Most of us know that UV radiation from the solar is public enemy number one as far because the skin is concerned. Overexposure leads to premature ageing and wrinkles as well as reduced immunity to illness, and probably even skin cancer. When our skin is exposed to loads of sunlight we produce abnormal elastin that causes the skin to stretch and collagen fibres start to interrupt down. In response to this we produce a large number of enzymes known as metalloproteinases or MMPS.
