Peptide Prep Lash Cleansing Foam
Clean lash line & serum prep
Hybrid formulation
Lash hygiene is the single biggest driver of extension retention and lash-line health, and the step most people skip. This pH-balanced foam clears makeup, oil and debris without stripping, and adds Biotinoyl Tripeptide-1 for peptide-powered conditioning, so natural lashes stay healthy, conditioned and prepped for serum.

Built to the Ruski Standard
Biotinoyl Tripeptide-1, held to the Ruski Standard
Prep is the first step of a peptide routine. Biotinoyl Tripeptide-1 is the named peptide active in this cleansing foam, paired with panthenol, hyaluronate and allantoin for a conditioned feel after rinse. It does not replace a leave-on serum; it supports a clean canvas and the appearance of cared-for fibres. Rinse-off contact time limits how much peptide remains, we state that honestly. No prostaglandins, no fragrance. Massage onto damp lashes, rinse, then follow with serum.

The formulation
Every ingredient earns its place. Here is each one: what it is, why it's in this formula, and what evidence supports it, including where that evidence is limited.
Water · INCI: Aqua (Water)carrier/solvent
The base solvent that dissolves the humectants, surfactants and peptide and lets the whole formula foam and rinse cleanly away from the lash line.
Water as the primary cosmetic solvent is established cosmetic-science consensus.
Vegetable glycerine · INCI: Glycerinhumectant
Draws and holds water to offset any tightness from cleansing, so lashes and the lash line feel conditioned rather than stripped after rinsing.
Glycerin's humectancy is one of the most firmly established findings in cosmetic science.
Coconut-derived mild surfactant · INCI: Cocamidopropyl Betainesurfactant
A gentle co-surfactant that builds soft foam and helps lift makeup and oil while lowering the overall irritation potential of the cleansing system.
Its use as a mildness-boosting secondary surfactant is established cosmetic-science consensus; note it is a recognised, if uncommon, contact allergen, which is why it sits at a low supporting level.
Sugar-derived mild surfactant · INCI: Decyl Glucosidesurfactant
A plant-sugar non-ionic surfactant chosen for eye-area tolerance; it cleanses without stripping the lash line.
Alkyl glucosides are well documented in cosmetic science as low-irritation cleansing agents.
Amino-acid-derived surfactant · INCI: Sodium Lauroyl Glutamatesurfactant
The primary cleansing surfactant, derived from glutamic acid, providing the main makeup-and-oil-lifting action at a skin-friendly, near-physiological pH.
Glutamate (amino-acid) surfactants are recognised in cosmetic science as mild, low-irritation cleansers well suited to the eye area.
Corn-derived glycol · INCI: Propanediolhumectant
Hydrates and acts as a solvent that helps disperse the peptide and botanical extract evenly through the water phase, while also supporting preservative efficacy.
Propanediol's combined humectant, solubilising and preservative-boosting roles are established cosmetic-science consensus.
Provitamin B5 · INCI: Panthenolconditioning agent
Conditions the lash and lash line and improves smoothness and surface feel after a rinse-off cleanse.
Panthenol's conditioning and humectant function is established cosmetic-science consensus; independent peer-reviewed evidence specific to eyelashes is limited.
Hyaluronic acid salt · INCI: Sodium Hyaluronatehumectant
Binds water at the surface so lashes feel hydrated and conditioned rather than tight once the cleanser is rinsed away.
Sodium hyaluronate's surface humectancy is well established in cosmetic science.
Rosemary leaf extract · INCI: Rosmarinus Officinalis (Rosemary) Leaf Extractantioxidant
A botanical extract included for its polyphenol antioxidants, adding a light conditioning note and helping stabilise the formula.
Rosemary polyphenols such as rosmarinic and carnosic acid have documented antioxidant activity; at extract level in a rinse-off cleanser the functional contribution is modest.
Allantoin (soothing agent) · INCI: Allantoinconditioning agent
A soothing skin-conditioning agent that helps keep the delicate lash line comfortable during daily cleansing.
Allantoin's soothing and skin-conditioning role is established cosmetic-science consensus.
Biotin-linked tripeptide · INCI: Biotinoyl Tripeptide-1active
The signature peptide that ties the cleanse into the peptide range, leaving a light conditioning deposit so lashes feel looked-after even in a rinse-off format.
Marketed via supplier data (as the peptide in Sederma's Procapil complex) for hair and scalp conditioning; independent peer-reviewed evidence in eyelashes is limited, and the short contact time of a rinse-off cleanser further limits deposition.
Chelating agent · INCI: Disodium EDTApreservative
Binds trace metal ions from water and hard-water rinsing so the surfactants foam consistently and the preservative system stays effective.
EDTA's chelating and preservative-supporting role is established cosmetic-science consensus.
Salt · INCI: Sodium Chloridethickener
Adjusts the viscosity of the surfactant blend so the foam has the right density and slip through the pump.
Salt as a viscosity modifier in anionic surfactant systems is established cosmetic-science consensus.
Citric acid · INCI: Citric AcidpH adjuster
Fine-tunes the formula to a mildly acidic, eye-area-friendly pH that keeps the surfactants gentle and the peptide stable.
Citric acid as a pH adjuster is established cosmetic-science consensus.
Benzoate preservative · INCI: Sodium Benzoatepreservative
Part of the preservative system guarding a water-rich formula against microbial growth, and most active at this cleanser's mildly acidic pH.
Sodium benzoate's preservative function is established cosmetic-science consensus and it is a widely permitted cosmetic preservative.
Sorbate preservative · INCI: Potassium Sorbatepreservative
Works alongside sodium benzoate to protect the water phase against yeast and mould.
Potassium sorbate's preservative role is established cosmetic-science consensus.
Phenoxyethanolpreservative
Broad-spectrum preservative that keeps the cleanser microbiologically safe across its in-use life.
Broad-spectrum preservative efficacy is established cosmetic-science consensus; it is permitted up to 1% in cosmetics under EU and TGA limits.
Ethylhexylglycerinpreservative
A preservative booster and mild conditioning agent that strengthens the phenoxyethanol system and improves skin feel.
Its role as a preservative potentiator and secondary conditioning agent is established cosmetic-science consensus.

Questions, answered
Can I use Peptide Prep Lash Cleansing Foam with lash extensions and lifts?
Yes. It is completely oil-free and uses gentle, non-stripping surfactants, so it is formulated without oils that can weaken extension adhesive or relax a lash lift. Oil is the main threat to extension retention, which is why this cleanser is formulated without it and lists Oils among what it leaves out.
Is the cleansing foam gentle enough for sensitive eyes?
Yes. The foam is pH-balanced to sit close to the skin's natural range and is built on mild amino-acid and plant-sugar surfactants, with no added fragrance, oils or sulfates. As with any eye-area product, rinse well and stop use if irritation occurs.
Where does the cleansing foam fit into a lash routine?
Use it first, as the cleansing step before your serum. Massage a small amount over damp lashes and the lash line, rinse, pat dry, then apply your peptide serum to a clean, oil-free lash line so it can sit against the lash without makeup or sebum in the way.
What does the Biotinoyl Tripeptide-1 actually do in a rinse-off cleanser?
It leaves a light conditioning deposit that helps lashes feel smooth and looked-after, and it connects the cleanse to the rest of the peptide range. To be honest about the format: contact time in a rinse-off cleanser is short, so this is a conditioning finish to a cleansing step rather than a treatment. The serums are where the peptide technology does its main work.
How often should I use it, and what should I expect?
Use it once daily, ideally in the evening to remove the day's makeup, oil and debris before serum. Expect a clean, comfortable, non-tight lash line and lashes that feel conditioned rather than stripped. The third-party test panel is on file and available on request. It is a hygiene and prep step, so the outcome is about a clean, well-kept lash line, not a change to the lashes themselves.
