Longing for long lashes? a One way to make your eyes look bigger, brighter, and full of energy is to take one of our top lash growth serums for a spin. Eyelash serums are a popular alternative to eyelash extensions, promising to grow lashes with hyaluronic acid, peptides, panthenol, biotin, or castor oil. (Coincidentally, these are also ingredients you’ll find in the best night creams and best long-lasting lipsticks, among other commonly used cosmetics.) By applying a targeted conditioner along your lashes consistently, you might be able to achieve flawless, healthy, full lashes in just a few weeks.

What to look for in lash growth serums

  • Efficacy: Look at reviews that list both short- and long-term results
  • Ingredients list: If you’re looking for hydration, avoid any known allergens that might affect you.
  • Application and ease of use: If you’re the type of person who requires an applicator, note how the product is packaged. Many include a wand like a mascara, but some are plain oils or pump systems.
  • Price point and product size: Pay attention, as these vary greatly!
  • Personal goals: Some eyelash serums are better for lengthening while others focus on volume or regrowth

What else you should know about lash growth serums

Eyelash serums are not for everyone, especially those with sensitive eyes or a history of eye health issues. Over-the-counter eyelash serums are considered cosmetics rather than medications, so they may contain ingredients not approved by the FDA. Check with your eye doctor for the best information.

Our top picks for the best lash growth serums

While you might know where to go for the best eyeshadow palettes or the best eye creams, lash serums have a niche following. Some need to lengthen their lashes, some are looking for thicker lashes, and others are looking for medical or cosmetic ways to regrow eyelashes. To help you choose the best eyelash growth serum for you, we listed the top 15 serums in specific categories. Take note of the price and size of the product—packaging varies significantly by brand. The following list includes the best lash serums to help your eyelashes look stronger, longer, fuller, and more lustrous.

LATISSE® (bimatoprost ophthalmic solution) 0.03%

Just like how even the best skincare tools can’t quite replicate the full effect of a professional procedure, a prescription treatment is a bit more effective than over the counter lash growth serums. Latisse is the only FDA-approved eyelash serum for eyelash growth as of publication.

Because it's so powerful, be sure to talk to your doctor about possible risks such as eye irritation, eye color changes, and eyelids darkening. If you wear contact lenses, you’ll need to remove them before application (and soft lenses may absorb the product). Consider switching to eyeglasses—our list of the best places to buy glasses online is a good starting point.

Our top 3 picks

How do lash growth serums work?

Eyelash growth serums aim to work with and enhance eyelashes' natural growth cycle, called the anagen phase. Most packages provide detailed instructions on how to use (and how often to use) their specific lash serum, and what results generally look like. Most often, you apply the serum to the lash line with an included applicator, similar to applying liquid eyeliner. Others are applied by pumping a dose onto your fingers and dabbing it along your lashes. They often require daily use for peptides or collagen to affect your lash line. Many reviewers say eyelashes will appear longer, stronger or fuller, with results showing up for most between 2-6 months.

Frequently asked questions (FAQs)

Do eyelash growth serums really work?

Thousands of beauty experts and online reviewers say they do, but it does take time. Most eyelash serums take two to six months to see an effect, and consistent application is important.

Is eyelash serum safe for your eyes?

Yes. While the Federal Drug Administration (FDA) does not approve over-the-counter eyelash serums, cosmetics companies do ample testing. Each product reacts with your chemistry differently. Stop using the product immediately if you notice any signs of discoloration or irritation. Sensitive skin or eyes? Check to see if your chosen product is dermatologist- or optometrist-approved.

How do you apply eyelash serum?

Apply eyelash serums to your lashes using the included applicator, just like you would apply liquid eyeliner. Pump-style applications allow you to deposit serum onto your finger and apply manually onto your lashes.

How long will it take to see a difference in the length and volume of my eyelashes?

Efficacy depends on product and each user’s genetics and beauty regimen, but with most eyelash serums on this list, users started to see results in four to eight weeks, with the best results after six months.

Can you use lash growth serums with lash extensions?

Yes, as long as they are not oil-based. Stay away from castor oil, sunflower seed oil, and other mineral oils, as they naturally break down the adhesive in lash extensions. You can continue to use non-oil-based lash growth serums at any time.
