Top 10 Lash Serum Reviewed
1. ForChics Lash Serum
$24 (Regular $39) - Only $0.10 per application
(OUR TOP PICK!)
★★★★★ Emma S. (37) Verified
"I was skeptical at first, but the difference is undeniable! It's only been a month and my lashes are noticeably thicker and longer. I feel so much more confident without mascara!"
★★★★★ Sophia L. (26) Verified
"Finally, a serum that lives up to its promises! My lashes were always brittle and short, but after using ForLash for just a few weeks, they've transformed. They're not only longer, but stronger and healthier looking."
★★★★★ Ava J. (32) Verified
"I've tried every lash enhancer out there, but this one is a game changer. I saw visible improvements in just under three weeks, and I love how my lashes now frame my eyes. Big thanks to ForLash!"
The ForChics Lash Serum stands out as our clear winner, offering the ideal combination of safety, effectiveness, and value. What sets this serum apart is its clean, hormone-free formula that delivers visible results without the dangerous side effects plaguing most competitors.
Unlike other serums that rely on risky prostaglandin analogs, ForChics uses a powerful blend of well-known peptides, vitamins, and botanical extracts. You'll see visible improvements in just 27 days, with up to 55% longer and 75% more voluminous-looking lashes by 8-12 weeks.
At only $0.10 per application, ForChics offers exceptional value compared to competitors charging $0.30-$1.50 per use. Plus, their genuine 12-week money-back guarantee gives you complete peace of mind.
Pros:
- Hormone-free, clean formula with no prostaglandin analogs
- Visible results in 27 days, full transformation in 8-12 weeks
- Up to 55% longer and 75% more voluminous lashes
- Compatible with extensions and contact lenses
- 12-week money-back guarantee
- Only $0.10 per application (exceptional value)
- Easy 5-second application
- Made in USA with clean, vegan ingredients
Cons:
- Results require patience and consistency (8-12 weeks for full transformation)
- High demand sometimes causes temporary stock shortages
- Only available through ForChics website
2. Rodan and Fields Lash Boost
$122- $153
★★★★★ Molly Verified
"It WORKS … takes ~4 weeks to see a big difference … the only product that actually lengthens my lashes."
★★★★☆ Kate Verified
"100% works … but use with caution! It has an ingredient that can cause fat loss and discoloration… It just causes an indent … where you apply the serum"
★☆☆☆☆ Jeanna Verified
"Not worth it. It did not make any improvements to my skin. If anything, I feel like the pores in my cheeks have gotten larger since I started using this device."
The Rodan and Fields Lash Boost sits at #2 due to its effectiveness, but comes with serious safety concerns that keep it from the top spot. While many users report visible lash growth within 4-6 weeks, the serum contains isopropyl cloprostenate (a synthetic prostaglandin analog that has led to class action lawsuits).
In 2018, Rodan & Fields paid $38 million in settlements over failure to disclose the risks of their prostaglandin analog ingredient. Users have reported serious side effects including iris discoloration, droopy eyelids, permanent darkening of skin around the eyes, and even vision changes.
At $122-153, it's also significantly more expensive than safer alternatives, and the MLM business model adds another layer of concern for many consumers.
Pros:
- Many users see visible results within 4-6 weeks
- 60-day money back guarantee
- Compatible with contact lenses
Cons:
- Contains dangerous prostaglandin analog (isopropyl cloprostenate)
- $38 million class action settlement for eye damage
- Serious side effects: iris discoloration, droopy eyelids, darkening
- Very expensive ($122-153 vs ForChics $24)
- MLM business model concerns
- Not recommended for lash extensions
- No long-term safety testing
3. Vegamour GRO Lash Serum
$57- $68
★★☆☆☆ Sarah b. Verified
"I dont like this brand… My hair is fluffy and dry after using."
★☆☆☆☆ Lynelle, Verified
"Do not buy from this Company!! They Charge you to Cancel a Subscription that you didn't sign up for."
★★★★☆ Reddit User Verified
"Overall, I would absolutely recommend this to anyone looking to see relatively quick growth with their lashes! Consistency is key, but it's easy to use."
Vegamour positions itself as a clean, vegan alternative to prostaglandin-based serums, which sounds appealing in theory. However, the reality is far more problematic. While the hormone-free formula is safer than competitors using prostaglandin analogs, the results are significantly weaker and inconsistent.
The biggest red flag with Vegamour isn't the product itself, but their predatory business practices. Countless customers report being trapped in unwanted subscriptions, charged without consent, and facing extreme difficulty canceling orders. Their customer service has earned terrible reviews across multiple platforms.
Even when the product works, results are modest at best, taking 4-8 weeks to see minimal improvements that many users describe as barely noticeable.
Pros:
- Clean, vegan, hormone-free formula
- No prostaglandin analog risks
- Some users report gentle conditioning effects
Cons:
- Subscription trap (extremely difficult to cancel)
- Auto-billing without clear consent
- Weak, inconsistent results compared to alternatives
- Many users report no visible improvement
- Poor customer service ratings
- More expensive than ForChics with inferior results
4. Diablo Cosmetics Eyelash Serum
$28 (Regular $56)
★★★★★ Denise Verified
"I thought I would try the Eyelash Serum … I have used the serum every night for the past 4 weeks. After two weeks … I was surprised to see a noticeable difference … my partner commented … I knew it was working!"
★☆☆☆☆ E. N. Verified
"I ordered a lash serum … every time I tracked the status, it did not change. I have no idea where is my package … I started to doubt the quality of the products too."
★☆☆☆☆ Rachel GB Verified
"Eyelash serum took well over 2 weeks to arrive … the 'serum' is much more like water than serum … the wand is cheap … I could not recommend this eyelash serum, on any level."
Diablo Cosmetics appears attractive at first glance with its low price point and bold claims of "50% longer lashes in 30 days." However, this serum is plagued by quality control issues and questionable business practices that make it a risky choice.
The biggest concern is that products ship from China with inconsistent quality with many users reporting receiving tubes that are half-empty, watery consistency instead of serum, and damaged packaging. The "regular price" of $56 appears to be artificially inflated to make the $28 "sale price" seem like a deal.
While the ingredient list looks decent on paper, the execution falls short with numerous complaints about delivery delays, poor packaging, and a product that feels more like water than a conditioning serum.
Pros:
- Lower price point than most competitors
- Claims to be hormone-free and vegan
- Oil-free formula (extension compatible)
- 60-day money-back guarantee
Cons:
- Ships from China with quality control issues
- Inflated "regular" pricing ($56 → $28 fake discount)
- Watery consistency - many report half-empty tubes
- Poor packaging and shipping delays
- Aggressive timeline claims without proper backing
- Customer service difficulties
- No clear third-party safety testing
5. Levaye Show Lash Serum
$60 - $93
★★★★★ Cynthia Verified
"Great service was delivered fast. I love the product — my eyelashes look fake they are so long."
★☆☆☆☆ Den Matte Verified
"SCAM — Lashella or whoever they claim to be don't exist. Don't give them any money as they don't have any products. All communication ignored and no refund given."
★☆☆☆☆ Lucy Verified
"I have been using the product for 2 weeks. It has made no difference and it has given me a stye on my eye. Do not buy! It is a waste of money!"
Levaye markets itself as having the "same main ingredient as prescription medication" which should immediately raise red flags. This means they're using a prostaglandin analog (Methylamido Dihydro Noralfaprostal), putting users at risk for the same serious side effects as prescription treatments.
The pricing is also concerning, with a "regular" price of $93 marked down to $60 (a common tactic to create false urgency). More troubling are the numerous complaints about non-delivery, poor customer service, and users developing styes and eye irritation.
The 60-day guarantee sounds good in theory, but multiple reviewers report difficulty getting refunds or even responses from customer service.
Pros:
- Uses recognized prostaglandin analog for potential effectiveness
- 60-day money-back guarantee (if honored)
- Claims compatibility with extensions and contacts
- Made in USA
Cons:
- Contains prostaglandin analog with serious side effect risks
- Users report styes, irritation, and eye problems
- Poor customer service and refund difficulties
- Inflated pricing scheme ($93 → $60)
- Multiple complaints of non-delivery
- Requires continued use to maintain results
- Not suitable for pregnant/nursing women
6. Lilash Purified Eyelash Serum
$90
★★★★★ Kim Townsend Verified
"Best lash serum on the market … I get the best results without irritation."
★★★★☆ SH Verified
"Waste of your effort, time and $'s … The company say money back guarantee if it doesn't work after 90 days, but, what they don't say is, it runs out after 60 days!"
★☆☆☆☆ Reddit User Verified
"They aren't good for eye health. They block your eyelid's oil glands which causes red painful lumps … after using one for three weeks … blepharitis for about three months."
Lilash has been around for years and built a reputation in the lash serum space, but recent regulatory scrutiny has revealed serious concerns. The serum contains dehydrolatanoprost, another prostaglandin analog that carries the same risks as other hormone-based formulas.
Most concerning is that Lilash has been banned or flagged by regulatory authorities in some jurisdictions, including warnings from Australia's Therapeutic Goods Administration (TGA) due to safety concerns. The brand's TrustPilot rating of just 2.2/5 reflects widespread customer dissatisfaction.
At $90 for a 2mL tube, it's expensive for what you get, and the "90-day guarantee" has been criticized by users who claim the product runs out before the guarantee period ends.
Pros:
- Established brand with some positive user reports
- Physician-formulated claims
- 90-day money-back guarantee (with limitations)
- Detailed application instructions
Cons:
- Contains prostaglandin analog (dehydrolatanoprost)
- Banned/flagged by regulatory authorities (Australia TGA)
- Very poor TrustPilot rating (2.2/5 stars)
- Users report blepharitis and blocked oil glands
- Expensive at $90 for 2mL
- Guarantee issues - product runs out before 90 days
- Poor customer service reviews
- Risk of counterfeit products due to popularity
7. Nulastin LASH Follicle Fortifying Serum
$71 - $84
★★★★★ Judge.me Site Review
"I noticed visible results within a few weeks of using it, and have had lasting results."
★☆☆☆☆ IOnlySpeakBroke Verified
"Worst irritation, surplus of milia in water line, and darkening + hollowing of eyes. I have used a large variety of lash serums … I have never had worse irritation and side effects than Nulastin … within days … 2-3 milia on my waterline per eye … lids would often burn … lids have also darkened …"
★★☆☆☆ Sitejabber Overall Verified
2.4/5 stars from 103 reviews
Nulastin markets itself with impressive claims like "100% saw improvement" and "97% noticed faster growth," but these statistics come from a small, brand-conducted study with questionable methodology. More telling is their overall brand rating of just 2.4/5 stars on Sitejabber.
The serum contains isopropyl cloprostenate, the same dangerous prostaglandin analog found in other problematic serums. Users report severe side effects including milia (white bumps), eyelid burning, permanent darkening, and "hollowing" of the eye area.
At $84 for a tube that lasts only 5-6 weeks, it's also one of the most expensive options per application, making it poor value even if it worked safely.
Pros:
- Advanced ingredient mix with peptides and elastin
- Clear usage instructions and warnings
- Subscription options available
- Some users report visible improvements
Cons:
- Contains dangerous prostaglandin analog (isopropyl cloprostenate)
- Severe side effects: milia, burning, permanent darkening
- Very poor brand rating (2.4/5 on Sitejabber)
- Expensive ongoing cost ($84 every 5-6 weeks)
- Risk of permanent eye area changes
- Twice daily application required
8. Uklash Lash Serum
$32 - $49
★★★★★ Tihena Karim Verified
"Unfortunately I did not read the product description before placing an order whereby it advises against use if you are pregnant/nursing. I emailed UKLash and received a swift response from Carrie."
★☆☆☆☆ Lorraine Jones Verified
"This does not work, I fell for the false and misleading adverts for this, I used it everyday … cost £40, absolute rubbish don't buy."
★★☆☆☆ Mrs T Verified
"The brow serum works and does what it says. I have a thyroid condition and experienced a bad reaction to the prostaglandin analogue ingredient and had to stop using it."
Uklash positions itself as a more affordable option with bold claims of "85% longer and 80% fuller-looking lashes in 25 days." However, these impressive statistics are based on a tiny 4-week study with only 50 participants (hardly enough to validate such dramatic claims).
The serum contains a prostaglandin analog, which the brand acknowledges by offering a separate "Sensitive" formula without it. This admission essentially confirms they know their main product can cause reactions. Users with medical conditions like thyroid issues report particularly severe reactions.
Quality control is another major concern, with multiple complaints about faulty packaging, leaking tubes, and defective lids that render the product unusable.
Pros:
- Lower price point than premium competitors
- Offers prostaglandin-free "Sensitive" version
- 12-week money-back guarantee
- Claims compatibility with extensions and contacts
Cons:
- Contains prostaglandin analog with known side effect risks
- Packaging quality control issues (leaking tubes, faulty lids)
- Bold claims based on tiny study (50 participants, 4 weeks)
- Many users report no results despite consistent use
- Medical condition patients report severe reactions
- Mixed reviews on effectiveness
- No independent third-party validation
9. Grande Cosmetics GrandeLASH-MD
$57 - $68
★★★★☆ Reddit User Verified
"I got amazing results from Revitalash, though it's expensive as hell."
★☆☆☆☆ Reddit User Verified
"It turned my eyelids along the lash line a dark purple after just one use, and took over a week to return to normal."
★★☆☆☆ Sephora Review Verified
"My lashes did get a bit longer but definitely not worth it whatsoever. I learned that this stuff can make your under eye fat thin out …"
Grande Cosmetics has built a strong marketing presence, but user experiences reveal disturbing side effects that go beyond typical irritation. The serum contains isopropyl cloprostenate, and users report alarming changes including under-eye fat loss, premature aging of the eye area, and permanent darkening.
The most concerning reports involve "prostaglandin-associated periorbitopathy," a condition where the fat cells around the eyes shrink, creating a sunken, aged appearance that may be permanent. Multiple users describe looking older after extended use.
While some users do see lash growth, the potential for permanent facial changes makes this a high-risk choice, especially when safer alternatives like ForChics deliver similar results without the dangers.
Pros:
- Some users report visible lash growth
- 90-day return policy
- Made in USA
Cons:
- Contains dangerous prostaglandin analog (isopropyl cloprostenate)
- Users report under-eye fat loss and premature aging
- Permanent darkening of eyelid area
- "Sunken eyes" appearance from long-term use
- Purple discoloration after single use (some users)
- Expensive with potential for permanent damage
- Results disappear when discontinued
10. Revitalash Advanced Eyelash Conditioner
$100 - $152
★★★★★ Ros Roberts Verified
"Revitalash is a game changer! My lashes are noticeably longer, fuller, and healthier since I started using it. No more need for extensions …"
★☆☆☆☆ Sian Verified
"It used to work but it doesn't now. I started using this product years ago … absolutely useless, definitely doesn't work."
★☆☆☆☆ Ellen Pitt Verified
"It is quite obvious … this company charges a lot of money for a product which really has NO guarantees …"
Revitalash rounds out our top 10 as the most expensive option, with their 6-month supply costing a staggering $152. While the brand has been around for years and built name recognition, the high price doesn't translate to superior safety or results.
Like most competitors, Revitalash contains a prostaglandin analog (cloprostenol ethyl amide) that carries the same risks of irritation, darkening, and eye area changes we've seen with other hormone-based serums. The brand openly warns of potential side effects including "darkening of the lash line skin, dry eyes, eyelash loss" in their own materials.
At $152 for 6 months, you're paying premium prices for the same risks and variable results found in cheaper alternatives. When safer, more effective options like ForChics cost just $24, Revitalash's pricing becomes impossible to justify.
Pros:
- Established brand with some positive reviews
- Advanced formulation with peptides and botanicals
- 90-day return policy (in some regions)
- Ophthalmologist developed claims
Cons:
- Most expensive option ($100-152 vs ForChics $24)
- Contains prostaglandin analog (cloprostenol ethyl amide)
- Brand admits risks: darkening, irritation, lash loss
- Results revert when discontinued
- Variable effectiveness - many report no results
- Premium price doesn't equal premium safety
- Limited guarantee availability (region-dependent)

Top Considerations When Choosing An Eyelash Growth Serum:
1. Ingredient Safety:
This is the most critical factor when selecting a lash serum. Many products contain prostaglandin analogs - synthetic compounds that can cause serious side effects including permanent iris color changes, eyelid darkening, fat loss around the eyes, and even vision problems. As we've seen in our reviews, brands like Rodan & Fields have paid millions in settlements over these risks. Look for hormone-free, peptide-based formulas like ForChics that deliver results through safe, well-known ingredients.
2. Results Timeline and Realistic Expectations:
Be wary of serums promising "overnight miracles" or dramatic changes in just days. Healthy lash growth takes time. The most effective serums show visible improvements around 3-4 weeks, with full results in 8-12 weeks. ForChics' timeline of visible results in 27 days and full transformation in 8-12 weeks represents realistic, achievable expectations based on natural lash growth cycles.
3. True Value vs. Hidden Costs:
Don't be fooled by low upfront prices that hide expensive ongoing costs or subscription traps. Calculate the real cost per application. ForChics at $0.10 per application offers exceptional value compared to competitors charging $0.30-$1.50 per use. Also watch for inflated "regular" prices that make fake sales seem attractive.
4. Money-Back Guarantees That Actually Work:
Many brands offer guarantees with so many loopholes they're essentially meaningless. Look for companies that offer genuine, no-hassle refunds with reasonable timeframes. ForChics' 12-week guarantee gives you enough time to see full results while providing real protection.
5. Customer Service and Business Practices:
Avoid brands with subscription traps, poor customer service, or overseas shipping issues. Choose companies with transparent business practices, US-based operations, and responsive customer support. The number of complaints about Vegamour's subscription traps and Diablo's shipping problems should be major red flags.
6. Compatibility and Safety Testing:
If you wear contact lenses or have lash extensions, ensure the serum is specifically tested for compatibility. Look for products that have proven record, not just marketing claims.
Conclusion
Choosing the right lash growth serum is crucial for achieving your beauty goals safely and effectively. While the market is flooded with options making bold promises, our comprehensive review reveals that most serums come with significant risks, inflated pricing, or questionable business practices.
The ForChics Lash Serum clearly outshines the competition with its unique combination of safety, effectiveness, and value. As the only hormone-free option that delivers awesome results, ForChics offers the perfect solution for women who want naturally longer, fuller lashes without compromising their health or budget.
Whether you're tired of daily mascara struggles, frustrated with expensive salon treatments, or concerned about the safety risks of prostaglandin-based serums, ForChics provides the clean, effective alternative you've been searching for. With visible results in just 27 days and a genuine 12-week guarantee, it's the smart choice for your lash enhancement journey.
