Collagen, meaning 'glue' in Greek, is a protein which holds your skin together, keeping it smooth and tight.
Collagen makes up to 75% of our skin, over 90% of our ligaments and tendons, and 35% of our bones. Other structures that are primarily made of collagen include our hair, nails and cartilage.
Alarmingly, we lose 1% of the collagen in our skin each year after the age of 20. By our 50's, we've lost over half the amount of collagen in our bodies! This decline results in wrinkles, fine lines, dry, blemished and thinning skin. Nails and hair become weak, brittle and lack lustre.
