Discover the top eyelash growth serums of 2025, expert-tested for length, volume, and healthier lashes.
Best Eyelash Serums for Growth in 2025
Long, fluttery lashes are a beauty staple, and eyelash growth serums promise to deliver just that—naturally. The market is flooded with options, but which ones actually deliver? In 2025, beauty editors and consumers alike are putting these products to the test. This guide covers the top-performing serums, how they work, what to look for, and expert advice to help you choose the best formula for your lashes.
What Do Eyelash Serums Actually Do?
Eyelash growth serums and conditioners aim to strengthen, lengthen, and volumize your natural lashes. Some formulas contain active ingredients that may extend the growth phase of your lashes, while others focus on conditioning to prevent breakage and add shine. The only FDA-approved serum for eyelash growth is Latisse, which contains bimatoprost and is available by prescription. Over-the-counter (OTC) options rely on peptides, vitamins, and botanical extracts, which may improve lash appearance but lack the proven growth stimulation of prescription treatments.
How Do Eyelash Growth Serums Work?
Latisse (bimatoprost) works by prolonging the anagen (growth) phase of the eyelash cycle, allowing lashes to grow longer before they naturally shed. Consistent daily application is required, and results typically appear within 4–6 weeks. The effects are not permanent; if you stop using it, your lashes will gradually return to their original state.
OTC serums, on the other hand, primarily condition lashes. Ingredients like peptides, hyaluronic acid, amino acids, and plant oils can make lashes appear thicker, shinier, and less prone to breakage—but they do not stimulate new growth in the same way as prescription options. Clinical data for OTC serums is limited, so expectations should be realistic: these products can enhance lash health and appearance, but dramatic length increases are less likely.
What Should You Look For in an Eyelash Serum?
- Key Ingredients: Peptides, hyaluronic acid, amino acids, biotin, panthenol, and plant oils (e.g., castor, coconut, argan) are common in effective OTC serums. Look for formulas free of irritants if you have sensitive eyes.
- Hormone-Free Options: Some serums are prostaglandin-free, reducing the risk of side effects like irritation or darkening of the eyelid skin.
- Application: Most serums are applied once or twice daily along the lash line. Consistency is crucial for results.
- Side Effects: Prescription formulas like Latisse can cause side effects (e.g., eye redness, darkening of the iris); OTC options are generally gentler but may still irritate sensitive users.

Other Notable Eyelash Serums

Expert Insights: Do Eyelash Serums Actually Work?
Dermatologists emphasize that Latisse is the only eyelash serum with robust clinical evidence for growth. OTC serums can condition lashes, making them appear thicker and healthier, but they are not proven to stimulate new growth in the same way. If you’re experiencing significant lash loss, consult a doctor to rule out underlying causes such as alopecia, medication side effects, or other medical conditions.
How to Use Eyelash Serums for Best Results
- Apply the serum daily (or as directed) along the upper lash line.
- Use a clean applicator to avoid contamination.
- Be consistent—results may take several weeks to appear.
- If irritation occurs, discontinue use and consult a professional.
Frequently Asked Questions (FAQs)
Q: How long does it take to see results from eyelash serums?
A: Prescription options like Latisse may show results in 4–6 weeks. OTC serums often require at least a month of consistent use, with full results visible after 2–3 months.
Q: Are eyelash serums safe?
A: Most OTC serums are safe for most users, but those with sensitive eyes should look for gentle, fragrance-free formulas. Prescription serums like Latisse have a higher risk of side effects and should be used under medical supervision.
Q: What’s the difference between prescription and OTC eyelash serums?
A: Prescription serums (e.g., Latisse) contain active ingredients that stimulate lash growth. OTC serums primarily condition, using peptides, vitamins, and botanical extracts.
Q: Can eyelash serums cause side effects?
A: Possible side effects include irritation, redness, and, with prescription formulas, eyelid darkening or iris color changes. Always patch-test new products and consult a doctor if you have concerns.
Q: What should I do if I experience lash loss?
A: Consult your doctor to identify the cause. Lash loss can result from medical conditions, medications, or aging, and a lash serum may not be the right solution.
Final Thoughts
Eyelash serums can be a worthwhile addition to your beauty routine, especially if you’re seeking stronger, healthier-looking lashes. For guaranteed growth, Latisse remains the gold standard, but OTC options can deliver noticeable improvements in lash condition and appearance. Always choose a formula suited to your needs, prioritize gentle ingredients if you have sensitive eyes, and maintain realistic expectations for results. And remember: when in doubt, consult a dermatologist or ophthalmologist to ensure the health of your eyes and lashes.
