Debunking the biggest sunscreen myths for a safer summer
Summer is almost here and as everyone flocks outdoors to soak up the sun, one thing that cannot overlook is sun protection.
Yet, despite the wealth of information available to us, many of us unknowingly fall victim to pervasive myths about sunscreen and skincare.
Whether it’s outdated advice, misunderstood science, or viral misinformation on social media, these myths can lead to poor sun protection habits and, ultimately, long-term skin damage.
To help you stay safe this summer and beyond, let’s bust some of the most common sun protection myths using insights from skincare experts, including Lamelle Research Laboratories.
Myth 1: You only need sunscreen when it’s sunny outside
Harmful UV rays are present every day, regardless of the weather.
While sunny days may seem more dangerous, overcast weather doesn’t block damaging UVA and UVB rays. UVA rays, in particular, penetrate clouds and even glass, contributing to premature skin ageing and DNA damage.
This means you’re exposed to harmful UV rays year-round, even during rainy or snowy weather.
Make applying broad-spectrum sunscreen a daily habit, no matter the season. Protecting your skin is a year-round commitment — not just a summer precaution.
Myth 2: Higher SPF means stronger protection
SPF measures time, not strength.
Many people believe that SPF 50 is significantly “stronger” than SPF 30 but that’s not how it works. SPF (Sun Protection Factor) indicates how much longer you can stay in the sun without burning compared to no protection.
For example, if your skin burns after 10 minutes without sunscreen, SPF 30 extends that time 30 times longer (300 minutes), while SPF 50 extends it to 500 minutes.
However, the difference in actual UVB protection between SPF 30 and SPF 50 is minimal. SPF 30 blocks about 97% of UVB rays, while SPF 50 blocks about 98%.
Myth 3: Babies and children shouldn’t use sunscreen
Sunscreen is essential for children’s sensitive skin.
It’s true that not all skincare products are suitable for babies and young children, but there are sunscreens specifically formulated for their delicate skin.
Babies under six months should be kept out of direct sunlight, but older infants and children need sun protection. Their skin is more vulnerable to UV damage, and childhood sunburns significantly increase the risk of skin cancer later in life.
Choose a sunscreen designed for kids, preferably one with mineral-based active ingredients like zinc oxide or titanium dioxide, which are gentler on sensitive skin. When in doubt, consult your paediatrician.
Myth 4: Darker skin tones don’t need SPF
All skin tones are vulnerable to UV damage.
A widespread misconception is that people with darker skin are naturally “immune” to sun damage. While melanin does provide some protection, it’s not enough to prevent sunburn or other harmful effects of UV exposure.
In fact, skin cancer in people with darker skin tones is often diagnosed at later stages, making it more dangerous.
Regardless of your skin tone, apply sunscreen daily to protect against UV damage, premature ageing and skin cancer.
Myth 5: Sunscreen contains harmful chemicals
Modern sunscreen formulations are safe and rigorously tested.
Fears about sunscreen ingredients being “toxic” or causing health issues have been widely circulated online, often without scientific backing.
While some research has raised questions about certain chemical filters like oxybenzone, the vast majority of sunscreens available today are safe and approved by regulatory bodies.
Additionally, mineral-based sunscreens (using zinc oxide or titanium dioxide) offer effective alternatives for those with concerns.
Choose trusted skincare brands with clinically tested formulations. If you have specific concerns, consult a dermatologist or look for mineral sunscreens labelled “reef-safe” or “chemical-free.”
Myth 6: Waterproof sunscreen means you don’t need to reapply
No sunscreen is truly waterproof.
“Waterproof” and “water-resistant” are often misunderstood. While water-resistant sunscreens can stay effective for up to 40–80 minutes in water, they will eventually wear off.
Sweat, swimming and towel-drying all reduce sunscreen’s effectiveness, so it’s essential to reapply frequently.
Reapply sunscreen every two hours, and immediately after swimming, sweating, or towelling off — even if your sunscreen is labelled as water-resistant.
Beyond SPF: Protecting your skin holistically
While sunscreen is a cornerstone of sun protection, it’s not the only defence your skin needs.
Protective clothing, wide-brimmed hats, and sunglasses are essential tools in minimising UV exposure.
Additionally, staying in shaded areas during peak sunlight hours (10am to 4pm) can significantly reduce your risk of sun damage.
