THE SERUM

A daily shave is a
stress event.

Four to seven times a week a blade is drawn across your face. Uneven tone. Visible irritation. Skin that never quite recovers. The Serum was built around that fact.

I

Evens the look of post-shave tone

A stable vitamin C derivative, niacinamide and alpha-arbutin work together to help reduce the look of uneven tone and visible marks along the jaw, beard line and neck.

II

Supports the skin barrier

SiriusBarrier™ supports skin through the daily stress a blade puts it under, so skin looks calmer, sooner, after every shave.

III

Supports the look of firmness

SiriusDefence™, our peptide complex, supports the look of firmness in skin that takes daily punishment and is expected to show none of it.

THE FORMULA

Named actives.
Disclosed percentages.
No botanical filler.

A long ingredient list is not a formulation strategy. Actives at working concentrations are. Every active is named, dosed and disclosed.

SiriusDefence™

Our proprietary peptide complex, built for the look of firmness in skin under the daily mechanical stress of shaving.

SiriusBarrier™

Our proprietary barrier-support complex, built to support skin through daily environmental and shave stress.

The Serum has not yet run its own clinical programme. Its actives have. Every one carries decades of independent published research, at a working concentration.

Sodium Ascorbyl Phosphate

Independently studied for skin brightening and the appearance of uneven tone, and documented for its stability where L-ascorbic acid degrades.

Niacinamide

Among the most extensively researched actives in skincare, with a long body of published work on the look of tone, texture and the skin barrier.

Alpha-Arbutin

Independently studied for its effect on the appearance of dark marks and uneven pigmentation, the concern this formula was built around.

Matrixyl Synthe’6®

A peptide with published research behind it, used at the concentration the research describes, within SiriusDefence™.

THE pH RULE

Traditional vitamin C needs a pH of around 3 to work. On a freshly shaved jaw, that is a formula that stings.

The Serum uses sodium ascorbyl phosphate, the stable form, working at pH 6.5, close to skin’s own. It stays stable in the bottle, it does not oxidise orange, and it does not punish skin that is shaved most days.

THE FOUNDING 500

Not a waiting list.
A founding position.

The first five hundred customers are recorded permanently as founders. Your number is yours, never reissued, and its terms are never offered again.

I

A numbered place

Your founding number, one of five hundred, is assigned the moment you reserve The Serum. Your card is simply held against your place; nothing is charged until the fixed launch date.

II

Founding terms, held privately

Every founding place carries terms on The Serum confirmed privately by email. They are not published here, and they will not be offered publicly at any point.

III

First access to everything that follows

Every release after The Serum reaches the Founding 500 first, before public availability, at founding terms. The range is built. It arrives in sequence.

IV

The object, revealed to you first

Matte black glass. A single metal. A number on the base. The finished object is shown to founding places before anyone else, and the first five hundred units carry their founding numbers.

THE GIFT

The gift he’d never
buy himself first.

He researches everything and treats himself to almost nothing. A numbered founding place held in his name is the gift he would never think to ask for and will never forget.

Register with your email, reserve the place in his name. His number is assigned at reservation, nothing is charged until launch day, and it arrives by email ready to give.

THE STANDARD

What we hold ourselves to
before you pay a pound.

I

Sixty days. Money back.

Use The Serum for sixty days from delivery. If it has not earned its place on your shelf, we return your money. No forms to argue with, no partial refunds.

II

Independently safety assessed

Every product is assessed by an independent safety assessor and registered under UK cosmetics regulation before a single unit is sold.

III

Made in London, batch by batch

Small numbered batches, each recorded and retained. Every bottle traces to its batch, and every batch keeps a reference sample.

IV

Nothing undisclosed

The full ingredient list is published at launch. Named actives at stated concentrations, no fragrance, and nothing there to lengthen the list.

Founded in London by Roger.
