Key Takeaways

• Trybello Eyelash Serum uses a peptide- and plant-based formula, showing visible results in about 4 weeks with a gentle, prostaglandin-free profile suited to sensitive eyes.
• Nanolash's original serum works through ethyl tafluprostamide, a prostaglandin analog, but carries risks, such as irritation and possible eyelid or iris darkening.
  
• Lashcode is a peptide-and-botanical serum with results in about 2 to 3 weeks, but its published ingredient list also includes ethyl tafluprostamide, the same prostaglandin analog used in Nanolash.
  
• Trybello conditions and revitalizes lash follicles without prostaglandins to reduce risk, while both Nanolash and Lashcode list a prostaglandin analog that alters the growth cycle to speed results.
• At Trybello, our 100% natural formula is vegan, cruelty-free, and backed by a 60-day money-back guarantee, so you can see how your own lashes respond risk-free.

Nanolash vs Lashcode vs Trybello: Why Label Matters More Than Marketing

Two serums can describe themselves in similar, plant-forward terms and still work quite differently once you read all the way down the label. A formula's headline ingredients don't always tell the whole story, which is why the complete label is worth a careful look before you buy.

Take Lashcode, which leads with peptides and botanicals. Its published ingredient list also includes ethyl tafluprostamide, the same prostaglandin analog found in Nanolash's original serum, so it shares more with that formula than its positioning might suggest.

Our Trybello Lash Serum keeps things straightforward. It's built on Pentapeptide-17 and plant extracts with no prostaglandins at all, so what you read on the label is what goes near your eyes, backed by a 60-day money-back guarantee.

Trybello Lash Serum: Ingredients, Results & Side Effects

At Trybello, we’ve built a strong reputation in the lash care space by focusing on clean, scientifically supported formulas that prioritize both results and safety.

At Trybello, we formulated a eyelash serum that leads with one clear promise: scientifically supported lash-loving ingredients made with 100% natural compounds. As a US-based beauty and hair wellness brand, we take a peptide-led, plant-based approach to fuller-looking lashes.

Rather than using prostaglandin analogs, our formula works by conditioning and revitalizing lash follicles to support lash growth. The formula is vegan, cruelty-free, and free of parabens, silicones, PEGs, and synthetic fragrance.

It's designed for daily use along the upper and lower lash lines and is positioned as a gentler option for people with sensitive eyes or those who wear contacts.

Ingredients

Our Trybello Lash Serum centers on Pentapeptide-17, a peptide that supports the keratin proteins lashes are built from. Around it sits a blend of Panax ginseng extract to revitalize the follicles and support circulation at the lash line; biotin (vitamin B7) and panthenol (vitamin B5) to condition and reduce breakage; hyaluronic acid for hydration; and pumpkin seed and grape seed extracts for antioxidant protection.

Results

Most users see visibly longer, fuller lashes with consistent daily use over roughly 4 weeks, with continued improvement the longer the routine is kept up. Because the formula strengthens and supports growth rather than forcing the growth cycle with hormone-like actives, results build gradually and depend on consistent daily use.

Potential Side Effects

Our serum is free from harmful substances and suitable for sensitive eyes and contact lens wearers. As with any lash product applied near the eye, the sensible cautions still apply: patch-test first, keep it on the lash line rather than in the eye, and stop use if irritation develops.

Nanolash Lash Serum

The Nanolash Eyelash Serum conditions lashes with simple daily applications. (image source: Nanolash).

Nanolash is a lash serum from the Nanobrow/Nanolash brand, applied once daily along the lash line with a thin precision brush. Its original and best-known formula is built around a prostaglandin analog, which drives its relatively fast, visible changes in lash length and darkness.

Nanolash now sells two different serums: the original Eyelash Serum with the prostaglandin analog, and a newer Peptide Eyelash Serum that is prostaglandin-free. The two work through different mechanisms, so which one you're buying matters.

Ingredients

The original Nanolash Eyelash Serum uses a short ingredient list centered on ethyl tafluprostamide. This prostaglandin analog extends the lashes' growth phase, alongside Euphrasia officinalis (eyebright) extract, propylene glycol, sodium chloride, alcohol, a preservative, citric acid, and triethanolamine.

The separate Peptide version instead uses peptides such as Myristoyl Pentapeptide-17 and Myristoyl Hexapeptide-16, botanical extracts, and no prostaglandins.

Results

Many users reportedly see changes in lash length, thickness, and darkness within about 2 to 4 weeks of daily use, then tapering to a few times a week for maintenance. As with any lash serum, results depend on consistent application and vary by individual, and the faster visible change is largely attributable to the prostaglandin analog in the original formula.

Side Effects

Because the original formula contains a prostaglandin analog, it falls into the ingredient class associated with possible eye-area side effects, such as irritation, redness, and, with prostaglandins more broadly, darkening of the eyelid skin or iris in some users. Ingredient databases also list the original serum as neither vegan nor cruelty-free and note that it contains alcohol, which can irritate sensitive eyes.

Lashcode Lash Serum

The Lashcode Eyelash Serum contains soy and wheat germ extracts (image source: Lashcode).

Lashcode is a peptide-and-botanical eyelash serum from the same family of European lash brands, applied once daily at bedtime with a precision applicator. Unlike prostaglandin-based products, it aims to support lash growth and condition through nutrients and a peptide complex rather than hormone-like actives.

It's marketed as a nature-inspired, peptide-led option, but its published INCI list includes ethyl tafluprostamide, so mechanically, it sits closer to the original Nanolash formula than its positioning suggests.

Ingredients

Lashcode's formula combines a peptide complex that supports keratin production with soy and wheat germ extracts to repair and condition lashes. It also contains arginine and baicalein (Baikal skullcap root extract), a flavonoid that acts as a mild protective and antioxidant layer. Note, however, that Lashcode's published ingredient list also includes ethyl tafluprostamide, a prostaglandin analog, listed near the end of the INCI.

Results

Lashcode advertises visible improvement in lash strength and fullness in roughly 2 to 3 weeks of daily use, with fuller results building over continued application, making consistency an important factor. Individual results also vary.

Potential Side Effects

Because Lashcode's ingredient list includes ethyl tafluprostamide, it does not avoid the side-effect class tied to prostaglandin analogs, which can include eyelid skin darkening and iris pigmentation changes.

It contains soy- and wheat-derived proteins, so anyone with soy or gluten sensitivities should check the label before use. The usual lash-serum precautions apply: patch-test first and keep application to the lash line.

Nanolash vs Lashcode vs Trybello: Comparison Table

Why Trybello is The Safer, Healthier Choice

All three serums can leave lashes looking longer and fuller, so the real decision comes down to how much risk you're willing to accept in exchange for speed. Nanolash's original formula and Lashcode may act fastest but carry the side-effect profile associated with prostaglandin analogs, while Trybello trades a little of that speed for a gentler daily routine.

For most people who want results without that trade-off, our Trybello Lash Serum is the standout choice. It is vegan, cruelty-free, and free of parabens, silicones, and added fragrance, and the same bottle works on your upper and lower lashes and your brows. Best of all, it's backed by our 60-day money-back growth guarantee, so you can put it to the test with nothing to lose. Try Trybello Lash Serum and see what consistent, clean lash care can do.
