Facing the sun shouldn't be a gamble with your health. Recent product recalls and viral social media posts have sparked SPF fear, but understanding the facts about sunscreen is crucial for protecting your skin this summer. Let's dive into some common myths and uncover the truth.
In January 2026, after a consumer watchdog tested 20 popular sunscreen products and found that 16 didn't meet their SPF claims, the Therapeutic Goods Administration (TGA) stepped in. This led to recalls and a social media frenzy, with influencers warning against the use of sunscreen. But is this panic justified? Absolutely not.
"Australia has the highest rate of skin cancer in the world, with two in three Australians being diagnosed in their lifetime," says Christine Morris, Senior Manager of Prevention at Cancer Council SA. "Fortunately, skin cancer is almost entirely preventable. Sunscreen plays a crucial role in that protection – but it should always be the last line of defence in your sun protection routine."
So, what's the real story?
The initial testing focused on mineral sunscreens that shared a faulty base formula. Most of these products have been voluntarily recalled or paused. However, this doesn't mean all other sunscreens are ineffective. The TGA has approved over 900 sunscreens in the Australian market and continues to encourage their use when the UV index is 3 or above.
Sunscreen is a vital tool for preventing cancer, but it works best when combined with other sun protection methods.
Bonus: Sunscreen is your beauty secret weapon!
UV radiation doesn't just cause cancer; it breaks down the elastin in your skin, leading to wrinkles, sagging, and sunspots. Just 15 minutes of unprotected sun exposure can undo all the effort you've put into your skincare routine.
Using active skincare? SPF is even more critical.
Many skincare ingredients, such as retinol and exfoliating acids, make your skin more sensitive to the sun. If you're using these actives, SPF50+ is non-negotiable, along with a hat and sunglasses.
Sunscreen still works – but only if you use it properly.
Sunscreen isn't magic, but when used correctly, it's one of the most effective tools we have to prevent skin cancer, premature aging, and visible sun damage. The problem is, most people don't use enough.
How much sunscreen should you use?
According to the Cancer Council, you should use about one teaspoon (around 5ml) of sunscreen for your face, neck, and ears every time you go outside when the UV index is 3 or above. For full-body protection, the average adult needs around seven teaspoons in total: one for each arm and leg, one for the front of your body, one for your back, and one for your face, neck, and ears.
To make sunscreen effective:
- Apply sunscreen 20 minutes before going outdoors.
- Reapply every two hours, or more often if you're swimming, sweating, or towel-drying.
- Don't forget commonly missed spots like ears, hairlines, lips, hands, and the back of your neck.
"Sunscreen, even if it is reapplied regularly, cannot offer complete protection against UV radiation," says Christine. "That’s why we encourage everyone to use sunscreen alongside protective clothing, broad-brimmed hats, shade and sunglasses."
The five-step sun protection routine: Slip, Slop, Slap, Seek, and Slide.
- Slip on long-sleeved clothing.
- Slop on SPF50 or 50+ broad-spectrum, water-resistant sunscreen.
- Slap on a broad-brimmed hat.
- Seek shade.
- Slide on wraparound sunglasses.
Let's debunk some common sunscreen myths:
- "Makeup with SPF is enough." You'd need to apply way more than you normally would to match the SPF on the label. Use real sunscreen underneath.
- "Dark skin doesn't need sunscreen." UV causes long-term damage regardless of skin tone.
- "Fake tan protects you from the sun." It doesn't.
- "Sunscreen causes cancer." There's no credible evidence for that.
- "Sunscreen blocks vitamin D." Most people in Australia get enough vitamin D through incidental exposure.
