Every woman knows the difference long, full lashes can make to our appearance. And while "glue-ons" may look great in the moment, wouldn’t we all prefer to grow our own stunning natural lashes?

Lash serums offer a long-term solution for women who want to help their natural lashes flourish—and break free from the constant falsies, extensions, and heavy mascara.

“Using a high-quality lash serum will actually help you (support) your own longer, thicker, denser-looking lashes so that you don’t have to use those quick fixes anymore," says Master Cosmetologist Beverley Simmons.

But, with so many empty promises in the cosmetics industry, it’s hard to know which lash serums will deliver visibly longer, thicker lashes... and which will leave you disappointed. That’s why Her Beauty Reviews has compiled the available research so you know what to look for in a quality lash serum that delivers results. 

For each product, we created a comprehensive score that considers a few different metrics, namely ingredient quality, safety, return policies, customer satisfaction, and analyzed effectiveness.

First, here's a side-by-side comparison of how industry-leading lash serums stack up against each other.

1. MUSKD™ Lash Enhancer^[1]

by MUSKD

PROS

• 3 clinically studied ingredients
• Naturally derived formula
• Acetyl tetrapeptide
• Biotinoyl tripeptide
• Red clover extract
• Amino acids

A+

OVERALL GRADE

The Bottom Line

Muskd™ Lash Enhancer stood head and shoulders above the rest.

The first thing that caught our eye (pun intended) about MUSKD™ Lash Enhancer was its advertised 99% success rate, with 61% eyelash growth within 6 weeks. With a big promise to fulfill, we headed over to the user reviews and were impressed again.

Even users with damaged or thin lashes saw big improvement, as MUSKD has a repair serum as part of its recipe. Its ingredient list is paraben-free, gluten-free and vegan, and you’ll find ginseng, herb extracts (including Ganoderma sinensis and ligustrum lucidum), tocopherol, biotin, and vitamin E in its recipe.

Analysis uncovered that most users are more than satisfied with the results, reporting fuller and longer lashes in as little as 30 days. The lashes tend to come in lush and dark, and the product itself only takes about 5 seconds to apply making it quick and easy even for the clumsiest hands.

Lunar Lash by Tru Alchemy ranks #2 on our list of top five lash serums. This PM lash serum delivers potent conditioners to help maintain hydration and support a longer, fuller look.

Lunar Lash is formulated with three clinically studied ingredients, including two peptides. It also contains clean ingredients like amino acids, hydrolyzed keratin, biotin, and panthenol that work to visibly improve lash length and volume.

Plus, Tru Alchemy’s risk-free return policy includes a 60-day, no-questions-asked guarantee. It may not be needed, however, as the effectiveness of the product earned a top score.*

3. Gro+ Advanced Lash Serum ^[1]

by Tru Alchemy

PROS

• 2 clinically studied ingredients
• Naturally derived formula
• Acetyl tetrapeptide
• Biotinoyl tripeptide
• Red clover extract
• Amino acids
• Hydrolyzed keratin
• Biotin & Panthenol
• Prostaglandin-free
• Paraben-free
• 90-day return policy

CONS

• Only 3ml of product per tube
• Can only be used at night
• Lacks hydrolyzed keratin and biotin
• Lacks amino acid complex

B+

OVERALL GRADE

The Bottom Line

There's a lot to like about GRO+ Advanced Lash Serum by Vegamour. Like most contenders on our list, this serum is made with naturally derived ingredients, and is 100% vegan and cruelty-free.

In addition to a clinically studied peptide, Vegamour's formula also includes red clover, mung bean, and hemp-derived cannabidiol, which has been shown to help support blood circulation.

Unfortunately, it lacks essential nutrients like keratin, biotin, and an amino acid complex. Their tube only contains 3ml of product and can only be used at night.

On the plus side, people who used this product left highly favorable reviews, and many people found it to be an effective lash serum. Additionally, Vegamour offers a solid 90-day money-back guarantee.

4. GrandeLASH-MD ^[1]

by Grande Cosmetics

PROS

• Panthenol
• Comprehensive amino acid complex
• Glycosaminoglycans
• Paraben-free
• 90-day return policy

CONS

• Only 4ml of product
• Can only be used at night
• Lacks peptides, keratin, and biotin
• Contains prostaglandins

B-

OVERALL GRADE

The Bottom Line

GrandeLASH-MD's award-winning lash serum is infused with a potent blend of ingredients to help promote the appearance of longer, thicker lashes. Its formula includes panthenol, amino acids, and other lash-supporting ingredients.

However, it's also missing a lot of key ingredients: peptides, biotin, and hydrolyzed keratin. And unfortunately, GrandeLASH-MD's formula contains a prostaglandin analog, which may be responsible for some users reporting discoloration around their eyes after use.

Their formula comes in 2 different sizes, the larger containing 4ml of product, which still falls short of our top pick. Plus, it's only a night time serum. Grande Cosmetics offers a 90-day return policy if you're not 100% satisfied with their product or experience adverse side effects.

5. Lash Boost ^[1]

by Rodan + Fields

PROS

• 2 peptides
• Hydrolyzed keratin, panthenol, and biotin
• 5ml of product
• 60-day guarantee
• Paraben-free

CONS

• Can only be used at night
• Lacks several key ingredients
• Contains a prostaglandin analog
• High price point at $155

C

OVERALL GRADE

The Bottom Line

Coming in at #5 is Rodan + Fields Lash Boost. Their formula includes favorites like panthenol, keratin, and biotin. However, it's missing other important ingredients like peptides and amino acids.

More importantly, Rodan + Fields recently came under fire for "deceptive labeling" and a lawsuit was filed on behalf of consumers, alleging a "failure to disclose the harmful side effects" of a prostaglandin analog in their formula.

Additionally, Rodan + Fields Lash Boost costs $155, which is 2-3 times as much as the average eyelash serum. On the upside, it does contain 5ml of product per tube. And if you're not satisfied with this product, Rodan + Fields offers a 60-day money-back guarantee.

6. Babe Lash

by Babe Original

PROS

• Biotin & panthenol
• Paraben-free
• Silk amino acids
• Green tea extract
• 90-day online return policy

CONS

• Contains synthetic prostaglandin
• 2ml of product
• AM formula sold separately
• Can only be used at night
• Lacks keratin and red clover extract

C-

OVERALL GRADE

The Bottom Line

Rounding out our list is Babe Lash. This award-winning serum is formulated with peptides, biotin, silk amino acids, panthenol, and green tea extract to help lengthen and condition lashes.

However, it falls short in a few important categories. Most importantly, Babe Lash contains a prostaglandin analog, which has been linked to negative side effects, including discoloration around the eyes.

Secondly, their formula lacks keratin and red clover extract, which are important components of a high-quality lash serum. Although they offer both an AM and a PM formula, the two are sold separately—for a steep total of $88. However, Babe Lash offers a 90-day return policy for online purchasers, which shows they stand behind their product.
