If you compare skin that has always been protected from the environment with the skin on your face, neck and hands you’ll notice a significant difference.
This difference is ‘premature’ ageing. Excessive exposure to the sun’s UV rays plays a major role. It is now known that low level inflammation in the skin can lead to the formation of enzymes that destroy collagen, elastin and hyaluronic acid. Any action that leaves the skin in a state of sub-clinical inflammation will cause damage to these vital structures in the skin.
Dehydration of the skin and the application of caustic ingredients such as acids have been identified as causes of inflammation.
