Between mascara, falsies, and extensions, there are plenty of ways to fake darker, fuller, longer lashes. But dabbling in all of the above can often lead to sparse and damaged lashes if you're not looking after your natural set in between.
So, how do you look after your natural lashes? One suggestion that pops up on TikTok time and time again is caster oil. The other is lash serums.
If you've ever wondered what's actually in those tiny vials of pricey lash potions that promise Bambi-like results — and, more importantly, if they actually work — you're not alone.
Most lash serums are formulated with ingredients like caster oil, peptides, vitamins and omega fatty acids, which help to improve overall lash health and reduce shedding by hydrating and conditioning lash hairs.
"Over-the-counter last serums typically contain peptides that promote healthier lashes, which can lead to enhanced thickness and length," board-certified dermatologist Joshua Zeichner, MD, tells Refinery29.
While there is still very limited research regarding the efficacy of lash serums, and results vary depending on individual use, experts generally agree that they help with lash health.
