It's time to look beneath the surface.
“Our science looks at how our biology behaves beneath the surface - The Proteome - for healthy proteins within our own biology.”
Susie Willis, Founder & CEO
The Biology of Beauty
What is The Proteome?
We're obsessed with the proteome, the protein structure inside your skin - the key to its longevity, health and resilience. Our research starts there, not at the surface, so skin keeps looking strong and healthy for longer.
Biologically Measured, Not Just Claimed
If we can't measure it, we won't say it. The Peptide Longevity Serum and the Tripeptide Antioxidant Day Cream have been through independent laboratory testing on human skin samples, rather than asking people what they noticed. We publish this protocol score.
The Latest in Biotechnology
Precision matters and we’re particular about it. We look to biotech for lab-engineered peptides and mini-proteins - ingredients made to a consistent specification in a controlled process, so we know exactly what is in a formula, and how much.
The Protocol Score
If we can't measure it, we won't say it.
12 of 12
Two studies, twelve protein-damage readings. Every one lower in treated samples.
CARBONYLATION · ALL AT P≤0.0 1
2.6×
UV light and pollution left skin samples with more than twice the damage to their proteins.
THE PROBLEM WE SET OUT TO MEASURE
TWO PROTOCOLS
One formula tested before exposure, one after. Defence and recovery, measured separately.
DAY CREAM · SERUM
CITY AIR + UVA
Certified urban pollution, then UV light, on ex vivo human skin.
THE EXPOSURE MODEL
Measured, not asked
A biological result, read from real human skin in the laboratory. Not a consumer panel reporting how their skin felt.
READ AT THE PROTEIN LEVEL
ESDR – HEIDELBERG 2026
Both studies accepted for presentation at Europe's leading meeting of skin scientists. Reviewed by dermatological researchers and displayed.
ACCEPTED FOR PRESENTATION · ESDR · HEIDELBERG 2026
Findings from two ex vivo studies on human skin explants, conducted by an independent laboratory: the Peptide Longevity Serum, applied after exposure, and the Tripeptide Antioxidant Day Cream, applied before exposure. Samples challenged with certified urban dust (PM10, 0.375 Qg/cm²) and UV-A (6 J/cm²); protein carbonylation and collagen I quantified against unstressed and stressed controls, donors, replicates per condition. One-way ANOVA with Dunnett's post-hoc test, α = 0.05. Accepted for presentation at the ESDR 55th Annual Meeting, September 2026.
Figures describe laboratory measurements on skin samples, not results in use. Other products in the system are supported by formulation architecture and attributed ingredient science.

Your questions, answered
We would rather you asked. Everything
below is the answer we would give you across a table.
Getting started
Do I need all five?
No. We built a system, not a rule. Most people should start with one. If your concern is daily exposure to the city, start with the day cream. If you want to rebuild, start with the serum. Add what you need, when you need it.
Is it for men?
It is for skin. Skin does not have a gender. The proteins in a man's dermis are damaged by the same things and rebuilt by the same signals.
Who is this not for?
Anyone expecting a change overnight. Anyone looking for a treatment for a medical skin condition, which these are not. And anyone who wants to be told what to buy rather than shown why. If that is you, there are simpler brands, and we mean that kindly.
How long before I see a difference?
Repair happens in stages. In the first days the skin calms and feels more comfortable. Over the following weeks texture and tone begin to even out. From about six weeks the deeper structural changes show at the surface. If you see nothing at twelve weeks, tell us.
Your routine
In what order do I apply them?
Cleanser, then serum, then eye serum, then day cream or night cream, then SPF in the morning. Thinnest to thickest.
How much should I use?
Less than you think. Two pumps of serum. A pea-sized amount of day cream. The peptides work at low doses, and more does not mean faster.
Do they sit well under make-up?
The serum absorbs fully. The day cream leaves a soft finish rather than a slip, so make-up goes on cleanly. Give each layer a minute. If you see pilling, you are using too much.
Can I use the day cream at night, or the night cream in the day?
You can, but you lose the point. The day cream is built to help defend skin against the day. The night cream is built to rebuild while you sleep. They do different jobs.
Will they stain my clothes, pillowcase or skin?
No. The colour absorbs with the product and does not transfer. Give it a minute before you dress or lie down, as you would with anything pigmented.
Care, storage and travel
How long does it last once opened?
Unopened, our products last for 34 months. Once opened, use within 12 months. Keep the lids on and keep them out of direct sunlight. Peptides do not improve with age.
Do I need to keep it in the fridge?
No. A cool, dark shelf is enough. The fridge does no harm if you like the feel of it.
Can I take it on a flight?
Yes. We have also created a collection of minis, for flights, the gym or simply on-the-go moments.
