As the UK heatwaves mark an unofficial start to summer, searches are up 900% over the past three months for ‘UV index’ suggesting people are turning to the resource before heading outdoors.
However, skincare experts are becoming increasingly concerned that many are misunderstanding what the UV index is actually designed for, with social media users increasingly using it as a guide for tanning rather than skin protection.
Over the past three months, searches relating to the UV index have surged by almost 900%, reflecting growing public interest in UV exposure and sun safety.
Melody Yuan, founder of Skin Cupid, the UK’s leading destination for authentic Korean skincare explains that while increased awareness of UV levels is a positive step, the information is often being used in the wrong way.
“The UV index is a measurement of the strength of ultraviolet radiation from the sun at a given time. It was created to help people understand their risk of sun damage and determine when additional sun protection may be needed.
However, we’re increasingly seeing people use the UV index as a tanning tool, checking when UV levels are at their highest in order to maximise sun exposure, this completely misunderstands the purpose of the scale.
A higher UV index doesn’t mean you’re getting a healthier tan, it simply means your skin is being exposed to more ultraviolet radiation, which increases the risk of sun damage.”
While tanning content has become increasingly popular across social media, Melody explains that many people fail to recognise the impact repeated UV exposure can have on long-term skin health.
“Many consumers still associate a tan with healthy, glowing skin, but from a skincare perspective, a tan is actually a sign that the skin is responding to UV induced damage.
Repeated exposure to UV radiation can contribute to pigmentation, uneven skin tone, dehydration, loss of elasticity, and premature skin ageing.
It can also place additional stress on the skin barrier, making skin more prone to sensitivity and irritation over time.”
In Korea, where daily SPF use is deeply embedded within skincare culture, sun protection is often viewed as a year-round habit rather than something reserved for holidays and heatwaves.
Melody says:
“One of the biggest differences between Korean and Western skincare approaches is the emphasis placed on prevention.
Rather than waiting for pigmentation, fine lines, or loss of firmness to appear, Korean skincare focuses on protecting the skin before damage occurs. Daily SPF is considered one of the most important steps in any routine, regardless of the weather or season.
This preventative mindset is one of the reasons why sunscreen remains such a central part of Korean beauty culture.”
As conversations around UV exposure continue to grow online, Melody believes consumers should focus less on tanning trends and more on understanding what UV levels actually mean for their skin.
“The rise in UV index searches is encouraging because it shows people are becoming more aware of environmental factors that affect skin health.
The next step is making sure that information is being used correctly. The UV index should be viewed as a tool for protection, not optimisation. Understanding when UV exposure is highest allows us to make better decisions about sun safety, helping to maintain healthier, stronger skin in the long term.”
With UV awareness continuing to trend across social media, experts hope consumers will increasingly see the UV index as an important skincare tool rather than a tanning guide.
