Dermatologist says UK needs a “mindset shift” around UV sun damage

A leading dermatologist at University Hospital Southampton (UHS) is urging the public to “shift their mindset” around sun protection, warning the greatest risk of skin cancer comes from the cumulative impact of everyday ultraviolet (UV) exposure.

Dr Ella Seccombe, a consultant dermatologist at UHS, said it has become commonplace for people to take precautions only during period of intense sunshine and high temperatures.

However, while this does protect against burnt skin, many people “overlook” the impact of cumulative UV exposure and are at much greater risk as a result.

She is urging people to take more care of their skin on a daily basis – even with cloud cover – rather than only acting during sunny weather and summer months.

“Hot weather like this increases the immediate risk of sunburn, but the bigger issue is the damage that builds over time,” explained Dr Seccombe, who spoke out following a warning issued by the UK Health Security Agency (UKHSA) of extreme heatwave conditions expected across the UK this week.

“Most people think sun damage only happens on very sunny days or when they’re abroad but the reality is that the hidden and small everyday exposures here in the UK are the greater threat.

“We’re not always very good in the UK at recognising the risks of UV exposure, with sun protection often a knee jerk reaction to hot weather – but consistency is key to protecting your long-term skin health.”

While UV radiation is strongest during clear skies and high temperatures, exposure occurs whenever it is light outside – even on cooler or overcast days.

Even short periods outdoors, such as commuting, walking or exercising, can contribute to long-term skin damage when repeated regularly.

“You don’t need to be sunbathing to damage your skin,” Dr Seccombe said. “UV exposure happens day-to-day, often without people realising, and over time it increases your risk of skin cancer.”

Skin cancer is one of the most common cancers in the UK, with more than 20,000 cases of melanoma – the most serious form – diagnosed each year, and rates have more than doubled since the early 1990s.

Around nine in ten cases are preventable and linked to UV radiation.

“By the time we see visible signs of sun damage, it has often been building for years,” Dr Seccombe said.

“That’s why protection shouldn’t be something you only think about in a heatwave – it needs to be part of your everyday routine so we need a shift in mindset.”

People who spend extended periods outdoors – whether for work or leisure – are at greater risk due to repeated exposure over time, with outdoor workers receiving significantly higher levels of UV exposure than those indoors.

Dr Seccombe says particular care should be taken with areas most frequently exposed to daylight, including the face, neck, ears, arms and hands.

“These are the areas where we most often see the effects of long-term sun damage,” she said. “Using SPF daily – even outside of summer – can make a real difference.”

People are advised to use SPF 30 or higher on exposed skin year-round, reapply regularly during hot weather, check the UV index using weather apps, and cover up with hats, sunglasses and clothing where possible.

Alongside prevention, people are urged to check their skin regularly and seek medical advice if they notice any changes. Skin cancer, including melanoma, can spread if not detected early, but outcomes are significantly improved with early diagnosis.

“The earlier skin cancer is picked up, the easier it is to treat,” Dr Seccombe said.

“If you notice a new or changing mole, or anything unusual that doesn’t heal, it’s important to get it checked.”

As temperatures rise, the message from experts is clear – sun protection should not be seasonal.

“Protecting your skin should be part of your daily routine,” Dr Seccombe added.

“Simple habits like applying SPF to exposed areas every day can have a lasting impact on your health.”
