Food is a popular skincare ingredient these days, especially if it is considered exotic or expensive. Caviar is now cited in high-end skincare solutions as having super-charged abilities. Skincare brands say caviar contains protein, vitamins and minerals and has a cell structure identical to human skin cells. La Prairie has a Skin Caviar line and says caviar extract lifts skin and gives it immediate luminosity. Caviar extract contains omega-3 fatty acids, which are hydrating for skin. Others say you would be better off eating a jar of caviar or putting cod liver oil on your face because putting the extract into a face cream formulation causes it to lose much of its original properties.
