Key Takeaways

• Trybello Eyelash Growth Serum is a plant-based, prostaglandin-free 2-in-1 serum and mascara dual wand built by our US-based team, with a 5 mL tube that delivers visible lash growth in about 4 weeks and is backed by a 60-Day Growth Guarantee.
• Babe Lash Essential Serum uses isopropyl cloprostenate to drive faster visible growth in 4 to 12 weeks, but carries possible side effects like eye irritation and lash line darkening, while Cosnori Long Active Eyelash Serum takes a K-beauty route with a prostaglandin-free peptide blend and a patented dual ball-point applicator at the lowest entry price.
  
• Cost varies widely across the three serums, with Cosnori at around $22 for 9 g, Babe Lash starting at $29 for 1 mL, and Trybello Eyelash Growth Serum at $39.95 for 5 mL, which makes volume and formulation depth more useful than sticker price when comparing value.
• The main pros across all three include visible lash improvements with consistent use, while the cons range from prostaglandin side effects with Babe Lash, to inconsistent results with Cosnori, to a slightly longer results timeline with Trybello.
• Trybello Eyelash Growth Serum is the safer daily pick for sensitive eyes, contact lens wearers, and long-term users, with a plant-based, prostaglandin-free formula made by our US-based team and backed by a 60-Day Growth Guarantee.

What Is The Difference Between Babe Lash, Cosnori & Trybello Lash Serums?

For long-term, daily-use lash care without the side effect risks tied to prostaglandins, our team at Trybello built the gentler option among the three serums in this comparison.

Babe Lash drives faster visible growth through a synthetic prostaglandin, Cosnori opens at the lowest entry price with a Korean peptide blend, and Trybello Eyelash Growth Serum, formulated by our US-based team, brings together plant-based actives in a 2-in-1 serum and mascara wand.

The right choice comes down to the priorities a buyer brings to the lash line. Speed, cost, and side effect tolerance shift the answer for sensitive eyes, contact lens wearers, and anyone planning a long-term routine.

This breakdown walks through cost, pros, and cons across all three serums, so the trade-offs are clear before any tube hits the cart.

Trybello 2-in-1 Eyelash Growth Serum Overview

Trybello 2-in-1 Eyelash Growth Serum + Mascara Dual Wand pairs a plant-based growth serum with a volumizing mascara.

Trybello Eyelash Growth Serum stands out in this comparison as the only product that doubles as both a lash serum and a mascara, eliminating one step from the morning routine without sacrificing lash care. We built the formula on a fully plant-based, prostaglandin-free foundation. Customers who use it daily start seeing visible results within 4 weeks.

Key Ingredients

Trybello contains Pentapeptide-17, a peptide that signals lash follicles to produce more keratin, the protein lashes are made of. Surrounding it is a botanical lineup chosen for follicle support:

Panax ginseng to revitalize follicles at the lash root, pumpkin seed extract to support and strengthen each lash, and grape seed extract to help defend the lash line from environmental stress.

Hyaluronic acid handles hydration, while biotin works behind the scenes to make each lash strand more resilient against breakage. Together, these actives stack peptide signaling with botanical nourishment and structural conditioning in a single tube.

Price

Trybello Eyelash Serum is currently $39.95 for a 5 mL tube, down from $49.95, and ships free across the US. Every purchase comes with our 60-Day Growth Guarantee, so the only commitment is the time to actually use it.

Pros

• Visible results reported within 4 weeks of consistent daily use
• Prostaglandin-free with no associated risk of iris darkening or eyelid pigmentation changes
• 2-in-1 dual wand combines a growth serum and mascara in one product
• Generous 5 mL tube delivering a full 30-day supply of peptide and botanical actives
• Vegan, cruelty-free, and 100% plant-based ingredient profile
• Free from oils, hormones, silicones, parabens, perfumes, and PEGs
• Backed by a 60-Day Growth Guarantee
• Safe for contact lens wearers and lash extension users
• Works on upper lashes, lower lashes, and eyebrows for a full eye-area routine

Cons

• Results may take longer to appear compared to prostaglandin-based options
• Primarily sold through the Trybello website and Amazon, so brick-and-mortar availability is limited

Babe Lash Essential Serum Overview

Babe Lash promises visible lash changes with consistent application over a 12-week use.

Babe Lash Essential Serum is from the popular Babe Original brand. It’s particularly known among lash retailers and beauty professionals. The serum is applied once nightly along the upper lash line, with the brand noting the 4-week mark for initial changes and the 12-week window for full effect.

Ingredients

Isopropyl cloprostenate carries most of the work in Babe Lash Essential Serum. The synthetic compound interacts with the lash cycle to prolong the follicles' growth window.

The supporting ingredients are biotin for keratin output, sodium hyaluronate for moisture retention, and panthenol to reduce brittleness. The serum also contains amino acids, vitamin E, and Panax ginseng root extract for general lash conditioning.

Price

Babe Lash Essential Serum comes in different sizes, including a 1 mL Mini at $29 (a 6-week supply) and a 2 mL at $49 (a 3-month supply).

Pros

• Visible changes reported within 4 weeks of nightly use
• Multiple size options to fit different commitment levels
• Available through professional beauty retailers
• Vegan, oil-free, and safe to use alongside lash extensions

Cons

• Contains isopropyl cloprostenate, a prostaglandin analog, with possible side effects in some users
• Possible side effects associated with prostaglandin analog formulas include eye irritation, redness, lash shedding, and skin darkening at the lash line
• Lashes immediately return to baseline after stopping

Cosnori Long Active Eyelash Serum Overview

Cosnori Long Active Eyelash Serum uses a peptide-based formula and a patented dual ball-point applicator for precise lash care.

Cosnori is a South Korean K-beauty brand, and its Long Active Eyelash Serum is one of the peptide-based options for lash growth. The formula is prostaglandin-free and uses a patented dual-ballpoint tip applicator for precise application along the lash line and roots.

Key Ingredients

Cosnori's serum hinges on its patented peptide blend, with Myristoyl Pentapeptide-17 leading the formula and copper tripeptide-1 supporting follicle conditioning.

Hyaluronic acid keeps the lash line moisturized, and centella asiatica (cica) extract, a K-beauty staple, lends soothing properties for the eye area. Panthenol and vitamin E round out the formula with conditioning and antioxidant support, all delivered in a pH-balanced base designed to match the natural pH of human tears.

Price

Cosnori Long Active Eyelash Serum typically retails around $22 for 9 g (0.3 fl oz) through K-beauty retailers, online marketplaces, and Costco listings.

Pros

• Prostaglandin-free formula with a vegan, oil-free composition
• Patented dual ball-point tip applicator for precision along the lash line and root
• pH-balanced to match human tears for a gentler experience
• Affordable entry point in the K-beauty lash category

Cons

• Twice-daily application means faster product use compared to once-daily formulas
• The results timeline can vary widely between users
• Results timelines reported by users can differ significantly between buyers
• Limited brick-and-mortar availability in markets outside South Korea

Babe Lash vs Cosnori vs Trybello Lash Serums: Comparison Table

What Makes Trybello Eyelash Growth Serum the Top Choice?

Trybello pairs a peptide-powered serum and a smudge-proof mascara in one tube.

Babe Lash delivers fast results, but the prostaglandin analog ingredient is associated with possible side effects in some users. Cosnori is a budget-friendly option with a clean formula, but it lacks the ingredient depth and the result-backing guarantee that make a serum worth committing to daily.

Trybello Eyelash Growth Serum fills the gap that both competitors miss. We deliver a multi-mechanism, plant-based formula that targets lash growth, strength, and volume at the same time, wrapped into a 2-in-1 mascara format for real daily convenience, and backed by a 60-Day Growth Guarantee. At $39.95, every tube combines a full 30-day supply of our peptide-powered serum with a built-in volumizing mascara, giving daily users a complete lash system in one tube.
