Key Takeaways

• The Trybello 2-in-1 Eyelash Growth Serum, Borboleta Lash Serum, and Vegamour GRO Lash Serum are among the highest-rated options for volume.
• Trybello 2-in-1 Eyelash Growth Serum combines a growth serum and volumizing mascara in one product. It is a clean, prostaglandin-free formula, free of oils, hormones, silicones, parabens, perfumes, and PEGs, and is backed by a 60-day growth guarantee with free worldwide shipping.

The Best Lash Serums for Volume That Actually Work

What makes a lash serum genuinely volumizing, rather than simply lengthening, comes down to the active ingredients.

Serums that extend the anagen (growth) phase of the lash cycle while simultaneously conditioning the follicle produce lashes that grow in thicker and fuller, not just longer. Most volumizing lash serums contain ingredients such as peptides, biotin, and plant-based ingredients.

Below, you’ll find more information about the best lash serums for volume, including the Trybello Eyelash Growth Serum, Borboleta Lash Serum, and Vegamour GRO Lash Serum.

3 Best Volumizing Eyelash Serums

1. Trybello Eyelash Growth Serum

Trybello Eyelash Growth Serum is vegan, cruelty-free, and prostaglandin-free.

Our Trybello 2-in-1 Eyelash Growth Serum combines a growth treatment and a mascara in a single product, meaning you're building volume while actively treating your lashes every time you wear it.

The growth serum end of the dual wand delivers a plant-based, prostaglandin-free formula of pentapeptide-17, panax ginseng extract, pumpkin seed extract, grape seed extract, hyaluronic acid, and biotin directly to the lash follicle. Meanwhile, the mascara end adds instant volume and lift while you wait for the growth serum to deliver its longer-term results.

The formula is free of oils, hormones, silicones, parabens, perfumes, PEGs, and prostaglandins, which means it avoids the side-effect concerns linked to prostaglandin-based serums, such as iris discoloration, periorbital fat loss, or eyelid darkening. It's dermatologically and ophthalmologically tested, 100% vegan, cruelty-free, gluten-free, and fragrance-free, making it safe for sensitive eyes, contact lens wearers, and lash extension users.

Results

The Trybello Eyelash Growth Serum’s growth timeline is one of the fastest on the market. During the first four weeks, lashes begin to feel nourished and conditioned as roots are strengthened and growth initiation begins.

By weeks four to six, visible improvements start to appear, with lashes looking longer, healthier, and fuller. Between weeks six and eight, volume and length become more noticeable as lashes enter the active growth phase. By weeks eight to twelve, lashes achieve their full potential, appearing thicker, stronger, and well-nourished.

This new and improved formula delivers reparative natural extracts and nourishing actives directly to the hair follicle to help eyelashes look visibly longer, thicker, and healthier in just 30 days with consistent daily use.

Reviews

Customer feedback consistently highlights two things: the clean formula and the dual wand convenience. Users who switched from prostaglandin-based serums frequently cite the Growth Serum as a safer alternative that still delivers visible results without the side effects they experienced with other brands.

Users report visible differences in lash volume in as little as 30 days of using Trybello 2-in-1 Eyelash Growth Serum.

Price

Our Trybello 2-in-1 Eyelash Growth Serum costs $49.95 and is currently available for $29.95, with free worldwide shipping for a 30-day supply. A 60-day supply costs $99.95, reduced to $39.96. We also offer free shipping worldwide and a 60-day hair growth guarantee.

2. Borboleta Lash Serum

Borboleta has spent over a decade in the lash care industry, originally serving professional lash artists before making their products available directly to consumers. Its Lash Serum is formulated with a blend of biotin, keratin, and peptides designed to condition and strengthen lashes. Additional ingredients include sodium hyaluronate for hydration, panthenol, soybean oil, and allantoin for soothing.

The serum is clinically tested, ophthalmologist-tested, and approved, cruelty-free, fragrance-free, and lash-extension-safe. Application is once nightly, one swipe along the upper lash line only, with a 90-second drying time before applying other products.

Results

Borboleta states that lashes will look fuller and thicker in as little as 4 weeks, with maximum results at 8 weeks with consistent nightly use. Its clinical data reports that 82% of users experienced stronger lashes after 42 days, 80% observed enhanced lash appearance after six weeks, and 80% reported fuller-looking lashes after regular use.

Reviews

Customer reviews are largely positive, with users frequently citing visible improvements in length and thickness and noting that the serum doesn't aggravate their eyes during regular use.

That said, some users have reported initial reactions, including crust around the eyes during the first few days of use, which typically subsided after the eyes adjusted to the product. A few also complain about the bottle's size, noting it is on the more expensive end.

Price

Borboleta Lash Serum is available in two sizes: a 1 mL sample size for $25 and a full-size 3 mL tube for $65. It's a single-function serum with no mascara component, so you'll need a separate product for daily wear.

3. Vegamour GRO Lash Serum

Vegamour's GRO Lash Serum is a plant-based, prostaglandin-free lash-enhancing serum that has built a significant following in the clean beauty market. The formula is powered by two key phytoactives, including red clover and mung bean, which are clinically shown to help address key causes of lash thinning. It also contains amino acid peptides that support follicle regeneration and glycerin for hydration.

The serum is formulated without silicones, parabens, phthalates, harmful sulfates, prostaglandins, or artificial fragrances, and it's 100% vegan, cruelty-free, and gluten-free. It is safe for use with lash extensions and contact lenses, and the precision tip applicator allows for targeted application along both the upper and lower lash lines.

Results

The brand claims visible results in as little as 30 days, with full results after two months of consistent twice-daily use. Its clinical study involved 30 participants over 60 days and demonstrated visibly fuller, longer-looking lashes. Some users report noticeable improvements in density and length within three to four weeks.

Reviews

On the positive side, many users describe dramatic results, such as thicker, longer lashes. The prostaglandin-free formula is a frequently cited reason for purchase, particularly among users who switched from other brands after experiencing side effects like eyelid darkening or concerns about periorbital fat loss.

On the other hand, a meaningful number of reviewers report inconsistent results. A few users also noted a stinging sensation when the serum made direct contact with the eye, though this appears to be an application issue rather than a formula reaction.

Price

GRO Lash Serum retails at approximately $68 for a 3 mL tube. A subscription option is available at a 16% discount through Vegamour's website. It is a single-function serum with no mascara component, and the twice-daily application for the first two months means you'll go through the product faster than with once-nightly serums.
