As someone who has worked with skin hands-on for 25 years as a celebrity esthetician and looks at faces all day, I can confidently tell you the answer is yes. Both men and women will have more sun damage, in the form of wrinkles and brown spots on the left side of the face, on the side that gets exposed to more UV exposure through the driver’s side window.
But when I saw this study from the New England Journal of Medicine, this certainly confirmed what I have seen to be true.
This 69-year old man had driven a delivery truck for 28 years causing one-sided photoaging (called unilateral dermatoheliosis) from exposing only half his face to direct sunlight for nearly three decades.

So yes, you can get more sun damage on one side of the face through a car window. This also brings awareness that you can get UV rays indoors – or in this case, inside of a car. Wearing sun protection 365 days a year, inside or out is essential to lessen sun damage.
Many people shy away from wearing sunscreen daily because they can often feel too heavy on the skin and clog the pores. There are great ones out there. Find one that is compatible for your skin type and wear it faithfully every day. Sunscreen is the best anti-aging product–EVER!
Daily Protection SPF 30 was just named “The Best SPF Product” by Elle Magazine!
Cosmopolitan Magazine says “Daily Protection SPF 30 is a sunscreen that WON’T cause acne.”
