When you're picking up your holiday supplies over the coming weeks you will probably notice something different sitting on the sunscreen shelves.
These new sunscreens, with a sun protection factor (SPF) of 50+ (SPF50+), certainly sound as though they'll offer a lot more protection than those which have been available until now. But experts warn we shouldn't become careless about sun safety when using them.

"The amount of change between (SPF)30+ and 50+ is small, and people need to be aware that sunscreen is always the last line of defence."
Honorary secretary of the Australasian College of Dermatologists Dr Philip Artemi agrees, saying wide-brimmed hats, sunglasses and appropriate clothing, seeking shade and staying out of the sun in the middle of the day is just as important as ever.
The sun protection factor (SPF) of a sunscreen refers to the length of time it takes for skin to burn after you have applied sunscreen. It also refers to how much light it stops from reaching the skin.
"If you normally burn in five minutes (without sunscreen), with SPF30+ you have 150 minutes of grace; with SPF50+ you have 250 minutes," says Artemi.

the SPF rating is only reached when the sunscreen is applied correctly.

The good news for people with concerns about their skin or the chemicals in sunscreen is that there are many alternative products and ways to protect your skin.
"Really, there is no excuse not to protect your skin from the sun," says Artemi.
Sensitive skin: if you have sensitive skin or conditions such as rosacea or eczema, chemical-free sunscreens or those containing titanium dioxide or zinc oxide are less likely to cause problems. Look for products that are PABA-free.
