Even though it's technically not summer yet, it’s important to wear sunscreen when you're spending time outside. The sun is very strong in New Zealand, and we have one of the highest rates of melanoma (skin cancer) in the world. Our doctors are seeing an increase in the incidence of skin cancers and would love to see that change.
When used correctly, sunscreen can protect you and your family against sunburn and the damaging effects of too much UV radiation exposure. Sunburn, especially in childhood, is a risk factor for melanoma – and it doesn’t have to be sunny and warm for skin to burn.
Here are some tips to keep you and your family safe in the sun:
Use a broad-spectrum sunscreen of at least SPF30 and put it on at least 20 minutes before you go outside so it can be absorbed by the skin
Use a water-resistant sunscreen if you're going in the water.
Reapply sunscreen every 2 hours, even if the label says you can wait longer.
A zinc stick is good to use on a child’s nose, cheeks and lips.
Try and limit the time you spend in the sun from 10am to 4pm from now until April
Don’t just rely on sunscreen, as no sunscreen will completely shield you from the effects of ultraviolet radiation. You should also where a hat or cap that shades your ears and neck, where clothing (like a rash vest) to cover your skin, cover your skin and protect your eyes with sunglasses.
Be aware that you can also get sunburnt in the shade. This is because UV rays can reflect off concrete, water, sand and even from the inside of an umbrella.
Make sure you apply sunscreen to your shoulders, nose, ears, cheeks, and the tops of your feet.
Be especially careful to protect your children’s shoulders and the back of their neck when they're playing, as these are the most common areas for sunburn.
Store sunscreen in a cool, dry place, and check the expiry date before you use it –sunscreens generally only last for three years.
When first using a new sunscreen, try a small amount on a small area of skin to test it suits your skin.
If you have sensitive skin, look for hypoallergenic/low irritant sunscreens. Products containing titanium dioxide and zinc oxide may be the most suitable options.
You can get some great information about what type of sunscreen will best suit your skin by asking your pharmacist or discussing it with your GP next time you visit.
