Long, glossy lashes remain a beauty staple, but the way we achieve them has evolved. Instead of multiple coats of mascara, growth serums have become the go-to, now more sophisticated and credible than ever. Modern formulas focus on strengthening at the root using peptides, proteins, and conditioning ingredients like vitamin E, hyaluronic acid, and castor oil to support healthier growth over time.
Because lashes grow in cycles, results are gradual rather than instant. I tracked changes in length, thickness, and condition over several months. The following serums genuinely impressed me, from RevitaLash to L'Oréal and more.
A firm favourite and one of the OG lash serums, RevitaLash works by slowing down the growth cycle, so lashes stay at fuller length for longer. Created by an ophthalmologist to help his wife regain lash confidence after cancer, it contains peptides, moisturising agents, and nourishing botanicals. I found my lashes looked noticeably more conditioned, thicker, and longer after roughly six weeks, though it is nearly ten times more expensive than my budget pick.
Another impressive formula uses castor oil, vitamin B5, and hyaluronic acid to strengthen and nourish. It can even be brushed on as a base coat before mascara. After three weeks, I noticed lashes looked more conditioned and a little longer, though not dramatically. This is a great option for anyone looking to improve lash condition post-extensions.
For those seeking a multitasker, an eye serum-meets-lash booster targets signs of ageing around the entire eye area. It contains rhamnose, ceramides, and light reflectors. While it didn't give dramatic results, it improved lash condition and brightened the eye area after a month.
A serum using hyaluronic acid, peptides, and biotin is ideal for sparse lashes. Its recommended usage is eight to 12 weeks. I experienced slight redness that subsided after skipping a night, but there was a visible difference in length and condition after eight weeks. Another well-priced option uses a pen applicator and plant stem cells from a rare Swiss apple, promising more volume in 15 days.
