Wrinkles and Lines
Skin needs to be strong and elastic to look young. If it lacks collagen, its structure suffers. Wrinkles and fine lines form and make you look older. The older you get the less collagen your body produces so you need to take special supplements to improve your skin. Use sunscreens and avoid direct sun rays since they also affect skin.
Cartilage
Your cartilage protects your joints. If you wish to have healthy joints, you need to make sure that there is no lack of collagen in your body. With plenty of collagen your joins will be stiff, stable and strong. This thin tissue is found in the ear and nose too. Adjust your current diet or take collagen supplements if you feel pain in your joints.
