Swiss Science · Why Caviar?

The most nutrient-dense material in nature. Applied to the most complex organ in the body.

Caviar Extract is not a luxury ingredient in the cosmetic sense — it is a biologically precise one. The phospholipid, amino acid, and mineral profile of Acipenser Baerii roe mirrors human skin’s own cellular chemistry with a fidelity that no synthetic ingredient can replicate.

The Biology

Sturgeon roe is not glamorous by accident. It is nutrient-dense by biological necessity.

A fertilised sturgeon egg must contain everything required to build a fully functional organism from a single cell. That means the complete molecular toolkit for cellular construction: phospholipids, amino acids, nucleic acids, vitamins, and trace minerals in concentrations that are, by necessity, extraordinarily high. The phospholipid profile of Acipenser Baerii caviar is what makes it genuinely relevant to skin biology. Phospholipids are the primary structural component of the cell membrane — the lipid bilayer. The specific phospholipid composition of caviar roe (dominated by phosphatidylcholine, phosphatidylethanolamine, and phosphatidylserine) mirrors the composition of the human epidermal barrier with a precision that synthetic lipid blends cannot achieve. This is the correct meaning of “biomimetic”: not structurally analogous in a loose sense, but chemically near-identical in the components that matter for skin function. When the skin’s intercellular lipid matrix is depleted — by cleansing, environmental exposure, or age — caviar phospholipids can replenish it using the same molecules that were lost.

“The phospholipid profile of Oscietra and Baerii caviar roe is the closest naturally occurring match to human skin’s intercellular lipid matrix identified in the published literature. That is the basis of the biomimetic claim.”

The Profile

What caviar extract contains. And why it matters.

47+

Amino acids and peptides

Including all essential amino acids required for collagen and elastin synthesis. Proline and hydroxyproline — the two most critical for collagen triple-helix formation — are present at especially high concentrations in caviar roe.

~30%

Phospholipid content by dry weight

Predominantly phosphatidylcholine (PC) and phosphatidylethanolamine (PE) — the same lipid classes that form the dominant fraction of the human stratum corneum’s intercellular lipid bilayer.

A, D, B

Vitamin complex

Vitamins A, D, B1, B2, B6, B12, and E. Vitamin A supports cell turnover. Vitamin D modulates immune function in the skin. B-complex vitamins support enzymatic skin repair processes. Vitamin E provides direct antioxidant protection.

The Biomimetic Argument

Most ingredients work on the skin. Caviar works like the skin.

The skin barrier is a lipid-protein matrix. Its integrity depends on the availability of the right lipids in the right ratios: ceramides, fatty acids, and phospholipids arranged in lamellar layers between the corneocytes of the stratum corneum. This matrix is what prevents transepidermal water loss (TEWL), excludes environmental aggressors, and maintains the skin’s acid mantle. Most moisturising ingredients — including synthetic lipids, emollients, and occlusive agents — work by sitting on top of or within this matrix and mimicking its function. Caviar phospholipids are different: they are structurally compatible with the lamellar architecture itself. The skin’s own repair processes can incorporate them directly into the intercellular matrix rather than simply adding a layer above it.

Property	Synthetic lipid blends	Caviar phospholipids
Structural compatibility	Analogue — similar function, different structure	Homologous — same lipid classes, same structure
Barrier integration	Supplemental — adds above or between	Incorporable — integrated into lamellar layers
Amino acid delivery	Requires separate peptide addition	Native — full amino acid profile present in extract
Mineral cofactors	Not present unless separately formulated	Native — zinc, selenium, iodine present in extract

Precious Caviar Extract — Caviar of Switzerland

Responsible Sourcing

Acipenser Baerii. Sustainably farmed. Fully traceable.

The Siberian sturgeon (Acipenser Baerii) is a CITES Appendix II species. Wild harvest is prohibited in all Caviar of Switzerland supplier markets. Every gram of caviar extract used in our formulas comes from certified aquaculture operations — closed-system freshwater farming under controlled conditions. The roe is harvested as a by-product of the caviar food industry. Our extract is produced from roe that meets food-grade quality standards before it enters the cosmetic production stream. Nothing is wasted; nothing is wild-caught.

CITES Compliant

All Acipenser Baerii roe sourced from licensed aquaculture under CITES Appendix II framework. No wild-harvest supply.

Closed-System Aquaculture

Recirculating aquaculture systems (RAS) allow complete water management, eliminates ecosystem runoff, and enables full traceability from egg to extract.

Food-Grade Upstream

Extract produced from food-grade roe. Quality standards upstream of the cosmetic production process are the highest applied in any supply chain context.

Micro-Encapsulation

Active caviar compounds are micro-encapsulated in the final formula, protecting potency during shelf life and enabling time-release delivery into the dermis during application.

In the Formula

Caviar Extract works in every step of the ritual — at concentrations calibrated for each formula’s function.

The cleanser uses caviar extract to replenish the lipids lost during cleansing. The serum delivers it at the highest concentration, micro-encapsulated for dermal penetration. The eye cream focuses it on the periorbital zone at concentrations calibrated for the thinness of that skin. The moisturiser seals the active layers of the ritual and provides the sustained phospholipid reservoir. One extract, four applications, one complete biological system.

Step 01 — Cleanser

Micellar system binds impurities while caviar phospholipids immediately replenish the barrier disrupted by the cleansing process.

Step 02 — Serum

Highest active concentration. Micro-encapsulated for time-release delivery into the dermis, where the phospholipid matrix does its most important work.

Step 03 — Eye Cream

Periorbital calibration. The thinnest skin on the body receives caviar actives at concentrations appropriate for its unique lipid requirements.

Step 04 — Moisturiser

The sealing step. Caviar Lipid Complex forms the sustained phospholipid reservoir that maintains barrier integrity between ritual applications.
