I'm always telling my clients to make sure they're wearing SPF, especially during these summer months but you should be wearing it all the time ideally.
SPF protects us from the suns harmful ultraviolet rays, both UVA and UVB. UVB rays are what cause sunburn. However, UVA rays penetrate deeper into the skin. These rays can lead to long-term effects like wrinkling, premature ageing and other skin damage. Both types of ultraviolet rays can cause skin cancer.
The British Skin Foundation states that skin cancer is the most common form of cancer in the UK, and rates continue to rise. At least 100,000 new cases are now diagnosed each year, and the disease kills over 2,500 people each year in the UK - that's seven people every day.
In the summer it's particularly important because we generally spend more time outdoors when the weather is nicer, and we wear fewer clothes, exposing more of our skin. But, it's equally important all year round, including winter. Even if it's a cloudy day the UV rays penetrate the clouds and even penetrate windows. Snowy day? Yes, even then the rays are harmful, especially as they can reflect off the white snow and back onto us.
It's best to apply sun cream at least thirty minutes before you're exposed to the sun and should be incorporated into your everyday skincare routine. I love The Body Shop Skin Defense which has SPF 50 for in the summer, but for every day use the Green People Day Solution moisturiser has SPF 15, which is amazing.
