Indeed, excessive sun exposure is simply not worth it. You can bask in the warmth of summer, but will forever regret exposing your skin to the UV light without sunscreen.
Sunscreen
blocks and absorbs UV rays by combining physical and chemical particles.
Physical particles, for example zinc oxide and titanium dioxide, reflect UV
radiation from the skin. At the same time, chemical ingredients in sunscreen
react with radiation before it penetrates the skin, absorbing the rays and
releasing the energy as heat.
UVA and UVB
As
is well known by now, blocking and absorbing UV radiation is especially
important to combat both UVB and UVA rays. UVB radiation is the main cause of
sunburn and skin cancer. But UVA rays penetrate more deeply into the skin and recent
research has confirmed that these rays also play a significant role in skin
cancer development.
Broad-spectrum sunscreens provide clear information on product labels about protection against both UVB and UVA. And do consider SPF too. This refers to how much longer it takes for UVB rays to redden the skin with sunscreen compared to without sunscreen. So an SPF of 50 (which is what we recommend) means it will take 50 times longer for skin to burn while using the product than without the product.
Safe time outside
Consequently, with your sunscreen protection in place you can enjoy some time in the sun (until 10h00 and after 16h00) without worrying about excessive sun exposure. But outdoor activity enthusiasts should definitely use a water-resistant sunscreen. Alas, no sunscreen is completely waterproof. Those labelled water-resistant are tested to be effective for up to 40 minutes of swimming. Meanwhile, very water-resistant sunscreens stay effective for up to 80 minutes in the water. Stick to those time guidelines to protect your skin from excessive sun exposure.
Indeed,
sunscreen should be applied every day come rain or shine – about 30 minutes before
greeting the rays. Reapply every two hours and immediately after swimming or excessive
sweating.
Beware
though, even when it’s cloudy, up to 80 percent of the sun’s UV radiation
reaches the earth. Going unprotected on an overcast day can lead to skin
damage.
Check-ups
And don’t forget to schedule annual check-ups each and every year with your dermatologist. The earlier possible skin cancer is caught, the better the outcome.
