Collagen is the network which gives us our youthful appearance. As we age, these fibers in the skin begin to harden and fragment; the network starts to break down and our skin starts to lose its elasticity and show visible signs of ageing. Blood circulation to the skin decline; nutrients do not reach the surface, resulting in sallow skin. The fatty layer beneath the skin grows thinner so we look more drawn as our bone structure is more prominent. The reticular layer is vital to our skins health and appearance and so it is essential that it us looked after in order to prevent signs of ageing.
