Besancon, France, During this society think that the window glass can protect the skin of a person from exposure to ultraviolet light. But it turns out ultraviolet rays can penetrate glass and cause skin wrinkles.
Most people will think their skin is protected from ultraviolet (UV) while driving or sitting by the window. However, this light can actually penetrate the glass and cause the exposed side of the face is wrinkled, especially around the eyes, nose and mouth.
Contained in the window glass could not prevent exposure to UVB sunlight, but could inhibit about 50 percent of UVA sunlight. This condition will be associated with aging and skin burns. Because of sun exposure happens every day can make skin age 7 years faster than unprotected skin.
The team from University College Hospital, Besancon, France conducted the first studies on certain parts of the face associated with exposure to sunlight and age.
The results obtained are female office workers or drivers will age faster in the side that always faces the sun and heat, although limited by the glass.
Researchers cite a 62-year-old woman is always driving 2-5 hours each day for 33 years to meet his clients. The researchers found the side of his face near the window of the car look 7 years older than the other faces.
“Low-dose of UVA is equivalent to one day in the autumn in England,” said Professor Trevor McMillan and Dr Sarah Allison from the School of Health and Medicine, Lancaster University, as quoted from Dailymail, Wednesday (09/08/2010).
This condition causes increased 50-fold in terms of expression of certain genes involved in premature aging of the skin due to exposure to UV radiation. The signs of premature aging that emerged include dark spots, wrinkles, rough skin and blood vessels are damaged.
“We believe that nearly 90 percent of the signs of aging caused by ultraviolet radiation from the sun and more than 95 percent of them due to UVA rays,” said Professor John Hawk, dermatology professor photobiologi.
