Wrinkles and lesions that can lead to skin cancer are seen more often on the left side of the face, which is most exposed to sun when driving.
Dr Scott Fosko, chair of dermatology at Saint Louis University School of Medicine in the USA, says that more actinic keratoses (AKs) and wrinkles are seen on the forehead and left side of the face in his patients. The same is true of wrinkles. AKs are lesions that may lead to skin cancer.

Driving exposes these areas of the face to sun - especially UV (ultraviolet) A light, which can penetrate the windscreen. Dr Fosko believes even short drives can expose you to the sun in this way. His advice is that if you want to avoid skin cancer and stay looking youthful you should use sunscreen every single day. And do make sure that it's one which blocks out both UVA and UVB light. Wrinkles are not caused by aging, he adds, but by cumulative exposure to sun (which, of course, happens with aging). The best way to avoid wrinkles is to use a sunscreen.
