Sunscreens not only decrease the risk of getting skin cancer, but it also delays premature aging. Below you will find an image of a man published on the New England Journal of Medicine of a trucker with wrinkled face on the left side as a result of sun damage. The harmful ultraviolet rays from the sun hit the left side of the face for 25 years resulting in thickening of the skin, loss of elasticity and wrinkling. The picture published in 2012 is so powerful that I have to share it with you.
When I did a systemic literature review on sunscreen use years ago, I found out that certain people are staying longer under the sun after sunscreen use (which I advise against). While sunscreens offer some protection from the harmful UV rays, they do not entirely protect you. You must also minimize your exposure to the sun if you cannot avoid it as much as possible. If you have sensitive skin like me, try non-comedogenic sunscreens that are water-based because they won’t clog your pores as much. I also use sunscreens that are benzone-free which do not harm corals and marine life.
