Sunscreen is important Clothing, hats and shade are the best methods for protecting skin from ultraviolet (UV) radiation but any remaining exposed skin can be protected by applying sunscreen. It is important not to rely on sunscreen as the only form of sun protection. No sunscreen offers 100% protection from UV radiation.

How sunscreen works
Sunscreen filters out most UV radiation before it reaches the skin. The ingredients in sunscreen absorb UV radiation and can also scatter or reflect UV radiation away from the body, depending on the type.

Broad spectrum sunscreen filters UVA and UVB radiation. All sunscreen products sold in Australia are approved by the Therapeutic Goods Administration as safe and effective.

Sun Protection Factor (SPF)
The SPF rating indicates the level of protection offered by the product. Products rated SPF 30+ provide maximum protection because they filter 96% of UV radiation. Many people do not use enough sunscreen or do not re-apply it every two hours so they may not get sufficient protection.

Choosing a sunscreen
Choose broad spectrum SPF 30+ water resistant sunscreen. Price does not necessarily indicate quality. All sunscreen sold in Australia complies with the Australian/New Zealand Standard for sunscreen products. For sensitive skin, try a fragrance-free product or one for toddlers. Sunscreen comes in creams, lotions or gels and all work equally well.

Expiry dates
All sunscreen products should have an expiry date but most will last from two to three years if stored below 25°C. Do not use if past the use by date.

Applying sunscreen
Apply generously - adults should use about a teaspoon for each limb and ½ teaspoon for the face, ears and neck. Most people do not apply enough sunscreen. Apply sunscreen 20 minutes before going outdoors to clean, dry skin, which gives it time to bond to the skin. Re-apply sunscreen every two hours or more often if you are swimming or perspiring.

Never use sunscreen to extend the time you would normally spend in the sun.

Babies and toddlers
Babies under one year old should not be exposed to the direct sun. Avoid taking babies outdoors between 10 am and 3 pm if possible. Natural protection like clothing and shade is best, but small amounts of sunscreen can used on areas not protected by clothing.

Sunscreens labelled for babies and toddlers contain the same sun screening chemicals as other products. Generally the only difference is that they use a gentler base and do not contain perfumes.
