A truck driver face shows the devastating effects of sun exposure.
The left side of his face is deeply lined and wrinkled, while the right side is much smoother and younger-looking.
This is due to the fact that the left side of face was exposed to the sun through the side window of his lorry for 28 years.
His story is a stark reminder of the dangers of sun exposure, even for workers who don't consider themselves to be at risk.
Charities such as Factor 50 and Skcin are using these images to shock people into protecting themselves from the sun.
This could motivate others to start wearing sunscreen, sunglasses and protective clothing, and to seek shade whenever possible.
Truck driver's image was published in the New England Journal of Medicine.
