Sunscreen isn’t just a beach-day essential - it’s a daily non-negotiable. And yet, despite all the awareness campaigns, there are still countless misconceptions about how to use it correctly. From the belief that SPF is only necessary on hot days to the idea that makeup with sunscreen is enough, these myths could be putting your skin at serious risk.
Given that two in three Australians will be diagnosed with skin cancer by the age of 70, according to the Cancer Council, it’s time to set the record straight. Let’s bust some of the biggest sunscreen myths so you can keep your skin protected all year round.
Myth #1: You Only Need Sunscreen on Sunny Days
Think clouds have your back? Think again. Up to 90% of UV rays penetrate through clouds, meaning you can still suffer sun damage even on overcast days if your skin is unprotected. Elise Andrews, head of education at The Global Beauty Group explains: “UVA rays are present year-round and are the main culprits behind premature ageing and visible skin damage. Rule of thumb, if you can see daylight, your skin is being exposed.”
“Remember the UV index is at its highest usually between 10 and 3 (depending on the day and season) so try to avoid pro-longer exposure during these hours”. Get into the habit of applying your SPF as the last step in your morning skincare routine – rain hail or shine – and regardless of whether you plan to leave the house or not.
Myth #2: All Sunscreen Is The Same
Whilst the goal of all sunscreen is to protect your skin from sun damage, there are different forms with each working differently, depending on its ingredients and level of sun protection.
“Generally speaking, sunscreen can be broken down into 2 primary types: physical and chemical. Both types work effectively, but your choice should depend on your skin type, preferences, and how long you’ll be exposed to the sun”, Elise explains. “Physical sunscreens, (otherwise known as mineral sunscreens) contain ingredients such as zinc oxide and titanium dioxide, work by creating a barrier on the skin that reflects UV rays”.
Chemical sunscreens (with ingredients like avobenzone or oxybenzone) absorb UV rays and convert them into heat that’s then released from your body. Elise however doesn’t recommend these for people “prone to hyperpigmentation conditions such as melasma and PIHP as heat can worsen these conditions”. She continues, “Chemical sunscreens may also be a bit irritating for those with sensitive skin types”.
Its also important to note that chemical sunscreens oftentimes may contain ingredients that aren't reef-safe and are therefore so not ideal for when swimming at the beach.
Myth #3: A Higher SPF Means You Don’t Have to Reapply
Whilst it’s tempting to think SPF works like a bullet-proof shield, making you impervious to the sun’s rays, with a common misconception being the more you slather on, the more protected you will be from the sun’s exposure.
”The truth is, it’s important to remember that no sunscreen can give you complete protection against the sun, nor shield you from the UV rays entirely. Instead, sunscreen works by extending your skin’s natural burn time, so while you may feel “protected,” it doesn’t mean you’re entirely shielded” says Elise.
While SPF 30 filters out 97% of UVB rays, SPF 50+ blocks around 98%, a marginal difference. The real problem? Sunscreen breaks down over time due to sweat, oil production, and exposure to UV rays. The Cancer Council advises reapplying every two hours, especially if you’re swimming or exercising.
Myth #4: Makeup With SPF Is Enough Protection
Your tinted moisturiser or foundation with SPF might be a great addition to your routine, but it’s not a substitute for a proper sunscreen. To get the labelled protection, you’d need to apply at least a teaspoon-sized amount to your face alone - something most people don’t do. Instead, think of SPF-infused makeup as an extra layer rather than your only line of defence.
Myth #5: Sunscreen Blocks Vitamin D Absorption
Worried that daily sunscreen use will leave you vitamin D deficient? No need. Research published in the British Journal of Dermatology confirms that normal sunscreen use does not lead to vitamin D deficiency because incidental sun exposure (like walking to the car or sitting near a window) is enough for most people. The best way to balance sun protection and vitamin D levels? Get your dose through diet or supplements, not harmful UV exposure.
Myth #6: Darker Skin Tones Don’t Need Sunscreen
While higher levels of melanin provide some natural protection, they don’t make you immune to UV damage. Skin cancer may be less common in people with darker skin, but it’s often detected much later and at a more dangerous stage, according to the Skin Cancer Foundation. “No matter your skin tone, you need sunscreen,” says Dr. Shreya Andric, Sydney-based dermatologist. “UVA rays penetrate all skin types, causing ageing, hyperpigmentation, and long-term damage.”
Myth #7: You Only Need Sunscreen on Your Face
If it’s exposed, it needs SPF. Many people forget areas like the neck, ears, hands, and the tops of feet, which can be some of the first places to show signs of ageing. According to dermatologists, 90% of visible skin ageing is caused by sun exposure - so don’t stop at your face. Opt for a broad-spectrum sunscreen and don’t forget to reapply to all exposed areas.
Myth #8: Water-Resistant Means Waterproof
There’s no such thing as waterproof sunscreen. Water-resistant formulas provide 40 to 80 minutes of protection in water, but they still need to be reapplied immediately after swimming, sweating, or towel-drying. The Australian sun is notoriously harsh, so if you’re spending the day at the beach, pack your SPF and reapply religiously.
Myth #9: Sunscreen Causes Breakouts
Some people avoid sunscreen fearing it will clog pores and cause breakouts. But thanks to advanced formulations, there are now lightweight, non-comedogenic sunscreens designed for acne-prone skin. Look for oil-free or gel-based formulas with ingredients like niacinamide and zinc oxide, which not only protect but also help control breakouts and redness.
Myth #10: Sunscreen Alone Is Enough
Sunscreen is your best line of defence, but it’s not the only one. The Australian Cancer Council stresses the importance of following the Slip, Slop, Slap, Seek, and Slide rule:
Slip on protective clothing
Slop on sunscreen
Slap on a hat
Seek shade
Slide on UV-protective sunglasses
Combining sunscreen with other sun-safe habits offers the best protection against premature ageing, sunburn, and skin cancer.
Elise also stresses the importance of wearing and reapplying SPF when using active ingredients in your skincare routine (think Retinol, AHA’s and BHA’s like Glycolic, Lactic & Salicylic acids) as these are all photosensitive ingredients and can make your skin extra sensitive to UV rays. “It’s also vital to step up the SPF if you plan on getting any professional treatments with devices such as IPL machines, microneedling pens pre and post treatment” say Elise.
The Bottom Line: Sunscreen is a Year-Round Essential
Sun protection isn’t just for summer - it’s a daily habit that protects your skin from premature ageing, sunspots, and serious health risks. As Elise says, “Think of SPF as an insurance policy for your skin. With Australia having one of the highest rates of skin cancer in the world, proper sunscreen is non-negotiable.”
So, let’s ditch the myths and embrace the facts - because when it comes to sun protection, knowledge is your best defence. Stay safe, stay sun-smart, and make SPF your skin’s best friend. Your future self will thank you.
