How to choose the best sunscreen?

As temperatures rise, more and more of us go out for a picnic or beach. However, anyone who has turned red after a few hours outside should know that sunscreen is essential.

The first thing to look at carefully is the sun protection factor, or SPF. This measures how much the cream will protect you against ultraviolet rays.

"SPFs are rated on a scale of 2 to 50+," says Prof. Brian Diffey of the British Association of Dermatologists. "We recommend an SPF of 30 or more as a satisfactory form of sun protection."

In addition to SPF, make sure the sunscreen also features a star rating.

"A sunscreen with an SPF of 30 and a rating of 4 or 5 stars is generally considered a good standard of sun protection, in addition to shade and clothing," says Diffey.

In theory, SPF 30 means that your skin will burn 30 times more. However, we rarely apply enough, or reapply often enough, which means we do not get the protection advertised in the bottle.
