The Alpine Peptide Complex™
Powered by The Alpine Peptide Complex™ — a proprietary Swiss formulation pairing Palmitoyl Tripeptide-5, Palmitoyl Tetrapeptide-7, Ectoin for environmental shielding, Niacinamide, stable Vitamin C, Madecassoside and Asiaticoside for repair, Hydrolyzed Hyaluronic Acid for hydration, and Swiss glacial water as the mineral matrix — backed by four years of laboratory development in Geneva.
Palmitoyl Tripeptide-5
a Swiss peptide that supports the skin’s own natural collagen.
Palmitoyl Tetrapeptide-7
a soothing partner peptide that smooths the look of fine lines.
Ectoin
a remarkable molecule from extreme environments that shields skin from environmental stress.
Argan Stem Cell Extract (Argania Spinosa Sprout Cells)
a modern plant stem cell active supporting the look of firm, dense skin.
Hydrolyzed Hyaluronic Acid
lightweight fragments for deep, comfortable hydration.
Vitamin C (Ascorbyl Tetraisopalmitate)
gentle oil soluble vitamin C for a brighter look.
Niacinamide (Vitamin B3)
supports the barrier and an even tone.
Madecassoside and Asiaticoside
a centella derived duo that calms and comforts.
Biosaccharide Gum-1
a soft moisture veil that leaves skin smooth.
What this serum doesn’t do.
Doesn’t lose potency the moment you open the bottle.
Youth Collagen Serum uses stabilised Vitamin C (Ascorbyl Tetraisopalmitate) and palmitoyl-bound peptides specifically engineered for shelf and in-use stability through a 90-day ritual. The bottle delivers what the laboratory tested, not a degraded version of it.
Doesn’t roll or ball when the cream goes over it.
The Hydrolyzed Hyaluronic Acid base settles cleanly — the 60-second waiting interval before applying cream is the only requirement. Tested with the full SÉRÈNE Suisse cream lineup.
Doesn’t sit on the surface like an oil.
The carrier matrix is water based with Hydrolyzed Hyaluronic Acid, not silicone based. Three to four drops absorb completely within sixty seconds when applied to Toner-primed skin.

Glacial Toner
The pH-priming step that allows the Palmitoyl Tripeptide-5 and Palmitoyl Tetrapeptide-7 peptides to penetrate.

Edel-Stem Rejuvenation Cream
Designed as a pair with this serum. The cream seals what the serum deposits and adds Edelweiss stem cell protection on top.

Magic Glow Eye Cream
The eye-area complement to the serum. Edelweiss and Vitamin C for the thinnest skin on the face, applied before the cream.
What customers are saying
The questions our skin team hears most.
The hydration and surface-plumping effect from the Hydrolyzed Hyaluronic Acid is immediate. Texture refinement typically becomes visible at two weeks. The treatment-grade benefits build over the full 90-day cycle — the Palmitoyl Tripeptide-5 and Palmitoyl Tetrapeptide-7 peptides require six to eight weeks of twice-daily use to produce visible density and firmness improvement.
Three things customers cite when they switch to this serum from another prestige peptide serum. First, every active is disclosed alongside the actual ingredient research. Second, the peptide architecture is dual: Palmitoyl Tripeptide-5 plus Palmitoyl Tetrapeptide-7. Third, the Swiss formulation standard and the price-to-concentration ratio.
For most serums, toner is genuinely optional. Skipping the Toner is the single most common reason customers report underperformance.
Yes — this serum complements both. Retinol works on cell turnover; this serum works on collagen synthesis. After an injectable or in-clinic treatment, resume from day one to capitalise on the elevated receptivity.
The formula is alcohol-free and contains no ingredients on the EU pregnancy-restricted list. The peptides are synthetic palmitoyl-chain peptides. We recommend confirming with your obstetrician for personalised guidance.
Yes. Alcohol-free. The Vitamin C is a gentle oil soluble form (Ascorbyl Tetraisopalmitate) rather than the more reactive l-ascorbic acid. Madecassoside and Asiaticoside provide active calming. If you are very reactive, begin with once-daily application for the first two weeks.
The 30 ml bottle is engineered for a 90-day twice-daily ritual at three to four drops per application. If your bottle is lasting noticeably longer than three months, you are likely under-applying.
Unopened products in their original sealed packaging may be returned within 30 days of delivery. For hygiene and safety reasons we cannot accept returns of opened products. Damaged or defective items are replaced or refunded. Return shipping is paid by the customer; refunds are issued within 7 business days of receipt.
Complimentary express delivery. Unopened returns within 30 days.
Every US order ships express, 2–4 business days. Unopened products in their original sealed packaging may be returned within 30 days of delivery; for hygiene and safety reasons opened products cannot be returned. Return shipping is paid by the customer.
