There is a proven association between the force of the sun’s rays and skin wrinkles. This has been known for a very long time, but what has been known for less long is why. We now know that the sun’s rays contain several kinds of ultra-violet light. Some are totally or partially blocked by the Earth’s atmosphere, but some get through too.
The vast majority of our facial wrinkles are the result of contact with UVA and UVB rays. We now know that it does not matter what the origin of those rays is, it is the UV rays themselves that injure skin, for that is what wrinkles are – damaged skin.
