If you ever questioned the power of the sun's rays and their ability to wreck havoc on the skin, view this photo of a 69-year-old truck driver, who for 28 years exposed the left side of his face through his truck window to the sun, reported blisstree.com.
While the right side appears smooth and unharmed aside from aging's natural toll, the right droops and is etched with deep wrinkles and blotted with age spots.
Sadly, the consequences of skin damage extend far beyond the physical, according to doctors Jennifer R.S. Gordon and Joaquin C. Brieva, who reported on the man's case of "Unilateral Dermatoheliosis" in the New England Journal of Medicine. The condition refers to the “thickening and wrinkling of the skin.”
"Chronic UVA exposure can result in thickening of the epidermis and stratum corneum, as well as destruction of elastic fibers," the doctors noted in their observations of the man's face. "This photoaging effect of UVA is contrasted with photocarcinogenesis. Although exposure to ultraviolet B (UVB) rays is linked to a higher rate of photocarcinogenesis, UVA has also been shown to induce substantial DNA mutations and direct toxicity, leading to the formation of skin cancer."
