Type 2: Type 2 collagen primarily helps build cartilage, which is found in connective tissues. The health of our joints relies on cartilage made of type 2 collagen, which is why itâs beneficial for preventing age-associated joint pain or various arthritis symptoms. Type 3: Type 3 collagen is made of reticular fibers and a major component of the extracellular matrix that makes up our organs and skin.
Collagen occurs throughout the body, but especially in the skin, bones, and connective tissues. Some types of collagen fibrils, gram-for-gram, are stronger than steel. Collagen production declines with age and exposure to factors such as smoking and UV light. Collagen can be used in collagen dressings, to attract new skin cells to wound sites. Cosmetic lotions that claim to increase collagen levels are unlikely to do so, as collagen molecules are too large to be absorbed through the skin.
