UV rays increase premature skin ageing, burning, skin damage and skin cancer risk.
Sunlight is the main exposure to UV rays for most of the population. The intensity of the UV rays that reach the ground depend on:
Time of day
UV rays are strongest between 10am-4pm.
Season
UV rays are stronger during the summer and spring months; however, it is still important to remember that they can penetrate through clouds and are still here in winter months (especially UVA rays).
Surfaces
Water, sand, snow, pavements can all reflect UV rays which increases exposure.
Altitude
The higher up you are above sea level, the more UV rays.
Distance from the equator
UV exposure decreases as you move away from the equator.
Conclusion
UV exposure depends on all of these factors, along with how long skin is exposed to UV rays and if the skin is protected (sunscreen or clothing).
However, it’s not just the sunshine which causes exposure to UV rays. Tanning booths/sun-beds are a source of UV rays too, and mainly omit UVA rays. The amount of UV rays in a tanning booth depends on the lamps used, duration used, and frequency. Previously tanning booths/sun-beds were seen to be safe, however, we now know this is not true.
Ways you can protect your skin:
- Use a broad spectrum sunscreen (UVA and UVB protection) like our SPF 30 Face Serum, you can read more about the importance of SPF here.
- Stay in the shade if outside (especially during midday hours)
- Wear a hat
- Wear sunglasses
- Wear clothing that covers you
- Avoid using tanning booths/sun-beds
