Many people do not understand the labelling on bottles of sunscreen, says the Royal Pharmaceutical Society.
A survey found one in five adults did not know that the SPF rating only tells you about protection from sun damage by UVB rays.
The SPF doesn’t tell you what protection the cream gives against the other damaging rays, UVA.
The UVA rating ranges from 0–5 stars. It shows you much UVA radiation is absorbed when you are using it.
The UVB protection rating is shown as a number from 2 to 50+ , called the SPF number. SPF stands for ‘sun protection factor’.
WHAT UV RAYS DO TO OUR SKIN
Both UVB and UVA rays from the sun can cause skin cancer.
UVA rays also cause skin-ageing and wrinkles.
To protect your skin the British Society of Dermatologists says you should look for a sunscreen with a high UVA and high UVB rating. Cancer Research UK recommends applying two tablespoons of sunscreen every two hours when out in the sun in the UK. It’s also a good idea to stay in the shade between the hours of 11:00 and 15:00 or to cover up when out in direct sunshine between these times.
