There are many different brands of sunscreen and standards have improved dramatically in recent years. Gels dry quicker while creams may last longer in water. Sprays are good for balding heads and hairy chests. Make sure you get a broad-spectrum sunscreen with UVA and UVB protection. Dr Coleman recommend an SPF of 50.
SPF stands for 'sun protection factor' and tells you about protection from UVB radiation. A higher SPF gives you more protection. New EU recommendations mean that you will start to see changes on the labels of sunscreens. As well as the SPF number, sunscreens will be graded from low to very high protection to make the SPF guide easier to follow.
Whatever sunscreen you choose, be sure not to leave exposure to chance. "Don't look out the window to see if you need protection," says Dr Coleman. "In our changeable climate, the sun can appear on the cloudiest day, drawing us out to enjoy it.
"Make sure wearing one is part of your daily routine and remember to reapply regularly. Try to apply 20 minutes before going outside and re-apply every two hours, or more often if you swim or perspire."
