Lash growth serums are seeing increasing popularity. Once seen as gimmicks, they’re now a must-have in every beauty lover’s routine. Everyone wants beautiful natural lashes, but not everyone realises the secret to growing thick, healthy lashes starts with a lash serum. Forget the hassle (and potential damage) of eyelash extensions and add an iconic serum from brands like OLAPLEX and UKLASH to your routine for stunning, natural lashes, minus the fuss. Whether you want defined lashes on no-makeup days or to enhance your lashes before mascara, a top lash growth serum will transform your lashes with consistent use. We’ve broken down the science, how to use them, and our picks of the best lash serums to get you started.
How Do Lash Serums Work?
Lash serums work by doing two things to your lashes: conditioning and stimulating growth.
Just like the conditioner you use on your hair, a good lash serum hydrates, adds shine, and boosts flexibility, reducing brittleness and breakage that make lashes look shorter. Vitamins and peptides work together to strengthen and hydrate your lashes, helping them to look their best.
For growth, lash serums extend the anagen (growth) phase of your lash cycle, so your lashes grow longer and stronger. A full lash cycle takes 8-12 weeks, so applying your serum daily for that period will give you the best results. Key ingredients like hyaluronic acid, biotin, and castor oil strengthen the follicle, reduce fallout, and leave you with visibly fuller, longer lashes.
The key to success? Consistency. Whether you’re repairing damage from a rogue curler or just want to boost lash potential, daily use is a must.
How to Apply Lash Growth Serums
Before fully incorporating any new lash serum, always do a patch test to avoid any unwanted irritation or reactions—our eyes are too sensitive to take chances with.
Once you’re all set, apply the serum to clean lashes, stroking it along the roots of your upper lashes. Let it dry fully before continuing with skincare. It’s best to use your serum at night to let it work while you sleep, with any product transfer also giving your lower lashes a boost.
No need to overdo it! Applying lash serum more than once a day won’t speed up the process—it may even backfire. Stick to one nightly application for 12 weeks for the best results.
