MINI SERIES: COLLAGEN #1


#1 What Is Collagen?

Collagen is the most abundant protein in the body and is found mainly in the skin, muscles, bones, cartilage and all the body's connective tissues. In the skin, collagen is responsible for its strength and elasticity. Collagen is made by the fibroblast cells found in the dermis. In addition to making collagen, fibroblast cells are also responsible for elastin production, as well as natural moisturising factors such as Hyaluronic acid. Fibroblast cells protect collagen by inhibiting collagenase (an enzyme that breaks down collagen) and also make pro-collagenases which destroy old and damaged collagen. Normal, healthy collagen (in lattice-type formation) is incredibly strong. It can be compared to a rubber band as it is extremely elastic and springs back when stretched.
There are several factors that contribute to collagen loss including: natural skin ageing and UV damage. Other key contributory factors to collagen loss include free radicaI damage and lifestyle (i.e. smoking, excess caffeine, alcohol and sugar consumption). If fibroblasts are damaged by UV rays or free radicals they will produce defective collagen.
If deep, long term damage to the structural proteins occur then the skin loses its tone and structure. Therefore it is important to safeguard your natural collagen by ensuring protecting your skin from UV damage and follow a healthy diet and lifestyle.
