Eyelash growth serums have surged in popularity as a modern alternative to traditional mascaras and extensions, promising to enhance lash length, volume, and health. These innovative formulas leverage growth-encouraging ingredients like peptides, vitamins, and natural oils to transform your lashes over time. In this comprehensive review, we tested numerous serums over several months to identify the best options for 2025, focusing on effectiveness, value, and suitability for different needs.
How We Tested the Eyelash Serums
Our testing process spanned multiple months, with each serum applied to clean lashes according to brand instructions. We evaluated changes in length, volume, curl, and overall lash health, taking progress photos to track differences. The goal was to find products that deliver glossier, healthier lashes, with length as a bonus. Our reviewer, Anita Bhagwandas, an award-winning beauty director with over 15 years of experience, ensured rigorous and trustworthy assessments.
Top 10 Eyelash Serums for 2025
1. RevitaLash Advanced Eyelash Conditioner – Best Overall
Priced at £139, this serum is a beauty industry favourite, created by an ophthalmologist to help regrow lashes post-cancer treatment. It uses peptides, moisturising agents, and botanicals to slow the growth cycle, keeping lashes fuller for longer. Applied nightly, it showed noticeable conditioning, thickening, and lengthening within six weeks, though it is significantly more expensive than budget options.
2. L'Oreal Paris Clinically Proven Lash Serum – Best Budget Buy
At £15, this serum features castor oil, vitamin B5, and hyaluronic acid to strengthen and nourish lashes. Easy to apply with a brush, it can be used as a base under mascara. After three weeks, lashes appeared more conditioned and slightly longer, making it ideal for post-extension care, though results are not dramatic.
3. Vichy LiftActiv Anti-Aging Serum 10 Eyes and Lashes – Best for Multi-Tasking
Costing £30, this serum targets ageing around the eyes while boosting lash health. With ingredients like rhamnose and ceramides, it brightens the eye area and improves lash condition over a month, though it lacks the dramatic growth effects of specialised serums.
4. UKlash Eyelash Conditioning Serum – Best for Sparse Lashes
Priced at £38, this serum uses hyaluronic acid, peptides, and biotin to enhance sparse lashes. Visible improvements in length and strength were noted after eight weeks, though some users experienced temporary redness.
5. Indeed Labs Peptalash – Best for Fast Results
At £19, this pen-applicator serum promises results in 15 days using plant stem cells and peptides. It improved lash health within two weeks, though the applicator can be tricky to use.
6. Lancôme Cils Booster Activating Serum – Best for Dry Lashes
Costing £30, this luxury serum with hyaluronic acid and amino acids nourishes dry lashes, showing better condition and slight growth after a month. Its thicker formula is ideal for overnight use.
7. Luna Nectar The Moon Boost Tonic for Lashes and Brows – Best for Vegans
Priced at £60, this vegan serum uses vitamin E and argan oil to nourish lashes and brows, delivering glossier, thicker results in under three weeks. It is fragrance-free and gentle on sensitive skin.
8. Elizabeth Arden Prevage Clinical Lash and Brow Enhancing Serum – Best for False-Lash Wearers
At £79, this serum reconditions parched, damaged lashes with vitamins and peptides. After a month, lashes looked longer and stronger, suitable for frequent false-lash users.
9. RapidLash Eyelash Enhancing Serum – Best Mid-Range Serum
Costing £19, this serum uses polypeptides and biotin to strengthen lashes, showing improvements in length and condition over eight weeks, though results are less dramatic than premium options.
10. No7 Lash Impact Serum – Best Hypoallergenic Serum
Priced at £14, this hypoallergenic serum with keratin offers a subtle improvement in lash condition over eight weeks, making it a good entry-level option despite a less user-friendly brush.
Frequently Asked Questions About Eyelash Serums
Do eyelash growth serums really work? Yes, but they require consistent use over a 90-day lash cycle for best results. Ingredients like peptides and conditioning agents promote growth, but effectiveness varies by individual.
Do eyelash serums cause irritation? While many are hypoallergenic, the sensitive eye area can react. Stop use if redness or itching occurs and consult a doctor, especially with existing eye conditions.
What happens if you stop using eyelash serum? Lashes will return to their natural length once application ceases, as serums work only with continuous use.
Final Verdict on Lash Serums
RevitaLash delivered the most dramatic length improvements, while Luna Nectar excelled in conditioning. For budget-friendly options, L'Oreal and No7 serums provided good conditioning, though with less pronounced results. Choose based on your specific needs, whether for luxury performance, vegan formulas, or affordable care.
