Sunscreen Savvy

Fun-in-the-sun tips, precautions and life savers

Although sunscreens are good at shielding you from the sun’s harmful untraviolet, or UV, radiation, they are far from perfect. Don’t let a dab of sunscreen give you a false sense of security. If you bake in the sun, you increase your risk of skin cancer and premature skin aging, even if you’ve used sunscreen.

To use sunscreen properly:

‘Apply it early, often and liberally.

‘Pick one with an SPF of at least 30.

‘Use a waterproof, broad-spectrum sunscreen that protects against both UV-A and UV-B.

‘Apply your sunscreen at least 30 minutes before you’re exposed to sunlight.

‘Use a full ounce to cover your body.

‘If you stay outdoors, repeat the application every two hours’or even sooner if you’re sweating or swimming.
