BY TRYBELLO
Jun 08, 2026
Key Takeaways

- The Ordinary is the most affordable at $14.90 (365-day return on unopened product), RapidLash is $34.95 (returns vary by retailer), and Trybello is $39.95 with a 60-day growth guarantee.
- Results timelines run close: Trybello shows visible change in about 4 weeks, The Ordinary claims 4 weeks (some users report 8–12), and RapidLash estimates 1 to 2 months.
- Reviews favor Trybello for gentleness, while The Ordinary draws applicator complaints, and RapidLash draws some reports of irritation.
- Trybello lash serum stands out for its dual-wand design, which combines a peptide-driven growth serum and a volumizing mascara in one applicator, priced at $39.95 and formulated with a plant-based, prostaglandin-free formula.
The Ordinary vs RapidLash vs Trybello: Three Serums, One Clear Winner
The clear winner is the Trybello 2-in-1 Eyelash Growth Serum. It's the only one of the three that pairs a peptide-led growth formula with a built-in volumizing mascara, and it does so without the prostaglandin analog.
All three serums target lash growth differently. The Ordinary takes the budget route with a four-peptide complex at $14.90; RapidLash uses Isopropyl Cloprostenate alongside its HEXATEIN 1 Complex, with brand-disclosed side-effect warnings, at $34.95; and Trybello centers on Pentapeptide-17, Panax ginseng, and clean, plant-based actives at $39.95. They also differ in result timelines, money-back terms, and how easily each fits into a daily routine; the dual-wand format being Trybello's quiet advantage.
Below, we break down each serum on ingredients, results timelines, cost, and real user reviews.

Trybello 2-in-1 Eyelash Growth Serum
Trybello replaces two lash products with one daily-use applicator.
The Trybello 2-in-1 Eyelash Growth Serum is built around a clean, peptide-forward formula housed in a dual-wand applicator. One end carries a growth-supporting serum, and the other doubles as a volumizing mascara, so daily lash care and lash styling happen in the same step.
The serum is prostaglandin-free, making it suitable for daily use. Combined with the dual-wand design, it's a format that's easy to keep up with long enough for results to show.
What's Inside the Formula
One of the main ingredients in Trybello lash serum is Pentapeptide-17, a signaling peptide linked to stimulating keratin production in lash follicles. Alongside it, Panax Ginseng works at the follicle base to support circulation, and Pumpkin Seed Extract nourishes the lash shaft.
Grape Seed Extract acts as a natural antioxidant against environmental stress, Biotin strengthens the hair shaft, and Hyaluronic Acid keeps the delicate lash line hydrated. This combination addresses lash growth from multiple biological angles simultaneously: follicle stimulation, shaft strength, and moisture retention.
How Long Before You See Results
With consistent daily use, many Trybello users notice their lashes feeling healthier and more conditioned within the first four weeks. Lashes appear fuller and more defined, with more noticeable length and thickness often seen after 6 to 8 weeks of regular application. We recommend applying once or twice daily, with twice daily preferred during the first 2 months for maximum results.
Cost
The Trybello 2-in-1 Eyelash Growth Serum is priced at $39.95 (regularly $49.95) and includes free shipping on all orders. Every bottle is backed by our 60-day growth guarantee.
What Users Say About It
Trybello users consistently mention visible lash improvement within the first month of consistent use, as well as the formula's gentleness around the eye area. Reviewers with sensitive eyes are among the most vocal in their praise, often citing the clean, fragrance-free formula as a major reason for sticking with it.
Trybello users dealing with lash damage consistently report recovery and stronger natural growth.
The Ordinary Multi-Peptide Lash & Brow Serum
The Ordinary built its reputation on making clinical-grade skincare ingredients accessible without a luxury price tag, and its Multi-Peptide Lash & Brow Serum follows the same philosophy.
The serum is formulated to work on both lashes and brows, making it a versatile option for users looking to address both areas with a single product. The formula is also prostaglandin-free, relying instead on a peptide and botanical complex.
What's Inside the Formula
The Ordinary's formula is built around four peptide complexes: Myristoyl Pentapeptide-17, Biotinoyl Tripeptide-1, Oligopeptide-2, and Acetyl Tetrapeptide-3. It also contains
How Long Before You See Results
The Ordinary markets visible improvements in lash volume and fullness in as little as 4 weeks of consistent twice-daily use. Most user reviews align with this timeline, though some report needing closer to 8 to 12 weeks before noticing visible changes.
Cost
At $14.90, The Ordinary is a clear budget-friendly serum. For anyone experimenting with lash serums for the first time and not ready to invest more, this is a low-stakes entry point.
What Users Say About It
Some users report subtle but real improvements in lash density after four to six weeks of nightly use, while others see minimal change even after completing a full bottle. The most recurring criticism centers on the brush applicator, which several reviewers describe as stiff and difficult to apply cleanly along the lash line, with some noting it splays or separates over time. For the price, it's worth trying, but manage expectations accordingly.
Users often note that The Ordinary's formula is gentle and non-irritating, but visible results can be subtle.
RapidLash Eyelash Enhancing Serum
RapidLash has been a recognizable name in the lash serum category for years, and its longevity in the market speaks to a loyal user base. The brand markets it as a conditioning and enhancing serum, with a formula that includes a prostaglandin analog, putting it in a different ingredient category from the other two products in this comparison.
What's Inside the Formula
RapidLash's formula contains its proprietary HEXATEIN 1 Complex, a blend of six ingredients: Polypeptides, Biotin, Panthenol, Amino Acids, Soybean Oil, and Pumpkin Seed Extract. These ingredients work as conditioning and structural support agents, strengthening lash fibers and reducing brittleness. The serum also contains Sodium Hyaluronate, Glycerin, and several signaling peptides.
Importantly, RapidLash includes Isopropyl Cloprostenate, a synthetic prostaglandin analog, which may cause side effects such as eye redness, dry eyes, watering, sensitivity, darkening of the eyelid skin, iris discoloration, and orbital fat loss.
How Long Before You See Results
RapidLash estimates its results timeline at 1 to 2 months with consistent nightly use. Users tend to notice changes in lash conditioning and reduced shedding within the first few weeks, with more visible length and density gains over the full 6 to 8 week mark.
Cost
RapidLash retails for $34.95. The brand doesn't offer a money-back guarantee for growth, though most retailers may offer their own return policies.
What Users Say About It
RapidLash has a broad and established review base across retail platforms. Users consistently report visible lash improvement and reduced shedding within 4 to 8 weeks of consistent nightly use, particularly among users dealing with thinning from age or extension damage.
Reviewers note that RapidLash delivers visible lash growth, though the timeline differs for users.
