When taken as a supplement, collagen benefits the joints. The body produces fluid around the joints to help them move freely, but as the body ages, the amount of fluid decreases, which can cause pain when the joint is flexed. Collagen supplements can help increase the amount of fluid around the joints, allowing them to move more freely.

Dermatologists and cosmetic surgeons use collagen in the treatment of scars. Acne, for instance, often leaves deep pitted scares on the face. Injecting a mixture of collagen directly into the skin around the scar helps raise the depression, making the scar less noticeable. The treatment, known as a tissue filler, has only a temporary effect, and the scar will return to its original condition after a few months.

Many lotions and face creams, especially those designed for overly dry or aging skin, contain collagen as an active ingredient,
Collagen benefits also extend to the hair and nails. A body’s hair and nails go through regular cycles that include both a growth and dormant period. Improper nutrition or poor health can extend the dormant period, keeping the hair and nails from growing or causing damage in the new growth. Collagen can help spur growth of the hair and nails and help keep them in a healthy condition.
