Look for a sunscreen that blocks both UVA (long) and UVB (short) rays, has an SPF of at least 30 and is water-resistant. An antioxidant is an essential active ingredient for all sunscreens because it protects your skin from free radicals that damage DNA and can cause cancer.
It is recommended that you buy separate sunscreens for children and adults. Sunscreens for children are formulated without ingredients that could cause skin irritation – they generally contain ingredients that are not absorbed by the skin at all. Make sure you buy new sunscreen every season.
When should I apply it?
• Apply sunscreen to dry skin 20 minutes before going outdoors to give the ingredients time to activate.
• Reapply every two hours, or after swimming or exercising.
• Wear sunscreen every day – even on cloudy days up to 80% of the sun’s rays can penetrate your skin. UVA rays are not filtered by clouds.
• Avoid the sun between 11 am and 4 pm.
• Wear protective clothing.
• Babies and infants should not be directly exposed to the sun.
