Designed for skin longevity, this serum combines advanced peptide technologies, lasting hydration and antioxidant care to help skin look firmer, smoother and more radiant. Skin longevity is about helping skin keep its resilient, healthy look in the face of time and everyday environmental stress. Our formulation work starts with the proteome, the network of proteins that gives skin its structure. At the heart of this formula is a proprietary peptide complex developed from that research, formulated to help skin look firmer, smoother and more resilient over time. 

Formulated with precision 
Developed from research into oxidative protein damage, the formula is designed to help skin look firmer, smoother and more radiant, and to keep looking that way. 

Results that last 
Skincare rewards consistency. Used daily, this serum helps improve the appearance of firmness, radiance and resilience, for skin that looks bouncy, healthy and refreshed. 

Measured in the laboratory 
When skin meets UV and pollution, free radicals form. These can damage the proteins that give skin its firmness and resilience. In independent laboratory testing on human skin samples exposed to UV-A and pollution, samples treated with this formula showed lower levels of oxidatively damaged protein, and higher Collagen I levels, than untreated samples. 

Measurements on excised human skin under laboratory challenge conditions - not a study of people using the product, and not a measure of how skin looks. Data on file. 

Formulated from the proteome Our research starts with the proteome — the network of proteins that gives skin its structure. This formula was developed from that research, combining peptide, mini-protein and botanical technologies to help skin look firmer, smoother and more resilient over time.

Firmer, more resilient-looking skin Peptide and protein technologies work together to help improve the appearance of firmness and elasticity, leaving skin looking smoother, firmer and more supple.

Antioxidant care for everyday stress City air, daylight and daily life all take a visible toll. Antioxidant technologies help skin look calmer and brighter through it, and help it keep that look for longer. In laboratory testing on human skin samples under UV-A and pollution challenge, treated samples showed lower levels of oxidatively damaged protein than untreated samples.*

Smoother, brighter skin Peptide technologies and botanical actives help improve the appearance of texture and radiance. With continued use, skin looks smoother, brighter and more luminous.

* Independent laboratory testing on ex vivo human skin explants. Comparison against untreated challenged samples. Not a study of people using the product; skin appearance was not measured. Data on file.

Apply two pumps to face and neck after cleansing, before your day cream and SPF.

KEY INGREDIENTS

Five advanced technologies This serum combines five cosmetic technologies, each chosen from a different area of skin longevity research. Together they help improve the appearance of firmness, elasticity and overall resilience.

Mini-Protein A next-generation biomimetic mini-protein, modelled on the skin's own signalling proteins. Formulated to help skin look firmer, smoother and more resilient, and to soften the look of lines.

Six Amino-Acid Peptide An advanced cyclic peptide, included for its role in one of the newer areas of longevity research: protein folding. As skin ages, damaged and misfolded proteins accumulate. Our interest in this peptide starts there. In the formula, it helps skin look firmer, more elastic and more resilient.

Biomimetic Peptide Modelled on the structural proteins of the skin's extracellular matrix - the components associated with hydration, elasticity and support. Helps improve the appearance of firmness, elasticity and density, for skin that looks firmer and more cohesive.

Centella Asiatica A biotechnology active grown by plant cell culture rather than conventional extraction, and rich in naturally produced bioactive molecules and plant peptides. Helps improve the appearance of firmness and elasticity and soften the visible signs of ageing, for smoother, healthier-looking skin.

Multi-Peptide Complex A natural polypeptide complex from winter pea - a single seed containing more than 400 peptides and polypeptides. Included for its antioxidant properties, it helps skin look smoother, firmer and more resilient.

Works Well With

Measured in a laboratory on human skin samples.

If we can’t measure it, we don’t claim it.

In independent laboratory testing on human skin samples exposed to UV-A and pollution, samples treated with this formula showed lower levels of oxidatively damaged protein, and higher Collagen I levels, than untreated samples. Collagen I is a structural protein that contributes to how firm and resilient skin looks.

These are measurements on excised human skin under laboratory challenge conditions, not a study of people using the product, and not a measure of how skin looks. Data on file.

A little too tacky for me
I love Romilly Wilde products, and I really wanted to love this serum too. Having used it for about three weeks, I haven’t seen any noticeable difference to my skin, although it may require longer use to see results. I also wasn’t particularly keen on the consistency, and it felt slightly tacky on my skin.

Love this new serum
Lovely, light weight, easily absorbed serum. Sits well under other skin care and makeup. I’ve been using it for a couple of weeks, my skin feels great and I think looks fresher.

Winning serum with dewy finish
The transparent, fragrance-free serum absorbs quickly and is the first thing applied to my skin after cleansing morning and evening. The formula is gentle on the skin and feels nourishing, hydrating, soothing. My moisturiser can be applied afterwards without pilling effect. It feels healthy and refreshing.

Frequently asked questions

Your skin is built on proteins. Collagen gives it firmness, elastin gives it bounce, and keratin holds the barrier together. Together they form the Proteome, the protein network that gives skin its structure and resilience. UV and pollution damage those proteins every day, long before ageing becomes visible on the surface, which is why Romilly Wilde formulates at that level rather than only treating what you can already see.

In an independent laboratory, on human skin samples, under UV-A and pollution challenge. Treated samples showed lower levels of oxidatively damaged protein, and higher Collagen I, than untreated samples. These are objective biological markers rather than a consumer perception study, so they measure what is happening in the skin, not how people felt about their reflection. Data on file.

Skincare rewards consistency, and this serum in particular. The changes begin beneath the surface, in the protein network, before they become visible. Use two pumps daily, morning and night, and from around week six look for firmness, texture and radiance. Most customers find it is the point at which other people start to comment.

Two pumps to face and neck after cleansing, morning and night. Apply it before your day cream and SPF in the morning, and before your night cream in the evening, so it sits closest to the skin. Allow it a moment to absorb before the next step. It layers comfortably with the rest of the system and with an SPF over the top.

The starting point. Most peptide serums are built to improve the look of the skin's surface, and this one was developed from research into oxidative protein damage, the process underneath. It combines a mini-protein modelled on the skin's own signalling proteins, a six amino-acid peptide from protein-folding research, and a biomimetic matrix peptide for the look of firmness and density, alongside Centella Asiatica grown by plant cell culture and a winter pea complex carrying over four hundred peptides. It is the anchor of the whole system, and if you only ever buy one Romilly Wilde product, this is the one.

Yes. Apply the Peptide Longevity Serum first, then follow with your vitamin C or retinol product.
