Before testing the top eyelash growth serums, I often joked that I had baby lashes—short, fine strands that even the best lengthening mascara couldn’t improve. Constantly applying strip lashes or booking expensive extension appointments quickly became frustrating. I wanted a solution that could deliver long-term results, helping lashes look thicker, stronger, and longer over time. As I soon discovered, many others were searching for the same kind of lash-enhancing solution, hoping to restore fullness without relying on temporary fixes.
Alopecia areata, diagnosed nearly ten years ago, caused Vogue beauty shopping writer Conçetta Ciarlo to experience repeated periods of lash shedding and slow regrowth. She initially tried Latisse, the only FDA-approved lash treatment, but the prescription requirement and mild lash line darkening made it less appealing. While her lashes eventually returned, they were less dense and more fragile. Looking for something easier to access, she began testing over-the-counter serums, many popular online, in hopes of finding a formula that offered visible improvement without unwanted side effects.
Vogue’s Top-Rated Eyelash Growth Serums
Through extensive testing, Vogue editors evaluated a range of eyelash-enhancing formulas designed to support healthier-looking lashes. These products focus on strengthening lash fibers, improving overall density, and reducing breakage over time. Each option below was selected based on performance, ingredients, and ease of use.
“Eyelash growth serums help condition and nourish lash hairs, which can result in a fuller appearance with consistent application,” explains board-certified dermatologist Marisa Garshick, MD. By supporting lash health, these formulas may also make lashes less prone to damage and fallout.

Although lash types vary—short and curly versus long and straight—both Ciarlo and I have seen positive results from long-term serum use. According to board-certified dermatologist Purvisha Patel, MD, daily application is key, and most users should expect to wait at least one month to notice changes.
Best Overall Lash Serum: Vegamour Gro Lash Serum
Vegamour’s Gro Lash Serum stands out for its clean beauty formula made with naturally derived ingredients that are ophthalmologist-approved. The blend includes peptides and mung bean extract, which is rich in selenium—an often overlooked mineral believed to support healthy hair growth. Notably, this serum is prostaglandin-free, making it a preferred option for those concerned about skin discoloration. Many editors rely on it to maintain lash strength and reduce fallout without irritation.
Key ingredients include red clover, mung bean extract, and peptides. The formula contains no PGAs and is applied to both the upper and lower lash line twice daily for two months, then once daily. It is vegan, cruelty-free, and free from parabens and sulfates.
Best Prostaglandin Formula: Grande Cosmetics GrandeLASH-MD
GrandeLASH-MD is widely recognized for delivering noticeable lash growth within weeks. Its formula combines amino acids, vitamins, and antioxidants to support fuller-looking lashes. Hyaluronic acid helps hydrate and condition, while the thin applicator allows for precise application along the lash line. Some users report mild lash line darkening, which can occur with prostaglandin-based formulas.
This serum includes isopropyl cloprostenate and does contain PGAs. It is applied once daily to the upper lash line and is ophthalmologist-tested, cruelty-free, and suitable for contact lens wearers.
Best Conditioning Serum: Shiseido Full Lash & Brow Serum
Shiseido’s lash and brow serum focuses on conditioning existing hairs rather than stimulating new growth.

This gentle formula is ideal for those seeking breakage prevention and everyday maintenance for both lashes and brows.
The serum is PGA-free and applied morning and night. It is dermatologist- and ophthalmologist-tested and works best as a daily conditioning treatment.
Best Castor Oil Option: Sky Organics Organic Castor Oil Serum
Sky Organics offers a pure castor oil formula for those preferring a natural approach. Castor oil is widely used to help improve the appearance of dry, brittle lashes and support overall lash health. While results may take longer, this option is valued for its minimal ingredient list and versatility for both lashes and brows.
Made with 100% virgin castor oil, the formula contains no PGAs and is applied nightly. It is vegan, organic, and best suited for those whose skin tolerates richer oils.

This approach helps improve overall density while reducing breakage, making it suitable for both lashes and brows.
The serum is fragrance-free, vegan, and ophthalmologist-tested. It is applied once or twice daily and left on without rinsing.
Best Keratin-Infused Formula: Kosas Grow Potion Lash & Brow Serum
Kosas GrowPotion combines keratin, peptides, and vitamin B5 to support healthier-looking lashes and brows.
