Did you know UV Rays
The Sun emits 3 types of ultraviolet (UV) rays
1. UVA rays contribute to burning, skin cancer, and wrinkling / premature ageing. They have a longer wavelength which means they penetrate deeper into the dermis or the base layer of the skin.
2. UVB rays are burning rays and the primary cause of sunburns and contribute to skin cancer. UVB rays have a short wavelength that reaches and burns the outer layer of your skin called the epidermis.
3. UVC radiation is blocked by the ozone layer whilst UVA and UVB both reach the Earth's surface and penetrate our skin. UCV rays are created artificially during certain industry processes such as welding.
80% of UVA rays pass through clouds. Sun protection is essential, even on very cloudy days.
