Most people who reach for a lash serum have already tried the drugstore route. Maybe the lashes still feel stubby after mascara, or the brow gaps show through every selfie. The right serum works with your natural growth cycle, which is why the picks below focus on formulas, applicators, and ingredient profiles that suit different routines and sensitivity levels.
A Fast Comparison Of The Options
TOPLASH Eyelash Growth Serum for Brows & Lashes, 0.10 fl.oz.
Babe Original Renewing Lash Serum with Peptides
NULASTIN Follicle Fortifying Eyelash Serum, 0.1 oz
MAREE Eyelash Serum for Lashes & Brows, Prostaglandin-Free
Stacy Lash Korean Lash Serum for Growth, 5ml
What Each Pick Brings To The Table
TOPLASH earns its spot as the entry point for anyone dipping a toe into lash serums. The slim 0.10 fl.oz. tube fits into a crowded bathroom drawer, and the brush-style applicator mirrors the kind of tool you already use for liquid liner, so the first application feels familiar.
The formula is hypoallergenic and cruelty-free, which matters if your eyes sting easily or you prefer gentler actives. Where the Babe Original leans on peptides and NULASTIN focuses on follicle support, TOPLASH takes a softer route, making it a sensible first purchase before graduating to heavier-hitting options.
Where It Delivers
- Cruelty-free and hypoallergenic profile for cautious users
- Dual-purpose applicator handles both lashes and brows in one stroke
- Compact 0.10 fl.oz. size is travel-friendly and won’t dry out before you finish it
- Beginner-friendly applicator design lowers the learning curve
Things To Consider
- The smaller bottle may run out before you see peak results on longer hair cycles
- Owners with very sparse brows sometimes find the brush slightly wide for tight gaps
Who It Suits Best
First-time serum shoppers who want a low-commitment introduction and a formula easy on reactive eyes.
Look Elsewhere When
You’d rather invest in a peptide-led, clinically tested formula, in which case the Babe Original Renewing Lash Serum suits that profile more directly.
The Babe Original formula stands out for leaning on peptides, which are short chains of amino acids that support the keratin structure of each lash. If you’ve watched lashes feel brittle after extensions or over-plucking, peptide-based care targets that fragility from a different angle than the gentler TOPLASH formula.
Where the NULASTIN pick doubles down on follicle fortification, Babe Original keeps the routine more streamlined: one tube, one brush, nightly application. The brand is well established in the category, and that maturity shows up in how predictably the serum layers under makeup without flaking or pilling at the root.
Real Benefits
- Peptide-driven formula supports lash strength from the keratin level
- Sensitive-eye friendly application for contact lens wearers
- Works cleanly under mascara without residue or flaking
- Established brand track record in the lash care category
- Layerable into nightly routines without disrupting serum absorption
Worth Noting
- Peptide-based serums typically need a longer runway before visible results show, so patience matters
- Those seeking a dual lash-and-brow formula may want a separate brow product
Key Product Details
Made For
Anyone with brittle or post-extension lashes who wants a peptide-led serum and tolerates a longer ramp-up period.
Consider Something Else When
You want follicle-level fortification for sparse lashes, where the NULASTIN Follicle Fortifying Eyelash Serum is the more targeted option.
NULASTIN approaches the lash cycle from the follicle side, which is the small pocket where each lash is anchored. If your main frustration isn’t length but fallout, the fortifying angle here is worth attention, and the brand markets the serum for both women and men, which broadens the appeal.
Compared to the smooth, makeup-friendly Babe Original, NULASTIN reads as more of a treatment step. You’ll typically apply it at night on a clean lash line, and the result is a routine that feels closer to skincare than cosmetic. For shoppers who’ve tried peptide serums without much change, that shift in approach can be the missing piece.
Strong Points
- Follicle-focused formula targets the root where premature shedding starts
- Suitable for both men and women dealing with thinning or sparse lashes
- Non-invasive alternative to in-office lash treatments
- Pairs naturally with evening skincare routines
Trade Offs
- Follicle-targeted care requires consistent nightly use before payoff shows
- Treatment-step feel may feel heavier than a makeup-layering serum like Babe Original
- Smaller 0.1 oz bottle means reordering frequency is higher for long-term users
Feature Snapshot
Right Fit For
Shoppers with sparse or shedding lashes who want a follicle-focused routine and don’t mind a treatment-step feel.
A Better Fit Elsewhere
You’d rather layer serum under mascara in the morning, in which case the Babe Original Renewing Lash Serum fits that daily-makeup lifestyle better.
Prostaglandins are a class of synthetic compounds sometimes linked to irritation or unintended darkening around the lash line. MAREE skips that category entirely, making this serum a common pick for shoppers who read ingredient lists closely or have had bad reactions elsewhere on the list.
The formula is designed to work on both lashes and brows, similar to the TOPLASH dual-purpose design, but with hyaluronic acid and conditioning oils in the mix. Compared to the follicle-targeted NULASTIN, MAREE reads as more of a daily conditioning serum than a corrective treatment.
Points In Its Favor
- Prostaglandin-free formulation for ingredient-conscious shoppers
- Works across both lashes and brows in a single routine
- Hyaluronic acid base adds a conditioning, hydrating feel
- Gentle enough for daily layering around sensitive eyes
- Oil-based texture suits dry skin and brow areas
Soft Spots
- Conditioning focus means visible thickening may take longer than follicle-targeted serums
- Oil-rich texture can feel slick on oily skin types in humid climates
Who Should Grab It
Anyone avoiding prostaglandins or with sensitive eyes who wants a daily conditioning serum for both lashes and brows.
Swap It Out When
You specifically need a follicle-strengthening treatment for shedding, where NULASTIN’s targeted approach fits better.
The Stacy Lash serum stands out for sheer volume. At 5ml, it outpaces the 0.10 oz (roughly 3ml) and 0.1 oz bottles from TOPLASH and NULASTIN, which makes it a natural fit for daily users who don’t want to reorder every few weeks.
Korean beauty formulas often lean on multi-peptide complexes, and the brand positions this serum for both lashes and brows. Where the MAREE pick focuses on gentle conditioning and the Babe Original keeps things peptide-led, Stacy Lash splits the difference with a multi-zone bottle aimed at consistent long-term users.
Everyday Perks
- Larger 5ml size suits daily, long-term routines
- Multi-peptide blend supports both lash and brow fullness
- Workhorse bottle for households sharing one product
- Compatible with morning or evening routines
Honest Caveats
- Bigger bottle takes longer to finish, so storing it away from humidity matters for shelf life
- Multi-peptide approach may feel less targeted than NULASTIN’s follicle-specific angle
Feature Rundown
Best Suited To
Daily users with both lashes and brows in their routine who want a higher-volume peptide serum without reordering constantly.
Reach For A Different Pick When
You have reactive eyes and want the gentlest possible intro, where TOPLASH Eyelash Growth Serum’s hypoallergenic build is the safer start.
Choosing A Lash Serum That Actually Fits Your Routine
The first thing to look at is the active category, since this decides what kind of results you can expect. Peptide complexes, like the ones in Babe Original and Stacy Lash, work on the keratin structure of each lash and tend to favor strength and visible thickness. Follicle-focused formulas, such as NULASTIN, target the root where each lash is anchored and tend to suit people dealing with fallout more than length. Conditioning serums like MAREE lean on hydrating ingredients for a gentler daily feel.
Consider your sensitivity profile. Prostaglandin-free options exist for shoppers who want to avoid that class of compounds, and hypoallergenic formulas help contact lens wearers and anyone with reactive eyes. If you’ve had irritation from beauty products in the past, start with the gentlest option before graduating to peptide-led formulas.
Your applicator matters more than people expect. A fine brush gives precise line work for tight gaps, while a wider applicator covers more area in one stroke. The dual-purpose picks (TOPLASH, MAREE, Stacy Lash) work for both lashes and brows, which simplifies the routine if you treat both zones.
The bottle size ties into your commitment level. Smaller 0.1 oz bottles suit short trial periods, while the 5ml Stacy Lash fits daily users who don’t want to reorder every few weeks. For most routines, expect at least six weeks of consistent use before evaluating the results, since lash growth cycles run on their own clock.
Where Shoppers Slip Up
Wrong Turns To Avoid
Buying based purely on the strongest claim. A serum that promises dramatic change in two weeks often relies on coating agents that wash off, not on real follicle support. The more honest serums on this list position themselves around consistent use and realistic timelines.
Skipping patch testing. Even gentle formulas can react with specific skin chemistry, so a small test along the lash line for a few days helps avoid full-face irritation if you turn out to be sensitive to an ingredient.
Mixing two serums at once. Layering two actives on the same lash line can dilute both and increase the chance of irritation. Pick one serum and give it a full cycle before deciding whether to switch.
When Paying More Pays Off
Premium-positioned serums typically invest in clinical testing, cleaner ingredient sourcing, and applicator precision. The higher tier earns its place when the formula has documented testing behind it, the applicator delivers consistent dosing, and the ingredient list is fully disclosed. For casual users, a gentler starter like TOPLASH covers the basics well. For committed users who want a peptide-led or follicle-targeted routine, the higher-tier picks tend to deliver more predictable results over a longer timeline.
Frequently Asked Questions
How long does a lash serum take to show visible results?
Most lash serums need at least six to eight weeks of nightly use before visible changes appear, since natural lash growth cycles run roughly that long. Faster claims usually refer to coating or conditioning effects rather than true length changes.
Can lash serums be used on brows too?
Several formulas on this list, including TOPLASH, MAREE, and Stacy Lash, are designed for both lashes and brows. The application technique is the same, though you may want a lighter hand on brows to avoid product migrating into the hairline.
Are lash serums safe for sensitive eyes?
Prostaglandin-free and hypoallergenic formulas like TOPLASH and MAREE tend to suit sensitive eyes best. Patch testing along the outer lash line for a few days before full application is still a smart precaution.
Do lash serums cause darkening around the eye?
Some prostaglandin-based formulas have been associated with darkening of the lid or iris. The prostaglandin-free options on this list are designed to avoid that side effect, though individual reactions can still vary.
What happens if you stop using a lash serum?
Once you stop applying, your lashes gradually return to their natural growth cycle. There’s no withdrawal effect, but the visible benefits from consistent use tend to fade over several weeks without continued application.
The Takeaway
Your best pick depends less on hype and more on what your lashes actually need right now. Sensitive eyes and first-timers get a low-commitment start with TOPLASH, peptide shoppers land on Babe Original, and follicle-conscious routines find their match in NULASTIN. Anyone avoiding prostaglandins or running a daily dual-zone routine will find a sensible home with MAREE or Stacy Lash. Pick the formula that fits your eyes and your habits, then give it the full growth cycle before judging the results.
