I spent the first half of my life in sunny South Africa so this is a concept that is very close to home. In those days, sunscreen was something you applied at the beach. In fact, it was more likely to be referred to as “suntan lotion” giving the impression that you put it on in order to go out and get a tan. I can certainly recall being sunburnt as a child. This isn’t because my parents or teachers were careless or negligent. This was the norm. No one knew what SPF actually meant and so my hastily smeared factor 6 was expected to see me through the entire day. These days we are much more clued up about the dangers of the sun, particularly in regards to our children. Some adults still have a bit of catching up to do, but overall we’re getting better at protecting our skin in the sun and seeking early detection of sun damage from specialists.
Whilst sunburn is clearly a painful warning that your skin has been damaged by too much ultraviolet (UV) radiation, there are other undesirable consequences of excess sun exposure further down the line including premature ageing of the skin and, even more worryingly, skin cancer. After specialising in dermatology, my own personal interest in sun damage led me to undertake an extra year of study in order to complete a post-qualification fellowship in melanoma. People who have had sunburn are more than twice as likely to get melanoma than those who have not and the risk is even higher if you have had sunburn several times in your life. All good reasons to know how to protect your skin properly in the sun and how to spot the signs of skin cancer.
