serums typically work by using strengthening and moisturizing ingredients—like peptides and fatty acids—that stimulate hair growth, nourish your lashes, and keep them from breaking off (kind of like what conditioner does for your hair). The result, of course, is thicker, fuller-looking lashes that will save you a trip to the extension bar. However, as one of our editors discovered for herself in the video, studies have shown that one of the adverse side effects associated with these serums is hyperpigmentation around the eyelids. While typically rare, it does happen, so it's important to pay close attention to your skin when starting a lash serum for the first time. The best way to remedy the situation, says Dr. Gohara, is to stop using the serum.
