Tan lines and sun baking are trending on TikTok. Here’s why experts are concerned – and what you should be doing instead.
If you’ve scrolled through your feed recently, you might’ve seen influencers flaunting their “perfect” tan lines – all achieved by baking under the sun – sometimes even during high UV index hours.
It’s like a step back in time to when tanning was considered cool, but here’s the harsh truth: there’s no such thing as a safe tan.
The TikTok tan line trend: What’s happening?
Across TikTok and Instagram, videos tagged #sunburnttanlines have racked up millions of views recently. These clips show users showing off their “tanning routines,” with some brazenly promoting apps that schedule tanning sessions based on UV levels.
Christine Morris, Manager Prevention & Advocacy at Cancer Council SA, says this behaviour is alarming – especially in Australia, where we have the highest melanoma rates in the world.
“These trends encourage people to expose their skin to harmful UV radiation on purpose, which increases their risk of skin cancer. It’s worrying that young people are prioritising aesthetics over their health,” Christine says.
Here’s why this trend is especially concerning:
- UV damage is invisible: You can’t feel UV radiation, but just 15 minutes of unprotected exposure can start damaging your skin.
- The stats don’t lie: In Australia, someone is diagnosed with melanoma every 30 minutes, and one person dies from it every six hours. It’s not just older people at risk, either – skin cancer can strike at any age.
But it’s not all bad news – Christine says some influencers are using their platforms to promote sun safety.
“We’ve partnered with fashion labels and influencers who are flipping the script, encouraging sun-safe behaviours in creative and engaging ways,” she says.
Debunking common myths about tanning and sunscreen
Misinformation is rampant online, so let’s set the record straight with Christine’s help:
Myth 1: Tanning makes you look healthier.
Fact: “Every time your skin tans, it’s a sign of trauma. Tanning doesn’t make you healthier; it damages your DNA and increases your risk of premature aging and skin cancer.”
Myth 2: Darker skin doesn’t need sunscreen.
Fact: “While darker skin has more melanin and offers some protection, it’s not immune to UV damage. Anyone spending time in the sun should practice sun-safe behaviours, regardless of skin tone.”
Myth 3: Spray sunscreen is just as effective as lotion.
Fact: According to Christine, sprays often don’t provide adequate coverage. “They’re harder to apply evenly, and you’re likely to miss spots. Lotions are more reliable.”
Myth 4: Sunscreen in makeup is enough.
Fact: “Makeup with SPF is great, but it’s not a replacement for proper sunscreen. You’d need to apply an unrealistic amount of makeup to get adequate protection.”
Myth 5: Sunscreen causes cancer.
Fact: “There is no credible evidence that sunscreen causes cancer. In fact, sunscreen is one of the most effective tools we have for preventing skin cancer. Claims to the contrary are unfounded and spread unnecessary fear.”

How to stay safe in the sun
If you want more facts, skip the hectic confusion of social media, and head to Skin Cancer: #EndTheTrend. This website is part of the Cancer Council’s campaign to stop suntans being normalised and challenge harmful attitudes about sun safety.
As the website makes all too clear, spending time in the sun without protection isn’t sexy – it’s actually #MakingMelonomas through a #KillerTan. Remember: When the #SunsOutCancersOut – no matter what TikTok tells you.
The one skincare tip you need to know
If the danger of disease and death isn’t enough to put you off, then what about the fact that skipping sun protection turns all your Sephora serums and fancy facials into wasted time and money?
For all the skincare girlies (and guys), Christine says focusing on sunscreen and sun-safe practices is essential.
“There’s no use investing in expensive skincare products if you’re not protecting your skin from UV damage first,” she says.
“UV exposure is responsible for up to 80 per cent of visible skin aging, and unlike a fine line, this damage is both permanent and preventable.”
So how can you join the #EndTheTrend movement? Here’s the sun-safe habits you need to know:
- Slip into sun-protective clothing that covers as much skin as possible – look for UPF-rated fabrics that block UV rays, or tightly woven cotton and linen.
- Slop on SPF50+ sunscreen generously and reapply every two hours, or after swimming or sweating.
- Slap on a stylish wide-brimmed hat to protect your face, neck, and ears.
- Seek shade during the day’s peak UV hours (usually 10am – 4pm). Even better, bring your own portable shade if you’re heading outdoors.
- Slide on a pair of UV-protective sunglasses to shield your eyes from harmful rays.

The good news: Changing the narrative
While the latest TikTok trend is concerning, there’s hope. Christine says arming people with scientific facts empowers them to feel good about their natural skin tone.
“Last year, we worked with fashion labels and influencers who embraced sun-safe fashion. They not only supported our message but kept promoting it beyond the campaign. It shows that when people understand the risks, they’re willing to make positive changes.”
Sun-safe practices are also becoming more stylish, as more people opt for UPF-rated clothing, wide-brimmed hats, and SPF-friendly skincare routines.
“You can look great and stay protected at the same time – it’s not an either-or situation,” says Christine.
