Key Ingredients
What's inside

Ingredients that work
as hard as you do.

①

Pisum Sativum Peptide — Pea Peptide

The hero active. Plant-derived peptides that signal lash follicles to strengthen the hair structure from root to tip. Applied daily, they improve lash density and resilience over time — this is what makes Peptide Extension a serum, not just a mascara.

Conditions · Strengthens · Builds over time
②

Carnauba Wax + Sunflower Seed Wax + Shorea Robusta Resin

Three plant-origin waxes that create buildable, flexible hold — no plastic film-formers, no synthetic polymers. The result is a formula that adds volume and length without the brittle coat that breaks lashes over time. Rinses completely clean.

Volume · Length · Flexible hold
③

Castor Oil — Ricinus Communis (Organic)

Cold-pressed organic castor oil has been used for centuries as a lash conditioning treatment. Rich in ricinoleic acid, it nourishes and softens each lash strand, preventing brittleness and supporting natural lash growth cycles.

④

CI 77499 — Pure Iron Oxide Pigment

The only pigment in this formula — a pure mineral iron oxide that delivers intense black colour with zero synthetic dyes. The same mineral pigments used in ECOCERT-certified skincare formulas. No PFAS, no coal-tar dyes, no contamination risk.

Pure mineral · Zero synthetic dyes · PFAS-free
⑤

Leuconostoc / Radish Root Ferment Filtrate

A natural preservative derived from radish root fermentation. Replaces synthetic preservatives like parabens or phenoxyethanol. Keeps the formula stable and safe for the delicate eye area without irritation risk.

How To Apply
Application Ritual

The technique that changes everything.

Most people lose half the effect of any mascara through application mistakes. Here's how to get the full benefit of a conditioning formula.

1

Start at the root

Press the wand gently against the base of your lash line and hold for one second before sweeping upward in a slow zig-zag motion. The root is where volume and lift originate — this is where the peptides do their best work.

Never start mid-lash. That's why mascaras look coated, not lengthened.
2

Build in thin layers

Apply two to three thin coats with 20 to 30 seconds between each. Thin layers build naturally and stay flexible. One thick coat creates clumping and puts mechanical stress on lashes.

Wait for each coat to slightly set before the next — patience is the technique.
3

Never pump the wand

Pull the wand out slowly and twist it instead. Each pump pushes air into the tube, drying out the formula and introducing bacteria near your eye. This single habit extends the life of your mascara significantly.

⚠️ Mascara expiration: Replace 3 months after opening — not the date on the box. After 90 days, the natural preservative system weakens. If the texture or scent changes, it's already time to replace.

"After the PFAS post from Coyoskin I threw out every mascara I owned and waited for this one. It actually lengthens without clumping and after 3 weeks my lashes look noticeably stronger. The fact that I can read every ingredient on the list — that's everything to me."

Questions

Everything you need to know.

No synthetic fragrances. No synthetic dyes. No parabens. The preservative is a natural radish root ferment — chosen specifically for safety near the tear duct area. Every ingredient is ECOCERT COSMOS Natural approved, which means it passed one of the strictest safety screenings in cosmetics worldwide.
Zero. No ingredient in this formula ends in "-fluoro", "-fluoroalkyl" or "-perfluoro". The formula is built entirely from plant waxes, natural oils, a mineral pigment, and a pea peptide. ECOCERT COSMOS Natural certification prohibits synthetic compounds of this type entirely.
The pea peptide (Pisum Sativum) is a plant-derived active with documented activity in hair follicle support research. Combined with organic Castor Oil — one of the most researched natural lash conditioners — the formula is genuinely designed to improve lash health over time, not just coat them for one day. Results are visible after consistent daily use over 3 to 4 weeks.
Peptide Extension is a buildable formula — two to three coats deliver full length and volume. If you're used to synthetic film-former mascaras that maximize coverage in one coat at the cost of flexibility and lash health, the texture will feel different: lighter, more flexible, and genuinely conditioning. The payoff is healthier lashes over time.
