Lash Serum by KeraFactor
Lashes by KeraFactor®
A lash serum built on biology, not lash-growth folklore.
Lashes by KeraFactor is formulated with nine biomimetic growth factors and skin proteins — the same science behind the brand's scalp line, adapted for the delicate lash area. At its core, PDRN (PolyDeoxyRiboNucleotide) enhances cellular metabolism and increases blood flow to revitalize dormant follicles, while sh-Oligopeptide-1 and sh-Oligopeptide-4 stimulate the follicle, improve circulation, and support a longer growth (anagen) phase — the combination behind fuller, thicker-looking, healthier lashes.
The formula also includes NMN and adenosine for cellular repair, along with antioxidants like acetyl cysteine and glutathione to protect against oxidative stress. It's completely free of prostaglandin analogs (PGAs) — meaning no risk of iris discoloration or skin darkening around the eye, unlike many lash-growth serums on the market. Drug-free, hormone-free, and formulated without sulfates, parabens, or fragrance.
Why it works: Rather than relying on prostaglandin analogs to force growth (with the side effects that come with them), this formula works with the follicle's own biology — improving circulation and extending the growth phase for lashes that are fortified from root to tip.
How to use it:
- Remove all makeup and contact lenses before applying.
- Apply once daily along the base of the upper lash line only.
- Avoid the lower lash line and direct eye contact.
- Use consistently — growth-factor serums build results over weeks, not days.
The worth//vitality promise
Lash serums have a reputation problem — half the market works by borrowing side effects from glaucoma medication. This one doesn't. It earns its place because it's doing the same thing our scalp lineup does: activating what's already there instead of forcing a shortcut. No color-shift risk, no guesswork — just consistent, biology-first care for one of the most sensitive areas on your face.
