UV Rays through the window drastically age this truckers complexion.

This guy is 69 years old, but half of his face looks much, much older than that. He was a trucker and, for 28 years, his face received much more sunlight on the left side, resulting on premature aging. We all knew that being exposed to the sun makes you age prematurely, but seeing the dramatic difference in a single face is just stunning.

His condition is called unilateral dermatoheliosis or photoaging and it results from chronic exposure to the sun’s UVA and UVB rays. In his case, it only affected the left side of his face because of his work.

As he drove, he received many more hours of sunlight through the left window of his vehicle. The case was discovered and studied by Jennifer R.S. Gordon and Joaquin C. Brieva, dermatologists at Northwestern University, and published in the New England Journal of Medicine:

A 69-year-old man presented with a 25-year history of gradual, asymptomatic thickening and wrinkling of the skin on the left side of his face. He reported that he had driven a delivery truck for 28 years. Ultraviolet A (UVA) rays transmit through window glass, penetrating the epidermis and upper layers of dermis. Chronic UVA exposure can result in thickening of the epidermis and stratum corneum, as well as destruction of elastic fibers.

Since UVB and UVA can cause DNA mutations leading to skin cancer, the doctors recommended their patient to use sun protection and topical retinoids, as well as periodic monitoring for the apparition of skin cancer.

As the summer starts, this is a perfect reminder of the negative effects of excessive suntanning. If the risk of skin cancer is not enough for you, perhaps knowing that the sun will accelerate your ageing by a decade or two will stop you from being careless. Remember, if you are going to be exposed to the sun in any way—even if you are not at the beach or a swimming pool—use sunscreen! View original article here.
