Why It’s Vital to Wear Sunscreen…EVERYDAY!
by Dr Rabia Malik, Cosmetic Doctor and General Practitioner at Grace Belgravia.
Wearing sunscreen everyday should be a fact of life. Sun damage is the number one cause of skin ageing, as well as more obviously contributing to skin cancer. Living in London, I am often asked whether it’s entirely necessary to wear sunscreen every day, given that we see so little sun (!). The answer is yes and this is why.
There are three types of ultraviolet radiation from the sun – UVC which is the most damaging and is completely filtered by the earth’s atmosphere, UVB which is responsible for skin tanning and burning and promotes the development of skin cancer, but which cannot penetrate beyond the superficial layers of the skin and is largely blocked by the earth’s atmosphere, and UVA which accounts for 95% of the UV radiation that reaches the earth’s surface. UVA can penetrate into the deeper layers of the skin and is present even on cloudy days when there is no sun around. It is UVA which ultimately contributes to skin ageing.
Protecting the skin against the damaging effects of UVA is why I advise my patients to wear SPF 50 daily. However not all sunscreens are created equal. Many creams with an integrated SPF 15 are chemical based and often do not have specific UVA filters. My advice is to use a separate mineral based SPF (containing zinc oxide or titanium oxide) which acts as a physical barrier to the sun’s rays and should be the last step in your skincare regime every morning, before applying makeup. One of the best on the market is Skin Therapy by JuliaTHunter SPF 30 which is a 100% mineral sunscreen with the addition of ingredients to help with DNA Repair. If you make this part of your daily routine your skin will thank you for it!
