Skin care creams based on Caviar had a tumultuous success lately because they improve the appearance of the skin. Evidence provided by manufacturer seem to support the positive effects associated with the treatment, but no sound scientific studies have yet been conducted that confirm its efficacy. Using current claims as a working hypothesis, how would caviar work on our skin?

The cosmetics industry provides us with new ways to launch novel active ingredients of animal, vegetable, mineral or synthetic origin. Recent in this list of is the anti-ageing facial creams and serums based on caviar extract. Companies worldwide recognized the need for their high-end products and launched a full line of treatments with caviar extract on the market. Cheaper copies soon arrived on the market who took advantage of the fashion for this new natural ingredient.

What initially started as a competition on skin care products has extended now to include hair treatments based on caviar.

Caviar extract is obtained from the eggs of the sturgeon (Acipenser sturio), which measure around 2-2.5 mm in diameter. The precious ingredient is extracted by manufacturers using a complicated process.

The main nutritional components of caviar go hand in hand with its cosmetic properties, as caviar extract contains:

  • Carbohydrates such as glucose, fructose, sucrose and glycogen.
  • Lipids or fats with a high content in polyunsaturated fatty acids, waxes, sterols, lecithin and phospholipids.
  • Proteins containing 17 amino acids: isoleucine, lysine, methionine, cystine, phenylalanine, tyrosine, threonine, tryptophan, valine, arginine, histidine, alanine, aspartic acid, glutamic acid, glycine, proline and serine.
  • Vitamins A, D, B1, B2 and H.
  • Minerals and trace elements such as sodium, potassium, calcium, magnesium, iron, phosphorus and sulphur.

The comprehensiveness of the list of basic nutrients, rich in proteins, explains why caviar extract is a potent cosmetic ingredient.

The most important properties of caviar extract are its moisturizing, nourishing, anti-ageing, vitaminizing and protective qualities, all of which help reverse skin ageing processes. The carbohydrates moisturize, the proteins provide nutrition, while the highly unsaturated lipids have effects on dry and ageing skins and the vitamins and trace elements revitalize the skin.

In tests performed by manufacturers, parameters such as skin smoothness, firmness and micro-wrinkles were assessed dermatologically in a study with 20 human volunteers aged between 35 and 70 years.

Over the period of a month, ten of the subjects applied 2.5% caviar extract cream twice daily on one half of the face and the same cream without the caviar extract on the other half of the face. The other ten subjects did the same with 5% caviar extract cream.

The results were rated as good for the 2.5% cream and very good for the 5% cream. The effect of the placebo creams with no caviar extract was minimal.

Even though caviar has a tremendous commercial appeal as a luxury food, only time and demonstrated results will stand the claim of having positive effects as skin care treatment.
