This is from the New England Journal of Medicine, which describes the subject as “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. The physical examination showed hyperkeratosis with accentuated ridging, multiple open comedones, and areas of nodular elastosis. Histopathological analysis showed an accumulation of elastolytic material in the dermis and the formation of milia within the vellus hair follicles.”
In plain English: this man was a truck driver for 28 years. The left side of his face was pummeled by constant sunlight day-in and day-out, UVA rays transmitting through the driver’s side window. The right side was comparatively shielded.
If you ever needed a reminder to wear sunscreen everyday (and maybe more on the right side of your body), this is it.
