You can see sunlight and feel the sun's heat. However, you cannot see or feel ultraviolet (UV) radiation.
It’s a common misconception that sun damage only occurs in hot climates, as many people associate damage with the visible signs of sun exposure, i.e sunburn.
You may be surprised to learn that the sun’s UVA and UVB rays actually have different, yet equally harmful, effects on the skin. They also have the potential to cause damage in the winter, as well as in the summer.
UV radiation comes directly from the sun. It can bounce off surfaces such as buildings, concrete, sand, water and snow. It can also pass through light cloud cover.
Up to 90% of UV rays pass through clouds, so even when it’s cloudy, you need to protect yourself against the sun’s radiation.
UVA cause skin aging and leads to the skin feeling dry, wrinkly, roughened and saggy. In high doses, UVA can also cause the skin to burn, DNA damage in the skin, skin cancer and melanoma.
UVA rays are known as the ‘aging rays’ and are present during all daylight hours, regardless of the temperature. These rays can also penetrate glass and clouds; so don’t be fooled by cooler temperatures.
Cumulative exposure to UVA is known to assist in the development of skin cancer, as UVA rays penetrate the skin much more deeply than UVB.
UVA is a major factor in skin aging and is also the dominant tanning ray.
UVB tends to cause the skin to burn and also causes skin damage and skin cancer.
UVB is the burning ray. These rays do not penetrate as deep as UVA rays, however they can cause severe damage to the skin’s epidermal layers. These rays do not significantly penetrate glass and their strength can vary depending on the time of day. However, they can reflect off surfaces such as snow and ice, which means they can still cause damage in the winter.
When using sunscreens, always make sure it is broad spectrum, which means that it will block UVA & UVB. The SPF factor will indicate the amount of UVA and UVB rays it blocks.
Whilst UVC is the most dangerous form of UV rays, they are actually filtered completely out by the ozone layer so these rays never reach the Earth’s surface. UVC rays are also generated by electric welding equipment, so it is essential to be very well covered up and protected if you use such equipment.
It's a way of measuring the amount of UV radiation on the earth’s surface at solar noon on a particular day.

Your skin is your largest organ and has a long memory. Sun exposure and ultraviolet (UV) damage is cumulative throughout your life. Research shows that sun damage contributes to more than 90% of wrinkles, brown spots, premature skin aging as well as precancerous and cancerous skin lesions.
Limiting sun exposure is very important. As the UV rays cause the most damage to the skin.
It often takes many years and sometimes decades for the effects to become visible.
But the good news is that taking care of your skin from now onwards may be able to help you to reduce the probability of skin cancers and minimise skin aging.
