Now that the summer sun is getting brighter and hotter, it’s important to think about protecting your skin. This 69-year-old man was a truck driver for 28 years, and the left side of his face shows the damage caused by long-term sun exposure through the driver’s side window. The photo was just released by the New England Journal of Medicine.
According to the Journal, 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 skin and destruction of elastic fibers. “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.”
The journal said doctors recommended that this patient use sun protection and topical retinoids and be monitored periodically for skin cancer.
