Confused about SPF, zinc oxide, water resistance or reapplication? This guide answers the sunscreen questions Australians ask most, with practical advice for...
Discover four common sunscreen mistakes that could leave your skin exposed to harmful UV rays. Learn how to apply sunscreen correctly and choose the best protection for your skin.
Putting on sunscreen is one of the best things you can do for your skin—but simply applying it isn't always enough. Every summer (and winter too), we hear people say things like:
The good news? Most of these problems have simple solutions.
Here's how to get the most from your sunscreen and protect your skin properly.
If you've ever been burnt despite wearing sunscreen, the sunscreen itself may not have been the problem.
Most Australians apply only 25–50% of the amount needed to achieve the SPF printed on the label. For your face, neck and ears, aim for about a teaspoon. Less sunscreen means significantly less protection.
Even water-resistant sunscreen gradually wears away through:
Reapply every 2 hours when outdoors, and immediately after swimming, excessive sweating or towelling off.
No sunscreen blocks 100% of UV radiation. Even SPF50+ is designed to significantly reduce UV exposure—not give unlimited time in the sun.
The best protection comes from combining sunscreen with:
Sensitive skin doesn't necessarily mean you can't wear sunscreen. Often it's about choosing the right formula.
Some people may react to ingredients such as:
If your skin is easily irritated, look for products that are:
Your skin may simply prefer another formulation.
Depending on your skin type you might find better results with:
While irritation can happen, genuine sunscreen allergies are relatively rare. If you experience ongoing irritation, discontinue use and speak with your healthcare professional or dermatologist.
Few things ruin a day outside faster than sunscreen running into your eyes. Here are a few ways to help minimise it.
Water-resistant formulas are designed to stay in place better during:
Allow sunscreen time to settle before heavy activity. Avoid applying too close to your eyes where sweat can easily carry product.
If your eyes are particularly sensitive, look for:
A white cast is one of the biggest concerns people have about mineral sunscreen. Here's why it happens.
Ingredients such as Zinc Oxide sit on the skin's surface to help protect against harmful UV radiation. Because zinc is naturally white, some products may leave a visible cast.
Many modern zinc sunscreens use advanced formulations that rub in far more easily than older products. Some also use tinted pigments to better suit different skin tones while helping reduce visible white residue. Choosing the right formulation for your skin can make a noticeable difference.
There isn't one sunscreen that's perfect for everyone. Think about your lifestyle and skin type.
Mineral zinc sunscreen can be a great option because it's gentle and suitable for many sensitive skin types.
Choose a sunscreen with strong water resistance that can keep up with swimming, surfing, running and outdoor sport.
A lightweight sunscreen you'll actually enjoy applying is often the best choice. Consistency is more important than chasing the highest SPF number.
The best sunscreen isn't necessarily the most expensive one.
It isn't the highest SPF.
It isn't the trendiest.
The best sunscreen is the one you'll actually use every single day.
Daily sun protection helps reduce the effects of UV exposure, including premature skin ageing and the risk of skin damage.
