HOW TO STAY SUN-SAFE THIS SUMMER
Although most people love the warmth and light of the sun, everyone knows too much sun exposure can significantly damage human skin. But, there’s much more you may be surprised to learn. Dr Claire Oliver (GDC) Medical Director at award-winning Midlands clinics Air Aesthetics shares some facts you may not know about sun damage and why protection should be non-negotiable.

UVA AND UVB: A DANGEROUS COMBINATION
There are 3 types of UV rays: A, B and C, however only UVA and UVB damage our skin. Both types can cause skin cancer:
UVB rays are the chief culprit behind skin reddening and sunburn, and vary in intensity depending on the weather, time of day and location. UVB rays mostly damage the skin’s outermost layers.
UVA rays are the chief tanning ray, primarily responsible for premature skin aging, like wrinkles, because it penetrates more deeply into the skin than UVB radiation. It ages the skin but contributes much less towards sunburn.
Up to 80% of the sun’s harmful UVA and UVB rays can penetrate your skin, even on cloudy days damaging the DNA— which can lead to skin damage and ultimately, skin cancer.
THE TAN-FACTOR
People tan because UV in sunlight causes the skin to produce more melanin or ‘tan’. Melanin is an attempt by your skin to
protect it from further damage. Melanin causes your skin tone to darken over 48 hours after UV exposure. The tan fades when new cells move to the surface and the tanned cells are sloughed off.
Some sunlight can be good as long as you have proper protection from overexposure. But, too much ultraviolet, or UV exposure can cause sunburn.
Evidence suggests that tanning greatly increases your risk of developing skin cancer. And, contrary to popular belief, getting a tan will not protect your skin from sunburn or other skin damage. The extra melanin in tanned skin provides a Sun Protection Factor (SPF) of about 2 to 4; far below the minimum recommended SPF of 15.
SKIN DAMAGE AND SUNBURN
Sun damage has short and long-term consequences. An immediately visible sign of sun damage is sunburn. In a mild form, this appears as red, burnt skin. In more severe cases, it is accompanied by blisters, as well as nausea and dizziness.
