The agony of ageing – what are the effects on collagen?

As our skin goes through the natural ageing process, deep inside the dermis, the three major components of the extracellular matrix containing collagen fibres, elastin fibres and hyaluronic acid, undergo different structural and functional changes.

What does this mean? Well it means that external factors, such as stress, lack of sleep, smoking, diet and other environmental lifestyle factors, will affect the rate at which we age. Most of us are aware that the sun has an impact on our skin. UV rays from the sun can cause degradation of collagen and elastin fibres. As a result, the collagen density decreases each year with faster rate in photo-exposed skin. Collagen peptides are beneficial as a dietary supplement to reduce the damage that results from harmful UV radiation, so next time you plan a beach holiday, don’t forget to pack a collagen supplement, along with your sunscreen.
