Our Take

A science-backed lash serum that delivers real results without the controversy.

This serum trades the prostaglandin ingredients found in many lash products for peptides and amino acids—a gentler route to visible lash improvement.

$48 is mid-to-premium for a lash serum, but the 6 mL size and clinical backing justify the spend.

Who it is forBest for lash enthusiasts who want visible improvement without prostaglandin side-effect concerns, or anyone with sensitive eyes seeking a gentler growth option.

The Buying Guide

What to check before you buy

The Formula

Biotinoyl Tripeptide-1, Myristoyl Pentapeptide-4, proprietary amino acid blend

Peptides work as cellular messengers to support follicle health, while amino acids help build keratin for thickness. The prostaglandin-free approach means no risk of iris color shift or periorbital fat loss—a real differentiator for people with sensitive eyes or concerns about long-term side effects.

Size & Value

6 mL fill (vs. typical 3 mL competitors)

You're getting double the product, which stretches the cost-per-use and means fewer repurchases. At $48, the math feels fairer than half-sized bottles at similar price points.

Clean Credentials

Vegan, cruelty-free, free of parabens, sulfates, phthalates, silicones, artificial fragrances

If clean beauty matters to you, the ingredient list checks every box. Sustainable packaging rounds out the promise, so you're not compromising your values for results.
