Peptides and the Proteome
Skin is built from protein. We formulate for the whole network, not one peptide.
What are peptides?
We use the word peptide a lot. This is what we mean by it.
Peptides are short chains of amino acids; the same building blocks your skin uses to make proteins. Think of them as tiny biological messengers. Different peptides can carry different instructions, helping influence how skin behaves, responds and maintains itself.
And this is where it gets interesting. “Peptide” isn’t really one ingredient. It’s an entire field of science. There are thousands of possible peptide sequences, and changing the order, structure or size can change what a peptide does. So simply putting peptides on an ingredient list tells you surprisingly little. The clever bit is knowing which peptide, why it’s there, and what you want it to do. That precision is what makes peptide science so interesting to us and why we’re rather particular about the ones we use.
Why proteins come first
Skin is about more than collagen. Much more.
Skin is built from protein. Collagen gives it structure, elastin gives it spring, and keratin gives it resilience. Enzymes keep the whole system working as it should. Together these proteins form a living network, and the health of that network is what you see in the mirror as firmness, smoothness and light.
Our research began with that network. Because we don't look at one protein. And we don't work with one singular peptide. Our biology is more complex, and so is the environment we live in.
Working with proteomic scientists, we measured how proteins in skin samples respond to environmental stress in the laboratory, and how that damage accumulates over time. The findings shaped a simple conviction: if skin is made of protein, skincare should directly support the quality and health span of those proteins.
Peptides are that language. They are fragments of proteins. Mini proteins, in effect.
Not one peptide. A discipline.
We’ve never believed one hero peptide can do everything. Skin is far too complex for that.
We work across peptide technologies, selecting from the most advanced peptide science available. Sequences engineered through modern biotechnology for exceptional purity and precision. Each is chosen for a specific role, then formulated to work alongside the others and living within the 'chassis' of the formula that supports their delivery. Our Peptide Longevity Serum alone carries three distinct peptide technologies, each addressing a different dimension of how skin ages.
We call this multi-disciplinary peptide formulation: several precise tools, deliberately chosen, designed to work as one.
The proteome, measured.
The proteome is the complete set of proteins in your skin. Every structural fibre, every enzyme, every messenger, all working at once. It is where our research begins, because it’s where skin health lives.
In the lab we measure protein carbonylation, a marker of oxidative damage to proteins, in human skin samples exposed to environmental stress. It lets us see, at the level of the protein network itself, how skin responds to its environment and our formulas.
This evidence informs every peptide we select.
The result is skincare designed the way skin is designed: as a network. No single hero. No isolated fix. Peptides are our language, and the proteome is the story they belong to.
The science
What is the proteome, and why should I care?
Your skin is built from proteins. Collagen, elastin and keratin are the ones you have heard of. Together they are the proteome. When they are intact, skin holds its structure, its bounce and its barrier. When they are damaged, it does not. Almost everything you dislike about ageing skin is, underneath, a protein problem.
What is protein carbonylation?
It is what oxidative stress does to a protein. Think of rust on metal. Pollution, sunlight and daily life generate oxidation in the skin, and carbonylation is the mark it leaves. A carbonylated protein cannot do its job and cannot be repaired. It has to be replaced. We chose carbonylation because it can be measured, which means we can be checked.
Is this anti-ageing?
No. We do not think ageing is something to fight. Longevity is a different idea: extending the healthy working life of the proteins in your skin. Skin that is defended and rebuilt stays functional for longer. That is the whole aim.
How is this different from other longevity brands?
Most longevity skincare targets senescent cells, the "zombie" cells that stop dividing and cause trouble. That is real and important science. We work one step earlier. Protein damage is a driver of senescence, so we measure and address it before the cell reaches that state. Both approaches are legitimate. Ours is upstream, and it can be measured directly in the tissue.
Testing and evidence
How are your products tested?
Two ways. Every product is safety-assessed before sale, as the law requires, and every ingredient is chosen on published evidence. Beyond that, our serum and day cream were tested as finished products by OxiProteomics, an independent laboratory in Paris that specialises in measuring protein damage. The testing used living human skin explants under UV-A and pollution challenge, with the products applied before or after the stress. Data on file. The findings were presented at the European Society for Dermatological Research annual meeting in September 2026.
Were these clinical trials on real people?
No. The tests were run on living human skin in a laboratory, not on volunteers over months. Explant testing is a rigorous way to measure what happens inside the tissue, but it is not a consumer trial, and we will not tell you it is. Where we have results from people using the products, we will publish them.
Have all five products been tested this way?
No. The Peptide Longevity Serum and the Tripeptide Antioxidant Day Cream have finished-product results. The Balm-to-Milk Cleanser, the Bioretinol Overnight Rich Cream and the Sculpting Eye Serum are built on the same formulation standards, but they have not yet been through the same testing. We are saying so because you would want to know.
