7 Best Lash Growth Serums for Healthier-Looking Lashes

Longer-looking lashes can completely change your makeup routine. You may need less mascara, skip falsies, and still get that soft, fluttery effect. That explains why lash growth serums have become so popular.

However, not every formula works in the same way. Some focus on conditioning and strengthening the lashes. Others contain peptides, botanical extracts, biotin, or growth-factor ingredients. A few formulas also contain prostaglandin analogues, which can come with additional considerations. So, choosing the right serum takes more than grabbing the most popular bottle.

You also need to think about your lash goals, sensitivity, ingredients, application routine, and patience.

If you are new to lash care, Classic Lash Extensions for Beginners: Everything You Need to Know is another helpful place to start before adding extensions to your beauty routine.

For this guide, I picked seven lash serums worth considering for different needs. Some focus on fuller-looking lashes, while others stand out for their peptide-rich or prostaglandin-free formulas.

Keep in mind that lash serums do not create overnight results. Consistent use matters, and visible changes can take several weeks. Let’s look at the formulas that deserve a spot on your radar.

7 Best Lash Growth Serums for Healthier-Looking Lashes

1. The Ordinary Multi-Peptide Lash and Brow Serum

GlowSpot

The Ordinary Multi-Peptide Lash and Brow Serum stands out if you want a lightweight peptide-focused formula.

The serum uses four peptide complexes alongside ingredients such as caffeine, panthenol, arginine, and plant extracts. The brand describes it as a water-based formula designed to support a thicker, fuller, healthier-looking appearance. It also offers a simple application routine.

The brand recommends applying a thin layer along the lash line after cleansing and drying the area. You can use it morning and evening.

That makes this a nice option for someone who wants a straightforward addition to an existing lash routine. I especially like the ingredient approach here.

Instead of relying on one standout ingredient, the formula combines several peptides with conditioning ingredients.

Best for: Beginners who want a peptide-based lash serum.

Standout ingredients: Peptides, panthenol, caffeine, arginine, plant extracts.

Why it stands out: Lightweight formula with several peptide complexes and a simple twice-daily routine.

2. Olaplex Lashbond Building Serum

Olaplex Lashbond Building Serum is another strong choice for people focused on healthier-looking lashes.

The formula uses Olaplex Peptide Complex Technology along with hyaluronic acid, biotin, panthenol, and red clover extract. The brand says the formula is designed to support the natural lash cycle while improving the appearance of dry or brittle lashes. It also does not contain prostaglandins.

That point may matter if you specifically want a prostaglandin-free formula. Olaplex recommends applying the serum twice daily before skincare and makeup. Its product information also reports visible improvements in lash appearance during a 12-week consumer study.

The texture also makes it easy to fit into a regular beauty routine. You do not need to create a complicated nighttime ritual.

Best for: People who want a prostaglandin-free, peptide-focused formula.

Standout ingredients: Peptides, hyaluronic acid, biotin, panthenol, red clover extract.

Why it stands out: Lightweight formula designed around lash conditioning and retention.

3. LashFood Phyto-Medic Eyelash Enhancer

LashFood Phyto-Medic Eyelash Enhancer is worth considering if you prefer a botanical-focused formula.

The product uses LashFood’s Phyto-Medic Complex and focuses on conditioning and enhancing the appearance of the lashes.

Allure previously highlighted this serum as a prostaglandin-free option and noted its combination of peptides and botanical extracts.

That makes it appealing if you want to avoid prostaglandin analogues. LashFood also positions the formula as a natural lash enhancer. Still, keep your expectations realistic.

Natural or botanical ingredients do not automatically guarantee faster lash growth. Instead, think of this type of serum as part of a consistent lash-conditioning routine. Your application technique matters too.

Apply only the recommended amount along the lash line. More product will not automatically create better results.

And if you are already wearing extensions, proper maintenance matters just as much as your serum routine. How Long Do Classic Lash Extensions Really Last? explains how natural lash shedding affects extension longevity.

Best for: People looking for a prostaglandin-free, botanical-focused formula.

Standout ingredients: Peptides, botanical extracts, aloe and conditioning ingredients.

Why it stands out: A good option for people who prefer a plant-focused approach.

4. RevitaLash Advanced Eyelash Conditioner

RevitaLash Advanced Eyelash Conditioner has built a strong reputation in the lash-care world.

Its BioPeptin Complex combines peptides, biotin, lipids, and green tea extract. The brand says these ingredients help condition, strengthen, and soften lashes while helping defend against brittleness and breakage.

It also contains a prostaglandin analogue called ethylcloprostenolamide. That detail deserves attention. If you specifically want a prostaglandin-free serum, this is not the formula to choose.

The brand also includes specific usage warnings and advises against use on damaged or irritated skin. So, always read the current product directions before applying it.

RevitaLash may appeal to someone who wants a well-known lash conditioner with a broader ingredient blend.

If you want more ideas for enhancing your lashes without focusing on serum alone, 15 Classic Lash Extensions for Hooded Eyes offers inspiration for different eye shapes.

Best for: People interested in a well-established lash conditioning formula.

Standout ingredients: Peptides, biotin, lipids, green tea extract.

Important note: Contains a prostaglandin analogue.

5. AnteAGE Overnight Lash Serum

AnteAGE Overnight Lash Serum takes a different approach.

The formula contains multiple growth-factor ingredients along with hyaluronic acid, botanical extracts, biotin, and antioxidants. AnteAGE describes the serum as prostaglandin-free and recommends applying it to the base of the lashes one to two times daily.

That ingredient list makes it one of the more unusual options in this roundup. Growth-factor formulas can sound complicated, but the routine itself stays simple.

Clean your lash area. Apply the serum carefully along the lash base. Then give it time. Do not expect dramatic changes after a few nights.

Lash growth takes patience, and consistent application matters more than applying a thicker layer.

This serum may appeal to someone who wants a more specialized formula and prefers to avoid prostaglandins.

If you are also curious about fuller lash styles, Hybrid Lash Extensions Explained: The Perfect Mix of Natural and Glam can help you understand another way to create a fuller appearance.

Best for: People interested in growth-factor-based formulas.

Standout ingredients: Growth factors, hyaluronic acid, biotin, botanical extracts.

Why it stands out: Prostaglandin-free formula with multiple growth-factor ingredients.

6. NULASTIN LASH Follicle Fortifying Serum

NULASTIN LASH Follicle Fortifying Serum is another interesting option for people who want a more intensive lash routine.

The formula includes Myristoyl Pentapeptide-17, glycerin, elastin, keratin, additional polypeptides, and isopropyl cloprostenate.

NULASTIN says its independent 12-week study showed improvements in the appearance of short lashes, with the brand reporting visible changes starting around six weeks.

Allure also reviewed the product and described it as a conditioning serum that can add volume and length to lashes over time.

There is one important ingredient detail to notice. NULASTIN’s current ingredient list includes isopropyl cloprostenate, a prostaglandin analogue.

That makes this a different choice from the prostaglandin-free formulas above. If avoiding prostaglandin analogues is important to you, choose another serum from this list.

If you are considering a fuller lash look through extensions instead, 15 Hybrid Lash Extension Ideas You’ll Want to Screenshot has plenty of inspiration.

Best for: People looking for a peptide and growth-factor-style lash formula.

Standout ingredients: Peptides, keratin, elastin, polypeptides.

Important note: Contains isopropyl cloprostenate.

7. Twenty/Twenty Beauty Get Growing Lash & Brow Serum

Twenty/Twenty Beauty Get Growing Lash & Brow Serum is a simpler choice for people who prefer oil-based conditioning. This formula uses a simple combination of castor oil, coconut oil, and argan oil. These oils condition and hydrate lashes rather than directly proving faster lash growth.

That distinction is important. Conditioning can make lashes feel softer and look healthier. It does not necessarily mean the product changes how quickly your lashes grow.

Still, this type of formula can work nicely for someone who mainly wants to support the appearance of dry or brittle lashes. You should still follow the product’s directions carefully around the eye area. If you enjoy the look of natural lash enhancements, Classic Lash Extensions for Beginners: Everything You Need to Know can help you understand what to expect from a classic set.

Best for: People who prefer simple, oil-based conditioning.

Standout ingredients: Castor oil, coconut oil, argan oil.

Why it stands out: Simple ingredient approach focused on conditioning.

How Do Lash Growth Serums Work?

The phrase “lash growth serum” covers several different types of formulas. Some contain peptides. Others contain botanical extracts, biotin, panthenol, oils, or growth-factor ingredients.

Some also contain prostaglandin analogues. These ingredients do not all work in the same way. Peptides often appear in lash products designed to condition and support stronger-looking lashes.

Ingredients such as panthenol and biotin can also contribute to a conditioning-focused formula. Botanical oils mainly help with moisture and softness. Many over-the-counter lash serums work more by conditioning and hydrating existing lashes, which can help them look thicker and healthier.

That is why the phrase healthier-looking lashes matters. A serum may improve the appearance of your lashes without dramatically changing their natural growth cycle. Check this out next: Volume Lash Extensions: What Makes Them Different?

What Ingredients Should You Look For?

Start by deciding what you want from your serum. If you want conditioning, look for ingredients such as peptides, panthenol, biotin, hyaluronic acid, and nourishing oils. If you want a prostaglandin-free formula, check the complete ingredient list carefully.

Do not rely only on the front of the box. Ingredient lists can change, and brand formulas can vary by region. For example, The Ordinary currently lists several peptide complexes, caffeine, panthenol, arginine, and plant extracts in its formula.

Olaplex uses a peptide complex with hyaluronic acid, biotin, and panthenol. Those examples show why comparing ingredient lists can be more useful than comparing marketing claims. If you want to compare different lash-enhancement materials, Faux Mink vs Silk Lashes: What’s the Difference? is another helpful guide.

Are Prostaglandin-Free Lash Serums Better?

“Better” depends on what you want. A prostaglandin-free formula can appeal to people who want to avoid prostaglandin analogues. Several options in this list use peptides, botanical ingredients, oils, or growth factors instead.

Olaplex, LashFood, and AnteAGE all position their lash formulas without prostaglandins. Other products on this list do contain prostaglandin analogues. RevitaLash lists ethylcloprostenolamide in its ingredients.

NULASTIN lists isopropyl cloprostenate. So, ingredient awareness matters. If you prefer a prostaglandin-free routine, stick with formulas that clearly state that they do not contain these ingredients.

How Long Does It Take to See Results?

Do not judge a lash serum after three days. That is one of the easiest ways to become disappointed. Lashes grow through natural cycles, and visible changes take time.

Consistent use for several weeks may be needed before noticeable changes, with some results becoming more apparent around 12 to 16 weeks. Some individual products publish their own study timelines. NULASTIN reports visible improvements beginning around six weeks in its 12-week study.

Olaplex reports consumer-study results across a 12-week period. The lesson is simple. Pick one formula.

Use it consistently. Take a starting photo. Then compare your lashes after several weeks. Daily mirror checks make small changes almost impossible to notice.

How to Apply Lash Growth Serum Correctly

Application does not need to become complicated. Start with a clean lash line. Remove makeup completely. Allow the area to dry.

Then apply a thin line of serum according to the product instructions. Do not flood your lash line with product. More serum does not automatically mean faster results.

The Ordinary, for example, recommends applying a thin layer along the lash line after cleansing and drying the area. Olaplex recommends applying its formula twice daily before skincare and makeup. Follow the specific directions for your product.

Different formulas can have different instructions. If you wear extensions, your lash-care routine also needs to account for the extensions themselves. Lash Extension Aftercare: The First 24 Hours Matter covers the basics.

Can You Use Lash Serum With Lash Extensions?

You may be able to use certain lash serums with extensions, but the formula and your extension routine matter. Start by checking the serum’s directions. Then consider your extension adhesive and aftercare routine.

You should also avoid rubbing your lash line during application. Extensions already require gentle handling. Adding a serum should not turn into extra tugging, brushing, or manipulation.

If your extensions start falling faster than expected, look at your daily habits first. 10 Mistakes That Make Lash Extensions Fall Out Faster explains several common mistakes that can shorten the life of your set. The goal is to support your natural lashes without creating extra stress.

Can Lash Serums Make Your Lashes Look Fuller?

Yes, some formulas can help lashes appear fuller. However, “fuller-looking” can happen in different ways. Conditioning may reduce the look of dryness and brittleness.

A healthier lash can look darker, smoother, or more substantial. Some products also claim to support visible density or length over time. The Ordinary describes its formula as supporting a thicker, fuller, healthier-looking appearance.

NULASTIN reports improvements in the appearance of lash fullness during its study period. That does not mean every person will see the same result. Your natural lash cycle, starting density, product consistency, and individual response all matter.

What If Your Lashes Are Breaking?

A serum may not solve the biggest problem if your lashes keep breaking. Look at your habits first. Do you rub your eyes? Do you sleep in mascara?

Do you yank off strip lashes? Do you aggressively curl your lashes? Do you pull at grown-out extensions? Those habits can undo the benefits of a careful lash routine.

Try reducing the physical stress on your lashes before adding more products. If you wear false lashes regularly, Common Strip Lash Mistakes and How to Avoid Them can help you spot habits that may contribute to breakage. Healthy-looking lashes need gentle handling as much as they need good products.

Should You Use a Lash Serum Every Day?

Most lash serums work best when you follow their specific application schedule. Some require once-daily use. Others recommend twice-daily application.

The Ordinary currently recommends morning and evening use. Olaplex also recommends twice-daily application. NULASTIN recommends twice-daily use as part of its routine.

That does not mean every serum requires the same schedule. Follow the instructions for the exact product you purchase. If you want a fuller look without daily mascara, 20 Volume Lash Ideas for a Full, Fluffy Look offers plenty of lash inspiration.

Some contain growth-factor ingredients. A few contain prostaglandin analogues. That makes ingredient checking especially important.

For a simple peptide option, The Ordinary is a strong starting point. Olaplex works well for someone looking for a prostaglandin-free peptide formula. LashFood suits people who
