Is sunscreen actually good for your skin, or could it be doing more harm than good?
This is the same question that keeps popping up every summer.
If you’ve been scrolling through TikTok or Instagram, you have probably seen a mix of advice, warnings and full-blown conspiracy theories. It can get confusing very quickly.
Sunscreen has always held the top spot in the skincare world.
Dermatologists worldwide agree that it is the most important step in any routine.
Yet there is still a surprising amount of chatter online questioning its safety and effectiveness.
“Social media influencers and online articles have once again been circulating myths about sunscreen, from its effectiveness to claims that chemicals contained in SPF actually lead to cancer,” explains Dr Alek Nikolic, renowned aesthetic medical practitioner and owner of SkinMiles.
And this misinformation does have an impact.
“A recent study by the American Academy of Dermatology showed that 37 per cent of Gen Z adults in the US only wear sunscreen when nagged to do so by others, and more than half are unaware of the negative effects of getting a sunburn, such as premature signs of ageing and increased risk of skin cancer,” he says.
So is sunscreen safe?
“First and foremost, sunscreen should be a non-negotiable part of your daily skincare,” says Dr Nikolic.
South Africa has some of the highest monitored UV levels in the world, which means the risk of sun damage here is extremely high.
“Fears about the potential long-term impact of ingredients should not interfere with sun-smart behaviour and the regular use of sunscreens,” he emphasises.
One ingredient that often sparks panic is oxybenzone.
It has been labelled a possible hormone disruptor when used in very large quantities, but evidence in humans remains lacking.
“According to Harvard Health, the organisations that have raised concerns about the use of oxybenzone typically cite studies done on rats. And in a 2017 study in the Journal of the American Academy of Dermatology, it would take an individual 277 years of sunscreen use to achieve the equivalent systemic dose that produced effects in these rat studies,” he explains.
For anyone who still feels unsure, ingredient-checking tools and reputable local brands can offer extra peace of mind.
Dr Nikolic also points out that sunscreens in South Africa are not classified as medicine, although responsible manufacturers follow strict guidelines from CANSA, the South African National Standard, the National Regulator for Compulsory Specifications and the Advertising Standards Authority.
What about darker skin tones?
Many people with darker skin believe they do not need sunscreen, but that is simply not true.
“The increased levels of melanin in dark skin provide some protection, but there are still frequent incidences of skin cancers in black South Africans, especially on the lower limbs, palms and soles of the feet,” says Dr Nikolic.
Everyone, regardless of race or skin tone, is vulnerable to UV damage.
Sunscreen formulas have levelled up
If you are still imagining thick, pasty lotions that leave you looking grey and shiny, it is time to let that image go.
“Gone are the gloopy swipes of lumo zinc that our mothers would lather on our faces and remain there for days. Today’s sunscreens feel more like serums or tints, but with the trusted efficacy of a traditional SPF sunscreen,” says Dr Nikolic.
Modern products are lightweight, non-oily and far more elegant on the skin.
Sun-smart is the only smart
“Myths about sunscreen safety aside, sun-smart behaviour this summer is critical. It is not possible to stay out of the sun all the time or cover up completely. And when we are exposed, even in overcast weather, sunscreen is our only line of defence. Those concerned about ingredients should consult a professional practitioner or doctor for sunscreen recommendation advice,” concludes Dr Nikolic.
At the end of the day, enjoying the sun and protecting your skin can absolutely go hand in hand.
With a good SPF and a bit of know-how, you can look forward to a glowing summer without the burn.
