11 Best Eyelash Growth Serums: Tried & Tested Formulas for Maximum Length And Volume

Even the best mascaras and eyeliners can make our lashes dry and brittle, making them more prone to breakage. Vigorous makeup removal can exponentially increase the amount of lashes we shed each evening, while eyelash curlers can place stress at the base of our lashes, prising them out early. Long-wearing and waterproof mascaras are even worse, sometimes requiring intensive removal processes that leave our skin raw and our eyelashes totally frazzled.

Then there's the issue of false eyelashes and lash extensions, which can create damage to our hair follicles by overloading and putting too much weight on the lashes. And if you're a fan of wearing sleep masks at night, you should also know that they can cause friction and tug at lashes, encouraging them to shed prematurely, as well as bad habits like rubbing your eye area at the end of a long day (even though it feels so good).

Which eyelash growth serum is the best?

RevitaLash is a brand behind one of the most popular eyelash enhancers to date. This hair serum has been praised by the likes of Meghan Markle, largely due to its ability to target hair growth by simultaneously defending against environmental damage with antioxidant-packed green tea and the BioPeptin complex. Our Senior Visual Editor, Chelsea Hughes, reviewed the RevitaLash Advanced Eyelash Conditioner over the course of six weeks, and this is what she had to say: “To sum this product up; I’ve had numerous friends and family physically inspect my lashes to check whether or not I’m lying about them being real. The improvement is phe-nom-en-al!” Now, if this doesn't convince you, we don't know what else will.

How do eyelash serums work?

"Eyelash serums help to grow your natural lashes, making them longer and thicker after continued usage – it is a commitment, but worth it for beautiful, natural lashes," explains Nima Pourian, founder of Uklash. “Eyelash serums absorb into the lash and brow follicles to help stimulate growth, reducing fall out and enhancing the thickness of hair by strengthening roots.”

According to Claire Larsen, global master educator at RevitaLash Cosmetics, eyelash serums are similar to a hair conditioner. "They hydrate the hair with conditioning ingredients for shine and flexibility, to prevent brittleness and breakage, they strengthen the hair with ingredients rich in vitamins and strengthening peptides," she shares. “They protect the health of the hair with free-radical fighting antioxidants and they enhance the overall beauty of the lashes for a healthier-looking lash.” "A comprehensive formula will contain a blend of ingredients like conditioners, vitamins, antioxidants and peptides to have a multi-faceted approach to beautifying the lashes and keeping them strong and healthier-looking," Claire explains.

How long does it take to notice the results?

According to Claire, results usually differ depending on the individual, however, the growth is often noticeable after six weeks of regular, daily use. "We conducted an independent consumer study with 63 participants. After six weeks of daily directed use, 98% reported improved lash appearance, 98% reported healthier-looking lashes, and 98% reported stronger lashes."
