Collagen is one of the most plentiful proteins present in the bodies of mammals, including humans. It constitutes 25% of the total mass of human proteins. Some people refer to collagen as the glue that holds the body together. Without it, the body would, quite literally, fall apart. It works with keratin to provide the skin with appropriate strength, tightness, moisture, elasticity and suppleness and its degradation leads to wrinkles that accompany ageing.

From the age of 25, humans start to lose these features gradually, similar to muscles losing their strength, and bones diminishing in calcium.

After the age of 30, the atrophy of sebaceous and sweat glands starts in the body of nearly every human being and skin goes flabby, dry and wrinkles appear as a consequence of weakening collagen fibers which are the main component of the under-layer of connective tissue. Toxins and some enzymes damage protein fibers and the levels of micro - elements, fibroblasts and vitamins stimulating collagen production decrease in the body. The turnover of collagen still lasts but the older the body is the more degeneration predominate the synthesis.

Collagen takes part in vital functions of nearly all systems, organs and tissues. It is the main protein of connective tissue. It has great tensile strength and is the main component of ligaments, tendons, cartilage and bone.
