WHY YASTYCHNAYA
MORE THAN THE EGGS
Most caviar skincare uses only the loose eggs. Ours begins with yastychnaya, the whole roe sac, prepared to the traditional Russian standard and taken through our patented extraction. Egg, membrane and follicle wall together, separated into precise lipid and protein fractions.
One ingredient. Nothing diluted. Ten years of research behind every drop.
WHAT YASTYCHNAYA MEANS
THREE WAYS TO MAKE CAVIAR. ONE KEEPS IT ALL.
01 · GRANULAR
LOOSE EGGS
Individual eggs, screened from the roe sac and salted. The classic caviar on a spoon. The membranes and follicle walls are discarded.
02 · PRESSED
PAYUSNAYA
Damaged or over-ripe eggs pressed into a dense paste. Rich in flavour, but still the eggs alone, compressed.
03 · WHOLE ROE
YASTYCHNAYA
The whole roe sac, the yastyk, kept intact and prepared to GOST 32003-2012. Egg, membrane and follicle wall together. This is what we start from.
MEASURED, NOT ASSUMED
WHAT THE YASTYK ADDS
3×
SPHINGOMYELIN
The barrier lipid of skin, at three times the level found in the eggs alone.
8×
PHYTOSPHINGOSINES
The sphingolipid family that builds ceramides, eight times richer in the whole roe.
25–50×
STRUCTURAL PROTEINS
Follicle-wall and collagen-type proteins that granular caviar leaves behind.

PATENTED EXTRACTION
TEN YEARS TO PROVE IT
Caviar Clinic is a spin-out of Caviar Biotec, where a decade of proteomics and lipidomics mapped what the yastyk holds that the eggs alone do not.
From that work came our patented process. It separates the whole roe into a lipid fraction rich in phospholipids and sphingolipids, and soluble and insoluble protein fractions. Each is extracted, measured and kept apart, so every product carries a known profile.
