Ultimate Optimising Serum
Every repair function your skin needs. At once.
Composition No. 1 is the definitive expression of the AUTEUR philosophy — over 40 active ingredients working in concert overnight to rescue distressed skin, restore structural integrity, and reveal measurably healthier skin by morning.
Complimentary samples with every order.
Includes Cleansing Complex on orders over $250.
Most serums target one concern. Composition No. 1 targets the system.
Skin repair isn't a single mechanism — it's a stack of them. Peptides signal collagen production. Retinol accelerates turnover. Liquid Oxygen revives the cellular metabolism that makes the rest possible. Composition No. 1 layers all three plus 37 supporting actives into a single overnight serum, synchronized to the only repair window that matters.
The Formulation
Seven hero actives. Forty plus working in concert.
No single active carries the load. Each one amplifies the others — the architecture is what makes the result measurable.
SYN®-AKE Peptide
Neurotransmitter-inhibiting peptide that relaxes micro-muscular contractions and activates collagen production. Smooths and lifts from within while skin undergoes its natural overnight repair.
SYN®-HYCAN Peptide
Stimulates hyaluronic acid and collagen synthesis simultaneously. Restores dermal volume and deep structural hydration for measurably firmer, plumper skin by morning.
Gold Pro-Collagen Peptide
Amplifies the performance of the full peptide complex. Drives collagen synthesis, improves elasticity, and optimises delivery of hydration and luminosity-building actives.
Liquid Oxygen Complex
Perfluorocomplex penetrates the skin barrier to deliver oxygen to cells. Well-oxygenated cells repair and regenerate more efficiently — accelerating every dimension of overnight renewal.
Encapsulated Retinol
Encapsulation technology delivers retinol steadily through the night, accelerating cellular turnover and collagen stimulation without the irritation associated with direct retinol application.
Pentavitin® + Hyaluronic Acid
Pentavitin® binds moisture for lasting hydration that holds through the next day. Hyaluronic Acid delivers immediate surface plumping. Together they restore the moisture equilibrium that distressed skin has lost.
Niacinamide
Regulates sebum, refines pore appearance, and delivers antioxidant protection. Strengthens the barrier and improves skin tone overnight, contributing to the healthier overall appearance visible by morning.

The Ritual
Built for the overnight repair window.
The skin's most active period of cellular regeneration is the only time peptides, retinol, and oxygen carriers can do their full work. Composition No. 1 is engineered for that window — not a daytime serum.
Cleanse · PM only
Cleanse with your preferred AUTEUR cleanser. Pat dry. Composition No. 1 is an overnight treatment — apply only in the evening.
2 pumps · Face, neck, décolleté
Press 2 pumps across face, neck, and décolleté. Allow to absorb fully into the skin before following with your chosen AUTEUR cream.
Build up · Every other night → nightly
Start every other evening (or 3× weekly), alternating with a hydration-focused routine. Increase as skin adjusts to the concentrated formula.
Contains retinol · Use SPF daily · 8-week mark is when structural change becomes measurable.
Why One Bottle
The cost of not consolidating.
Most prestige serums target one mechanism. Composition No. 1 replaces the stack — peptides, retinol, oxygen, hydration, and barrier support in a single overnight application.
Frequently Asked
Questions, answered.
How quickly will I see results?
Most users notice smoother texture and improved radiance within 2 weeks. Clinical changes in firmness, elasticity, and line depth are measurable at the 8-week mark with consistent use. The architecture compounds over time — six months of nightly use produces structural change, not surface effect.
I've never used retinol. Can I start with Composition No. 1?
Yes — the encapsulated retinol delivery is significantly gentler than direct retinol. Begin every other evening (or 3× weekly) and layer it over a thin application of Hyaluron Activator if your skin is reactive. Increase frequency as tolerance builds. Use daily SPF.
Can I use this while pregnant or nursing?
No. Composition No. 1 contains retinol, which should be paused during pregnancy and nursing. Consult your physician. We recommend Hyaluron Activator and Definitive Eye Cream during this period as retinol-free alternatives.
Why is it $1,190?
Forty-plus high-performance actives at clinically validated concentrations, including SYN®-AKE, SYN®-HYCAN, Gold Pro-Collagen Peptide, and a Liquid Oxygen perfluorocomplex carrier. The formula consolidates what would otherwise require three to four separate prestige serums. The cost reflects the architecture, not packaging.
What if I want to try AUTEUR before committing?
Start with the Discovery Set ($40) — trial sizes of our most popular formulations including a Composition No. 1 sample. It's the way most of our customers begin. Discovery Set credit applies toward your first full-size purchase.
Can I combine it with other AUTEUR products?
Yes — Composition No. 1 is compatible with all AUTEUR formulations. Apply Composition No. 1 first in your evening routine, then follow with your chosen AUTEUR cream. For sensitive skin, layer over Hyaluron Activator Serum.
