For skin that looks rested and full, not thin and tired.
Built on salmon-derived polynucleotides at 5% — the top of the range its supplier has tested — with MossCellTec™ No. 1 at its studied 2%, PhytoCellTec™ Swiss apple fruit cell culture, biotin and hyaluronic acid. Applied at night, when your skin has the face to itself.

The corner of the eye, where it shows first.
Where skin creases when you smile and, lately, stays creased a moment longer. MossCellTec™ No. 1 sits here at 2% — exactly the level its own studies used. Measured against placebo over 28 days, the appearance of crow’s-feet wrinkle depth fell 15%.
And in the most punishing test in its file — 23 women through a Seoul summer, moving between outdoor heat and dry air-conditioned offices — every one of the 23 recorded a significant increase in skin hydration on the treated side within 14 days, and 91% recorded lower water loss. That is a responder rate inside one clinical cohort, not a guarantee, but it is a hundred per cent of a real group under conditions worse than your commute.
Alongside it, PhytoCellTec™ Malus Domestica, the world’s first plant stem-cell active in cosmetics and patented in five countries: in its maker’s four-week study, crow’s-feet wrinkle depth fell 8% at two weeks and 15% at four — that study ran at 2% and this serum carries 1%, which we print rather than round away.
And the salmon-derived polynucleotide complex behind in-clinic renewal treatments, at 5%. Made in Carros, France. Results refer to the appearance of skin.
The 5%, printed on the box.
DNA Gel PH™ at 5.00% — high-purity polynucleotides from salmon soft roe, fragmented to around 110 kDa: large enough to hold their water-trapping structure, small enough to work. Five per cent is the maximum concentration its supplier has ever tested, which is an unusual place for a brand to end up.
Watch the units when you shop this category. Competitors print numbers like “10,000 ppm”, which sounds enormous and is one per cent of a raw solution. Our 5% delivers 1,500 ppm of polymerised sodium DNA into the finished serum. In the supplier’s evaluation on 10 volunteers over 8 days, it produced a significant increase in the mechanical elasticity and suppleness of skin.
Contains salmon-derived DNA. Not vegan. Not suitable for anyone with a fish allergy. We put that on the front of the page rather than the bottom of the ingredient list.
One number here does not flatter us. It is printed anyway.
If disclosure at this level reads as unusual, that is a statement about the category, not about us.
- Evidence tier
- Supplier research — Mibelle Biochemistry’s ingredient studies, not independent studies of this finished serum.
- Where the clinical weight sits
- MossCellTec™ at 2% and DNA Gel PH™ at 5% — both at, or at the top of, their studied concentrations. The crow’s-feet and hydration numbers on this page come from those two.
- The honest line
- PhytoCellTec™ is included at 1% where its study used 2%. We print the gap rather than round it away, and it rises on the next production run.
- Published with your order
- Full INCI, allergens first: contains fish — not vegan.
Night. After cleansing, before moisturiser.
Clean, dry skin — the last face of the day.
A few drops pressed in, before moisturiser.
Nothing to layer, nothing to time. The night step stands alone.

5%, 2%, 1%. Every concentration printed.
Polynucleotides are salmon-derived — which is why this serum is not vegan, and why we say so on the front of the page instead of the bottom of the INCI.
- Salmon polynucleotides — 5% — the renewal compound behind in-clinic treatments, at the top of its supplier’s tested range
- MossCellTec™ No. 1 — 2% — the maker’s level, exactly — this is where the clinical weight sits
- PhytoCellTec™ — 1% — Swiss apple fruit cell culture — its study used 2%, and we print that too
- Biotin + hyaluronic acid — present at trace level — named on the label, claimed nowhere
Every active, and how much of it is in the bottle.
Ingredient lists use INCI names, which is why a hero active can hide inside words like “isomalt” or “malus domestica fruit cell culture extract”. So here is the plain version: what we call each active, and how much of it is in the finished serum.

- MossCellTec™ No. 1 · 2.000%

PhytoCellTec™ Malus Domestica was the first plant stem cell active in cosmetics, and it is patented in five countries. In its maker's four-week study with 20 subjects, a 2% cream applied twice daily to the crow's feet area reduced wrinkle depth by 8% at two weeks and 15% at four, measured by the PRIMOS system.
One number here does not flatter us: PhytoCellTec™ sits at 1% where that study used 2%. We print it anyway, and it rises on the next production run. The clinical weight in this formula is carried by MossCellTec™ at 2% and DNA Gel PH™ at 5% — both at, or at the top of, their studied concentrations.
Applied at night. Made in Carros, France. The research is Mibelle Biochemistry's and Sederma's own, into the ingredients rather than into this finished serum.
Contains fish. The polynucleotide complex is salmon-derived, so this serum is not vegan and is not suitable for anyone with a fish allergy. Patch test 48 hours before first use. For external use only. Avoid the eye area. Results refer to the appearance of skin and vary between individuals.
