Built to the Ruski Standard
Panthenol, held to the Ruski Standard
Glass Lash is a clear conditioning mascara led by panthenol (provitamin B5), with supporting biotinoyl tripeptide-1 and hyaluronate. It coats for the look of sleek, glossy, separated lashes, a “glass” finish, while the humectant-conditioner story stays cosmetic. Panthenol’s hair-conditioning evidence is strong in general cosmetic science; lash-specific RCTs are limited. Wear alone for sheen or under/over colour. No prostaglandin analogues. Remove gently; layer with serum in your night routine if desired.

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 water base that carries the film-formers, humectants and peptide and lets the clear gel spread evenly along each lash.
Established cosmetic-science consensus; water is the standard solvent base for a water-based conditioning gel.
Glycerin (vegetable glycerine) · INCI: Glycerinhumectant
Draws and holds moisture along the lash so the gel conditions rather than dries lashes out through the day.
Established cosmetic-science consensus; glycerin is one of the best-characterised humectants in topical formulation.
Panthenol (provitamin B5) · INCI: Panthenolconditioning agent
The lead conditioning agent in the Panthenol Clear Shield Complex; binds water into the lash fibre to keep lashes supple and looking glossy and healthy.
Well established in hair-science literature as a humectant and conditioning agent that improves fibre moisture and pliability; direct peer-reviewed lash-specific data is limited.
VP/VA copolymer (film-forming polymer) · INCI: VP/VA Copolymerfilm-former
Forms a flexible clear film that grooms lashes into place and holds the shape without flaking or a wet look.
Established cosmetic-science consensus; VP/VA copolymers are standard hold and film agents in mascaras and styling products.
Acrylates copolymer (film-forming polymer) · INCI: Acrylates Copolymerfilm-former
Adds long-wearing hold and water resistance to the clear film so groomed lashes stay set through the day.
Established cosmetic-science consensus on acrylate film-formers for wear and hold in eye cosmetics.
Propanediol (plant-derived glycol) · INCI: Propanediolcarrier/solvent
A plant-derived solvent and secondary humectant that keeps the peptide and actives in solution, improves glide, and supports the preservative system.
Established cosmetic-science consensus; propanediol is a widely used solvent, humectant and preservative booster.
PVP (polyvinylpyrrolidone) · INCI: PVPfilm-former
A film-forming polymer that adds groom and hold and contributes to the glossy, glass-like finish on the lash.
Established cosmetic-science consensus; PVP is a classic hold and fixative polymer in mascara and hair-styling formats.
Carnauba wax (plant wax) · INCI: Copernicia Cerifera (Carnauba) Waxthickener
A hard plant wax that structures the gel and delivers the high-gloss, glass-like sheen while helping lashes hold their groomed shape.
Established cosmetic-science consensus; carnauba is a standard high-gloss structuring wax in mascara and a vegan alternative to beeswax.
Sodium hyaluronate (hyaluronic acid salt) · INCI: Sodium Hyaluronatehumectant
A lightweight humectant that holds moisture at the lash surface to keep lashes conditioned and looking healthy beneath the film.
Established cosmetic-science consensus on sodium hyaluronate as a high-capacity humectant; lash-specific peer-reviewed data is limited.
Biotinoyl Tripeptide-1 (biotin-linked peptide) · INCI: Biotinoyl Tripeptide-1active
The formula's studied peptide active, included to condition the lash and support the appearance of healthy, well-conditioned lashes over continued use.
Supported mainly by supplier and manufacturer cosmetic data (Biotinoyl Tripeptide-1 is the peptide in Sederma's Procapil complex); independent peer-reviewed evidence in lashes specifically is limited, and no growth or physiological claim is made.
Biotin (vitamin B7) · INCI: Biotinconditioning agent
A vitamin cofactor included as a conditioning ingredient to complement the peptide in the leave-on gel.
Evidence for a topical biotin benefit on lashes is limited; biotin's established role relates to dietary sufficiency rather than topical application, and no growth claim is made.
Tocopherol (vitamin E) · INCI: Tocopherolantioxidant
Protects the formula's oxidisable ingredients from oxidation, keeping the clear gel stable across its six-month opened life.
Established cosmetic-science consensus; tocopherol is a standard lipophilic antioxidant used for formula stability.
Hydroxyethylcellulose (plant-cellulose thickener) · INCI: Hydroxyethylcellulosethickener
A cellulose-derived thickener that sets the gel's texture so it combs on evenly without clumping or dripping.
Established cosmetic-science consensus; hydroxyethylcellulose is a common non-ionic rheology modifier in water-based gels.
Dehydroacetic acid (preservative) · INCI: Dehydroacetic Acidpreservative
Part of the preservative system that keeps the water-based gel free from microbial growth in an eye-area product.
Established cosmetic-science consensus; used within regulatory limits as a broad-spectrum cosmetic preservative.
Benzyl alcohol (preservative) · INCI: Benzyl Alcoholpreservative
A preservative that broadens antimicrobial protection, which matters for a product used close to the eye.
Established cosmetic-science consensus; a widely permitted preservative within EU and TGA use limits.
Phenoxyethanol (preservative) · INCI: Phenoxyethanolpreservative
The primary broad-spectrum preservative protecting the gel against bacteria and mould throughout use.
Established cosmetic-science consensus; phenoxyethanol is among the most-studied cosmetic preservatives and is used within regulatory limits.
Ethylhexylglycerin (preservative booster) · INCI: Ethylhexylglycerinpreservative
Boosts the phenoxyethanol system and softens the feel of the gel, allowing a lower total preservative load.
Established cosmetic-science consensus; commonly paired with phenoxyethanol as a preservative booster and conditioning agent.

Questions, answered
Can I use Glass Lash Clear Conditioning Mascara with lash extensions and lifts?
Yes. Glass Lash is a water-based, oil-free conditioning gel, so it grooms and sets lashes without the oils that can weaken extension adhesive or soften a fresh lift. Comb it through gently and let it set.
Is Glass Lash suitable for sensitive eyes?
It is designed with sensitive eyes in mind. The gel is fragrance-free, pigment-free and prostaglandin-free, with a broad-spectrum preservative system kept within eye-area limits. As with any eye product, patch test first and stop use if irritation occurs.
How do I use Glass Lash, as a primer, polish or grooming gel?
Glass Lash does three jobs from one clear gel. Comb it through clean lashes as a primer under mascara for smoother application, wear it alone for a glossy no-makeup polish, or use it to groom and hold lashes in place. It layers cleanly under the peptide mascaras in the range.
How do I remove Glass Lash, and how long does it wear?
Glass Lash removes easily. It is a water-based conditioning gel rather than a waterproof or tubing mascara, so warm water and your usual gentle cleanser lift it away without scrubbing. It wears as an all-day groom-and-hold, and you can reapply as needed.
What should I expect from Glass Lash, and when?
Expect immediately groomed, glossier-looking lashes with a clear, no-makeup finish, plus a gel that stays comfortable through the day. Any conditioning contribution from Panthenol, hyaluronic acid and the Biotinoyl Tripeptide-1 peptide is a leave-on benefit over continued use. The third-party panel for this formula (RL-GLC-001) is available on request, and we describe what each ingredient does rather than promising an outcome.
