It is found naturally in bones, muscles, tendons and of course skin. Collagen plays a major role in the skin, ensuring proper functionality resulting in perfectly smooth young-looking skin. During the progression of ageing our body?s natural production of collagen in the skin decreases; skin gets thinner and is easier to damage, skin sags and wrinkles and signs of ageing become more visible. Although collagen can be found naturally in various parts of the human body, it is found in the highest percentage in the skin. Over 80% of the skin made up of collagen. Young skin produces more collagen thus keeping the skin looking young and healthy. Since collagen cannot be absorbed through the skin ingredients such as pomegranate extract, triple peptides, green tea and vitamin E are used to promote collagen and elastin production to smooth, firm and soften skin naturally.
