LONDON, April 5 – Scientists at the University of Liverpool have warned of the dangers of dermal exposure to the sun. They highlight a particularly sensitive area of the face that we forget too often when applying sunscreen.
While spring is just beginning to appear in the northern hemisphere, it can be tempting to fly into a sunny spot to bask in the heat. But the dangers associated with exposure to the sun should not be taken lightly.
Even if you do not intend to leave the sunscreen behind you, you may not apply it properly for full coverage, according to Liverpool scientists whose work was published in the PLOS One newspaper.
The researchers observed how people applied sunscreen products. They asked 84 students at the University of Liverpool to apply sunscreen and moisturizer with SPF (sun protection factor) on their face on two different occasions. The volunteers were then exposed to UV rays and photographed with the help of a UV-sensitive camera.
Awareness of the risks / benefits of sun exposure
On average, 11% of the face is not covered with sunscreen, compared to 17% when applying a moisturizer, reveals the study. The area around the eyelids was the most often forgotten area. The authors of the study warn that the face – especially the area around the eyelids – presents a higher risk of skin cancer.
"Special attention should be paid to the eyelid area when applying an SPF cream," said Austin McCormick, ophthalmology consultant and oculoplastic surgeon and co-author of the study, who stressed that filter the sunglasses. "
Although exposure to the sun is an excellent source of vitamin D, the researchers noted that most people spent long periods in the sun after using moisturizers with sunscreen. When they do it without covering their faces completely, it increases the risks.
The authors note that the results confirm those of previous studies and highlight the need to raise public awareness of vulnerable areas and sun protection strategies. – AFP-Relaxnews
