Ideally, we'd all have long, beautiful lashes, the kind you likely had as a child before you grew up and started rubbing your eyes or wearing mascara that dried them out. But as you grow older, the look of long, beautiful lashes becomes harder and harder to achieve no matter how many lengthening mascaras you try. Plus lash extensions and falsies can get expensive and they can be a pain to maintain. That’s where lash growth serums come in.
While prescription formulas used to be the only option, lash serums are now available at a variety of price points, from drugstore to designer. Natural brands have created formulas as well and some are even used for both lashes and brows to help those of us who fell for the thin brow trend back in the ‘90s.
Read on to learn more about the best lash growth serums available now.

Best Budget: Etude House My Lash Serum
At this price, Korean brand Etude House's lash serum may seem too good to be true, but users swear by its ability to quickly and noticeably lengthen lashes. Its hero ingredient is panthenol, a derivative of vitamin B5 which assists in protein synthesis (hair is made up of protein).
