7 Serums For Longer Lashes & Fuller Brows

Ashley Batz / Bustle

Back in the day (like five years ago), if you were born with long lashes, you wore mascara, and if you were born with short lashes you wore mascara and no one knew the difference. Thanks to the blessing and curse that is the makeup-free selfie, the best serums for eyelash growth have become a hot topic. But how many of us can say with certainty that we know just how the heck these miracle formulas work and whether they actually can grow your eyelashes?

Unless your hand is confidently sticking straight up in the air, admit it: You're just as mystified by them, aren't you?

Well, let's get to the bottom of eyelash serums by starting with effective ingredients — the only reason any beauty product is worth a penny of our money or a second of our time. Whether you have lash goals, brow goals, or both, dermatologists say that the best formulas contain peptides. These peptides can add fullness to brows and lashes, while castor oil and Vitamin E are sometimes added to strengthen hair follicles and prevent hairs from shedding as fast.

Which leads us to an important possibility: The results you're noticing from continued use of a growth serum could either be the effect of stagnant hair shedding or more hair growth in your lashes and brows. Either way, if these top-rated eye lash growth serums work, does it even matter?


A Cult-Favorite Korean Serum That Fans Say Delivers Real Results
