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.

How we selected the best lash growth serums

I extensively researched beauty products based on the best active ingredients, expert recommendations, and thousands of customer reviews. I focused on ease of use and application process, short-term and long-term effects, safety, popularity, availability, and price point.

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.
