41 Compounds. Zero Fillers.
Every compound in an AUTEUR formulation is included at a concentration where clinical literature shows it begins to work. Nothing is here for label appeal. Nothing is here at trace levels. If it's in the formula, it's doing something.
Ingredient LibraryWhy Concentration Matters More Than Ingredients
Most skincare brands list impressive ingredients. Few disclose at what concentration. A serum that contains retinol at 0.01% and one that contains it at 0.5% both say "retinol" on the label. The difference in efficacy is not marginal. It is the difference between a marketing claim and a clinical result.
AUTEUR formulates every active at or above the concentration threshold where peer-reviewed research demonstrates measurable effect. This means fewer ingredients per formula (because effective concentrations take up formulation space) and more deliberate architecture (because actives at real concentrations interact with each other and with skin biology in ways that need to be managed). The result: 41 bio-active compounds across formulations, each earning its place through published data- not marketing convention.

What's not in an AUTEUR Formula
Synthetic fragrance. Parabens. Phthalates. Sulphates. Mineral oil. Silicone fillers. Drying alcohols. Artificial colourants.
Every ingredient excluded from AUTEUR formulations is removed with intention: either it interferes with the performance of active compounds, compromises barrier integrity, or offers no functional value beyond sensory appeal. We don’t exclude ingredients for marketing- we exclude them to preserve formulation integrity.
The distinction matters. "Free from" lists are often marketing theatre. Our exclusions are functional decisions made during formulation architecture.
The Technology Inside Each Formula
Core Peptide Technologies
Many AUTEUR formulas are built around advanced peptide systems designed to support collagen renewal, skin density, and structural firmness. These signaling peptides help reinforce the skin’s architecture and improve the appearance of fine lines and elasticity over time.
Regeneration and Renewal Actives
Selected bio-active ingredients support visible skin renewal and improved texture. These actives help stimulate cellular turnover, refine uneven tone, and promote a smoother, more resilient complexion.
Hydration and Barrier Support
Multi-layer hydration ingredients help reinforce the skin barrier and maintain optimal moisture levels. These components support long lasting hydration while improving skin comfort, balance, and overall skin health.
Sourcing and Standards
Every raw material supplier in the AUTEUR supply chain is evaluated for purity, stability, and traceability. We source from pharmaceutical-grade suppliers where possible, and every batch of incoming material is tested against our specifications before formulation begins.
All AUTEUR formulations undergo stability testing at multiple temperature and humidity conditions, compatibility evaluation to ensure active compounds maintain potency when combined, and safety assessments that meet EU cosmetic regulations (the most stringent global standard).
The difference between a clinical skincare brand and a brand that uses clinical language is what happens before the product reaches the packaging.
