This is why you should wear sunscreen

I came across this photo on the New England Journal of Medicine website the other day:

This is a 69-year old man who drove a truck 28 years. You can clearly see the difference between the left side which was exposed to the sunlight and the right side which was inside the cab. “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. Findings were consistent with the FavreRacouchot syndrome of photodamaged skin, known as dermatoheliosis. “

One additional note, pay attention to the expiration date on your sunscreen. Old sunscreen does not protect properly. A friend of mine found this out the hard way when she and her children got sunburned in spite of having put on sunscreen because the sunscreen she used was several of years old (we live in WA state where a bottle of sunscreen goes a long way). Most sunscreens have a 3-year shelf life but there are many factors that could possibly shorten that so if in doubt, get a new bottle… your skin and health is worth it.
