Learn not to burn
Do not rely upon sunscreens as your only form of skin protection. Use in conjunction with natural protection ie. Staying in the shade, wearing protective clothing, hats and sunglasses.
Sunscreens labelled " SPF 30+, broad spectrum (blocks out UVA and UVB) and water resistant" will provide the best protection. Water-resistant sunscreens should be used for swimming, outdoor activities and in humid climates. It is vital to apply sunscreens to dry skin at least 20 minutes prior to sun exposure and to reapply after swimming. Leave a light film of sunscreen on the skin - don't rub it in.
Sun Damage & Children
Since children do not understand the dangers of UltraViolet Radiation they need protection. Children need special care as they spend more time outdoors than adults and can burn more quickly as they have very little melanin (skin pigment) to protect them. Australian research indicates that 80% of lifetime sun exposure occurs before age 18. Babies - even when in the shade - can burn very quickly.
Alarmingly, as few as 6 childhood sunburns significantly increases the risk of melanoma cancer later in life. Started early and followed consistently sun wise behaviour will become a sound healthy habit- as routine as fastening seatbelts or brushing teeth!
