Key Takeaways

• The three serums differ by one ingredient: Nanolash uses the prostaglandin analog ethyl tafluprostamide, while Scorolash and our Trybello serum are prostaglandin-free peptide formulas.
• Our Trybello serum pairs Pentapeptide-17 with ginseng, biotin, and pumpkin and grape seed extracts, while Scorolash uses two peptides plus ginseng, and Nanolash relies mainly on its prostaglandin active.
  
• Nanolash's prostaglandin carries that class's risks, like irritation and possible eyelid or iris darkening, while Scorolash and Trybello stay gentle enough for sensitive eyes.
  
• All three advertise visible results in roughly two to four weeks, but the prostaglandin-free formulas build results by revitalizing the lash follicles rather than forcing the growth cycle.
• Our Trybello Eyelash Growth Serum pairs its peptide serum with a volumizing mascara in one tube, stays vegan, and comes with a 60-day money-back guarantee.

Why the Ingredient List Decides How a Lash Serum Feels

Most shoppers compare lash serums on price or promised results, but the label tells you far more about what you're actually putting near your eyes. One active ingredient often decides how quickly a serum works, how comfortable it feels, and what side effects you risk over months of daily use.

Nanolash, Scorolash, and Trybello are all sold as eyelash growth serums, but they take very different approaches. Scorolash and our Trybello Eyelash Growth Serum don’t contain prostaglandin; instead, Trybello lash serum builds on peptides like Pentapeptide-17 plus botanical nutrients such as ginseng and pumpkin seed to strengthen the lashes you have.

Nanolash's classic serum leans on a hormone-like prostaglandin, ethyl tafluprostamide, to push faster length, but they carry documented risks such as irritation and darkening of the eyelid skin or iris, especially near sensitive eyes. The peptide route that Trybello takes rewards steady daily use, while staying gentle on sensitive eyes.

Trybello EyeLash Growth Serum

We formulated our Trybello Eyelash Growth Serum for anyone who wants visibly fuller lashes without relying on hormone-style ingredients. It's a leave-on treatment you sweep along the lash line, and in our 2-in-1 version it shares a tube with a volumizing mascara, so one purchase both treats and defines your lashes. Every ingredient is vegan and cruelty-free.

Rather than pushing the growth cycle the way prostaglandin serums do, our formula works by feeding and reinforcing the lashes you already have, using a peptide alongside a set of plant-based nutrients.

The Trybello Eyelash Serum is gluten-free, fragrance-free, and free from harmful chemicals.

Ingredients

The centerpiece is Pentapeptide-17, which supports the production of keratin, the protein that gives lashes their structure and strength. Around it, we've layered Panax ginseng root extract to encourage healthy follicle activity, biotin (B7) and panthenol (B5) to soften and guard against breakage, hyaluronic acid to lock in moisture, and antioxidant-rich pumpkin seed and grape seed extracts to protect against daily wear. What you won't find anywhere on the label is prostaglandins, hormones, oils, silicones, parabens, or synthetic fragrance.

Results

With once- or twice-daily use, most people begin to notice denser, longer-looking lashes across roughly four weeks, and the effect continues to build the longer the routine holds. Because we nourish and aid growth instead of chemically speeding up the growth phase, the improvement arrives steadily rather than overnight, which is why staying consistent matters far more than how much you apply.

Becky I., a Trybello customer, reports seeing longer and fuller lashes within 4 to 6 weeks of using the product.

Potential Side Effects

Leaving prostaglandins out means our serum sidesteps the issues that ingredient class is known for. We've made it gentle enough for sensitive eyes and contact lens wearers, and it's dermatologist-tested.

The usual eye-area precautions still apply: run a patch test before your first full application, keep the serum on the lash line rather than in the eye, and stop if you notice any redness or irritation.

Nanolash Eyelash Serum

Nanolash is a widely marketed European lash brand whose classic serum is applied once a day along the upper lash line with a precision brush. Unlike peptide-only formulas, it works through a prostaglandin analog, which is what powers the faster, more dramatic lengthening the brand advertises. The company also sells a separate prostaglandin-free peptide serum; you must confirm which formula a given listing refers to before buying.

Ingredients

Nanolash's ingredient list states that the classic serum contains water, ethyl tafluprostamide, Euphrasia officinalis (eyebright) extract, propylene glycol, sodium chloride, alcohol, phenoxyethanol, citric acid, and triethanolamine.

The active driver is ethyl tafluprostamide, a synthetic prostaglandin analog that extends the lashes' active growth phase. The rest of the list is largely solvents, a preservative, and pH adjusters, with eyebright extract as the main botanical.

Results

Nanolash states that users can see first results after about two weeks of daily use, with lashes up to 50% longer after 30 days, then a maintenance routine of two to three applications per week once the desired length is reached. Independent feedback is more varied: some long-term users report clearly longer, darker lashes, while others see little change even after finishing a full tube.

Potential Side Effects

Because the formula is prostaglandin-based, it belongs to the ingredient class linked to possible eye-area effects such as irritation, redness, and darkening of the eyelid skin or the iris, most often in people with mixed-color irises such as hazel or green-brown.

Some user reviews specifically report itching, redness, or swelling. Nanolash also lists clear contraindications on its own site, advising against use during pregnancy or breastfeeding and by anyone underage, and the formula contains alcohol, which can add to sensitivity for some users. A patch test before first use is a sensible precaution.

Scorolash Eyelash Serum

Scorolash is a US-based lash brand that offers a peptide-driven, prostaglandin-free growth serum applied once or twice daily along the lash line. Like Trybello, it works by supporting the lashes' natural renewal cycle rather than using hormone-like actives, positioning itself as a gentler option that's safe to use with mascara and lash extensions.

Ingredients

Scorolash's formula comprises two peptides, Myristoyl Pentapeptide-17 and Oligopeptide-10, supported by hyaluronate for hydration. It also contains Panax ginseng and Swertia japonica extracts to encourage follicle activity, and panthenol, pumpkin seed extract, saw palmetto, sweet flag root, and vitamin E. It contains no prostaglandins or hormones, and the brand lists the product as vegan, paraben-free, and gluten-free.

Results

Scorolash advertises visible results in as little as 2 weeks, with the brand recommending twice-daily use for the first month before easing off. Its own on-site figures cite high self-reported satisfaction with lash length and volume, and reviews on the page frequently describe fuller lashes over several weeks, particularly among users regrowing lashes after extensions.

Potential Side Effects

The brand describes the formula as gentle, though it advises a patch test for anyone sensitive or allergic to its ingredients, and a few reviewers mention minor initial sensitivity. The standard precautions apply: apply only to the lash line rather than the eyelid or eye, and stop use if irritation develops.
