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, synchronised to the only repair window that matters.
Engineered for the hours your skin repairs itself.
Four jobs, one night, in concert.
Over 40 actives don't work in a line — they work as a system across the overnight repair window. Select a function to see what it does and which actives carry it.
Ease the muscular pull that etches lines
Neurotransmitter-inhibiting peptides soften the micro-contractions that press expression lines into skin, so overnight repair happens on a calmer surface.
Tap or arrow-key each function to explore the system.
Every active earns its place.
No single active carries the load. Each one amplifies the others — the architecture is what makes the result measurable. Explore the seven hero actives by the benefit they deliver.
Seven signature actives shown. The full Composition No. 1 formula carries over 40.
The numbers behind the architecture.
ARAMO ASW 300 + Cutometer MPA580 + Visioface 1300D imaging · 8 weeks, twice daily.
Two pumps. The last step before sleep.
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 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 · The 8-week mark is when structural change becomes measurable.
Tonight, by morning, and the months after.
Honest about the arc. Some of it you feel by morning; the structural work builds with consistent use.
$1,190 is the sticker. This is what a night costs.
One bottle replaces a multi-step routine and lasts months. Move the sliders to see your real cost per night.
Roughly the price of one lunch — for an overnight step that stands in for a serum, a retinol, a hydrator, an antioxidant and a firming treatment at once.
Math assumes ~0.2ml per pump. A 50ml bottle = ~125 applications at this setting. Actual mileage varies with how much you use.
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.

Questions, answered.
How quickly will I see results?+
By morning, skin looks rested, calmer, and more luminous — the effect you feel immediately. Measurable structural change (firmness, elasticity, wrinkle depth) builds with consistent nightly use; the 8-week study is where those changes become clinically measurable.
I've never used retinol. Can I start with Composition No. 1?+
Yes, but build gradually. The retinol is encapsulated for steady, low-irritation release. Begin every other evening (or 3× weekly), alternate with a hydration-focused routine, and increase to nightly as your skin adjusts.
Can I use this while pregnant or nursing?+
No. Composition No. 1 is formulated with retinol and is not advised during pregnancy or nursing. Please consult your physician for guidance during this period.
Why is it $1,190?+
It replaces a multi-serum routine — peptide signaling, encapsulated retinol, Liquid Oxygen, hydration, and barrier support — in a single overnight bottle. A comparable single-active stack runs $1,400 or more across three to four products.
What if I want to try AUTEUR before committing?+
Begin with the Definitive Discovery Set ($40) — trial sizes of our most popular formulations — or the Composition No. 1 Exploration Set, the three-step ritual built around the serum.
Can I combine it with other AUTEUR products?+
Yes. Cleanse and tone first, apply Composition No. 1, then seal with your chosen AUTEUR cream. Keep mornings focused on hydration and daily SPF.
Skin's architecture is rebuilt overnight. This is the protocol that does it.
One bottle. Seven hero actives. Forty-plus in concert. Engineered for the only repair window that matters.
