At the same time, he lists a list of scientifically proven benefits of collagen for the body, which include improved skin condition, reduced joint pain, prevention of osteoporosis, growth of nails and hair, and muscle mass gain.
Vladislav Mitrokhin explains that collagen of animal origin is closest in composition to humans. It is also called “bovine”, as this substance is obtained from the skin of cattle. Since this species has large molecules, they cannot penetrate the protective layer of the epidermis due to their size if contained in cosmetics.
The easiest way for the body to absorb collagen is marine origin, which is produced from the cover and bone skeleton of fish. The main disadvantage of cosmetic products with marine collagen is the likelihood of allergic reactions, the expert warns.
In addition, preparations with it are more expensive, because marine collagen is sensitive to temperature changes, certain requirements must be observed during its production and storage.
