Pros
- Hypoallergenic
- Clinically proven
Cons
- Takes up to four weeks to see best results
Lumify—the brand best known for its brightening eye drops—makes a lash and brow serum that eye doctors, including Manhattan-based optometrist Jennifer Tsai, can get behind. The ingredient list is prostaglandin-free and includes peptides, hyaluronic acid, and biotin, which condition the lashes without irritation.
One satisfied customer says: “I have long lashes, but I usually lose a few when curling them and it takes a while [for them] to grow back. But with this serum, I noticed my eyelashes grow faster and a bit thicker too.” —Dianna
Pros
- Ophthalmologist-developed and -tested
- Packaging includes a hygienic pump design
Cons
- Requires clean-finger application
Developed and tested by an ophthalmologist, this lash and brow serum is safe for sensitive skin and eyes. It’s free of prostaglandin, parabens, phthalates, silicones, and fragrance. Plus, a note on packaging design: Unlike a commonplace spoolie applicator, the serum’s hygienic pump prevents transmission of bacteria caused by double-dipping into a tube.
One satisfied customer says: “Only 3 all-natural ingredients and made by an eye doctor so I can trust it isn’t going to cause any strange reactions. I’ve been loving it so, far and it hasn’t irritated my sensitive skin. Best of all my lashes are coming back!!” —Sophia

- Award-winning formula
Cons
- Contains dechloro-dihydroxy-difluoro-ethylcloprostenolamide (a prostaglandin analogue)

Pros
- Award-winning formula
Cons
- Shipping may take a few weeks for U.S. customers
Zamani also includes UKLash’s serum among her favorites, and Marie Claire and Cosmopolitan have ranked it as a top lash serum as well. Beyond biotin and peptides, the formula contains myristoyl pentapeptide-17, an amino acid peptide known for stimulating keratin (a protein that helps form hair). While the brand is based in the United Kingdom, as the name suggests, this lash serum can be shipped to customers in the United States.
One satisfied customer says: “As I went through menopause, my eyelashes not only became more sparse, I found myself losing individual lashes to the point of having bald spots on my lids. I tried a few different serums, but Uklash had the best effect, and it feels soothing on my eyes. My eyelashes are thick and long again.” —Sheri
Pros
- Dermatologist-tested
- Budget-friendly
Cons
- May take up to 16 weeks to achieve best results
For those looking to treat lashes and brows in tandem, Zamani recommends this serum by Shiseido. The formula is dermatologist-tested and contains arginine, which helps restore the condition of lashes and brows.
One satisfied customer says: “I have tried eight to ten lash serums this year. This one is the overall winner. The application wand is not thin but a sponge, which allows for wider coverage.” —Cynthia

This serum from Obagi Medical contains the brand’s trademarked Nouri-Plex Technology, a combination of targeted ingredients designed to address thinning and sparse eyelashes. The formula contains strengthening biotin, a nourishing proprietary lipid compound, sodium hyaluronate to attract and retain water, and panthenol (a.k.a. vitamin B5) for lash conditioning.
One satisfied customer says: “My esthetician told me about Obagi’s serum. It’s a bit pricey but it works! I’ve used other serums, including Latisse, and I think this works better than anything else I’ve tried. My friend thought I had gotten lash extensions.” —Kathy
Best for Under Makeup

One satisfied customer says: “I have been using this product for a couple [of] months now and am very impressed with the regrowth and growth of my lashes and brows. Most days I don’t use brow filler or mascara [because] I don’t need it. It took about two weeks to start seeing a difference, but it’s noticeable.” —Katrinia

How do eyelash serums work exactly?
“Eyelash growth serums stimulate the eyelash hair follicles to prolong the growth phase, also known as the anagen phase, of the hair growth cycle,” says Tsai. “This is the active phase where hair follicles produce new hair.” The ingredients may vary, but most OTC serums, she says, include “prostaglandin analogs (PGAs) or nourishing compounds like peptides, vitamins, and amino acids.”
When shopping for a lash serum, Tsai advises, “look for ones that contain ingredients like peptides and amino acids to stimulate hair growth, biotin vitamin to support healthy lashes, and hyaluronic acid to condition and prevent brittle breakage.”

Are eyelash growth serums safe?
Safety is a concern with anything applied to the delicate eye area. The only FDA-approved treatment for eyelash growth is Latisse, which requires a prescription. With eyelash serums sold over the counter, there are additional safety considerations.
“Eyelash growth serums are generally considered safe for most people when used as directed,” says Tsai. “However, there are some potential risks and side effects to be aware of. With products containing prostaglandin analogs, common side effects can include eye irritation, skin darkening, iris color change, and long-term use could lead to fat loss around the eyes, leading to a sunken appearance.”
What are prostaglandin analogs?
Because of potential side effects, both long- and short-term, many eye doctors recommend serums that are free of prostaglandin analogs.
“Prostaglandins are naturally occurring chemicals that have traditionally been used in ophthalmology, specifically in eyedrops to treat an ocular condition called glaucoma,” explains Zamani. When it was discovered that prostaglandins also increase eyelash growth, cosmetic companies began creating eyelash serums using prostaglandin analogs, which mimic the function of prostaglandin and encourage hair growth but can cause side effects. “These include eye redness, pain, itching, or dryness, skin pigmentation or iris pigmentation, fat loss around the eyes, and sunken eyes,” says Zamani. “If you’re noticing any of the above side effects, it’s best to discontinue usage immediately.”
