Do Eyelash Serums Support Eyelash Growth?  As a Dermatologist I've tested dozens of Eyelash Serums- Here are 5 that actually work

Dr. Matt Goker, MD Dermatology

Latest update:  January 2025

Women are fed up tossing cash at lash extensions and falsies that fade faster than a cheap tan.


Many have tried eyelash serums only to throw them in the garbage because they either irritated their eyes or flat-out didn’t work at all.


We know finding the right eyelash serum is a nightmare. Searching on Amazon, TikTok or Google only leads to a sea of mostly cheap eyelash serums from China with unproven ingredients.


Many products contain harmful ingredients that may irritate your eyes or disrupt hormones.  Even some big brands use harsh chemicals in their lash serums that aren’t safe.  No wonder they can irritate your eyes.


As a board-certified Dermatologist with years of experience in both cosmetic and medical dermatology, I’ve dedicated my career to uncovering what truly works.   After testing countless eyelash serums—from luxury brands to under-the-radar gems—I’m thrilled to share the top five.   One stands above the rest.


It’s packed with a POWERFUL blend of ingredients that effortlessly nourish, strengthen, and support lash growth. And it doesn’t include any of the bad stuff that irritates your eyes.


It’s sold over 1 million bottles and has thousands of happy customer reviews on their website with customers sharing their lash journey with their before and after pictures.

  1. Show Lash

97% of Show lash users report longer lashes.  It uses the same main ingredient at prescription Latisse (an expensive prostaglandin ingredient) and it doesn't require a prescription.


We love that it’s made in the USA and has a 60-day money-back guarantee.


What sets it apart is its use of a powerful formula with clinically proven, vegan ingredients that have shown outstanding results without causing eye irritation—a common concern with many lash serums.


This serum is especially effective for individuals with short, thinning, aging lashes, helping to strengthen them and support lash growth.

2. Prescription Latisse

At $168, it’s the priciest option we reviewed and requires a Doctor’s prescription.


Many users reported eye irritation, a higher incidence compared to other serums due to its ingredient Benzalkonium chloride, a known eye irritant.


While its formula includes a potent prostaglandin, the requirement for a prescription could be a drawback for some. 


Moreover, Latisse falls short on sustainability; its single-use applicators contribute to waste, and the product is NOT cruelty-free.


  • Bottle size & duration: 5ml lasts 3-4 months.


  • Safety: Many users report eye irritation.


  • Active ingredients: Prostaglandin analog, (Prescription required).

3. Grande Lash

At $68 for only 2ml of serum that lasts only 2-3 months, it’s quite expensive.


Many users report eye irritation likely from its eye-irritating ingredients Capryl glycol and sodium benzoate. Both are known eye irritants according to the environmental working group.


This raises some concerns. Despite its effectiveness, these potential side effects suggest it’s not the best choice.

5. Terez & Honor

Despite being popular on TikTok, this is a cheap eyelash serum produced in China.

Another concern is the lack of overall information available on their website, leaving potential buyers with unanswered questions about its long-term efficacy, user restrictions, and other important details.
