Elevate your lash game with expert-endorsed serums that redefine beauty standards.

Some eyelash serums offer a natural alternative to falsies and extensions, enhancing the volume and length of your lashes, but not all of them do their job or bring the desired results. Aging, on the other hand, can also cause lashes to become sparse or weak, which makes it more complicated to find the right serum that will help them rejuvenate effortlessly.

Lash serums are designed to promote longer, thicker, and darker lashes. They work by nourishing the lash line to encourage growth, strength, and resilience. Whether containing prostaglandins like Levaye’ and Latisse or conditioning ingredients, these serums typically show results in 2-4 months.

However, not all serums deliver the same results or are made with the same high-quality ingredients. To help you make a confident and wise decision, we gathered 26 medical aestheticians who rigorously tested various products over 4 months. Here, we reveal the top 5 performers, ensuring you find the perfect serum for your needs:

#1 LeVaye’ Show Lash Eyelash Serum

• Efficacy: 98% of our testers reported longer lashes
• Price: $93 $55.80 (they’re having a 40% off sitewide sale)
• Aging: 5/5
• Safety: Least eye irritation out of all serums we tested
• Active Ingredient: growth-enhancing prostaglandin (no prescription required).

Overall rating: ⭐️⭐️⭐️⭐️⭐️

LeVaye’s Show Lash Serum stands out among lash serums due to its impressive 98% efficacy rate for longer lashes and a current sale price of $55.80 (originally $93). It contains a growth-enhancing prostaglandin that doesn’t need a prescription, making it unique. In comparative testing, it caused the least eye irritation, making it a great choice for those wanting longer, healthier lashes. It also worked the best out of all other serums for our testers with aging lashes, making them stronger and grow back faster. With its effectiveness, affordability, and gentle formula, it’s a compelling option to consider trying.

#2 Latisse Lash Serum

• Efficacy: 96% of our testers reported longer lashes
• Price: $168 (the most expensive of the serums we tested)
• Aging: 3/5
• Safety: 20% of our testers reported eye irritation
• Active Ingredient: growth-enhancing prostaglandin (requires a prescription)

Overall rating: ⭐️⭐️⭐️

Latisse Eyelash Serum, ranked second-best, boasts a 96% efficacy rate for longer lashes. However, priced at $168, it is the most expensive serum among those tested. Furthermore, 20% of testers experienced eye irritation, higher than alternative serums. Despite containing a growth-enhancing prostaglandin, the need for a prescription could deter some users. While effective, its high price and potential for eye irritation make it less appealing than other options.

#3 Liquid Lash Extensions™ Lash Serum

• Efficacy: 90% of our testers reported longer lashes
• Price: $56
• Aging: 3/5
• Safety: 15% of our testers reported eye irritation
• Active Ingredient: conditioning peptides and biotin

Overall rating: ⭐️⭐️⭐️

The Liquid Lash Extensions™ Lash Serum is priced at $56 and has a 90% efficacy rate in promoting longer lashes, making it a competitive choice. However, 15% of users experienced eye irritation, which is a notable drawback. The serum stands out for its use of conditioning peptides and biotin, offering a prostaglandin-free alternative for lash enhancement. Despite its positive effects, the risk of eye irritation and slightly lower efficacy rate may make it less appealing compared to other serums.

#4 Vegamour GRO Lash Serum

• Efficacy: 70% of our testers reported longer lashes
• Price: $72
• Aging: 2/5
• Safety: 15% of our testers reported eye irritation
• Active Ingredient: strengthening red clover and mung bean

Overall rating: ⭐️⭐️

Vegamour GRO Lash Serum offers 70% efficacy for longer lashes. It is priced at $72, making it mid-range among tested serums. Like others, 15% of users experienced eye irritation, which is a drawback. Vegamour Show Lash includes red clover and mung bean for lash enhancement but with lower efficacy and potential for eye irritation, its appeal may be reduced compared to other serums.

#5 L’Oréal Paris Lash Serum Solution

• Efficacy: 30% of our testers reported longer lashes
• Price: $16
• Aging: 2/5
• Safety: 25% of our testers reported eye irritation
• Active Ingredient: strengthening amino acid arginine

Overall rating: ⭐️

L’Oréal Paris Lash Serum Solution, despite its strong brand recognition, ranks poorly due to its low efficacy rate of 30%. While priced affordably at $16, making it the most budget-friendly option among the serums tested, 25% of users experienced eye irritation. The serum contains the strengthening amino acid arginine, offering a simple approach to lash enhancement. However, its low efficacy rate, high risk of eye irritation, and lack of cruelty-free procedures make it a less effective and safe choice for individuals seeking noticeable lash growth.
