On a sunny afternoon, I used to be scrolling by means of social media after I got here throughout a video of a younger lady tossing her sunscreen right into a bin.
“I don’t belief these items anymore,” she stated to the digicam, holding the bottle up like a chunk of damning proof.
The clip had been seen over half one million occasions, with commenters applauding her for “ditching chemical substances” and recommending selfmade options like coconut oil and zinc powder.
In my analysis on the impact of digital expertise on well being, I’ve seen how posts like this will form real-world behaviour. And anecdotally, dermatologists have reported seeing extra sufferers with extreme sunburns or suspicious moles who say they stopped utilizing sunscreen after watching comparable movies.
Sunscreen misinformation created by social media influencers is spreading and this isn’t only a random development. It’s being fuelled by the platforms designed to host influencer content material.
In my e-book, The Digital Well being Self, I clarify how social media platforms should not impartial arenas for sharing data. They’re business ecosystems engineered to maximise engagement and time spent on-line – metrics that immediately drive promoting income.

Content material that sparks emotion – outrage, concern, inspiration – is boosted to the highest of your feed. That’s why posts questioning or rejecting science usually unfold additional than measured, evidence-based recommendation.
Well being misinformation thrives on this atmosphere. A private story about throwing out sunscreen performs nicely as a result of it’s dramatic and emotionally charged. Algorithms reward such content material with greater visibility: likes, shares and feedback all sign reputation.
Every second a consumer spends watching or reacting offers the platform extra knowledge – and extra alternatives to serve focused adverts. That is how well being misinformation turns into worthwhile.
In my work, I describe social media platforms as “unregulated public well being platforms”. They affect what customers see and consider about well being, however in contrast to public well being establishments, they’re not certain by requirements for accuracy or hurt discount.

If an influencer claims sunscreen is poisonous, that message received’t be factchecked or flagged – it can usually be amplified. Why? As a result of controversy fuels engagement.
I name this atmosphere “the credibility area”: an area the place belief is constructed not by means of experience, however by means of efficiency and aesthetic enchantment. As I write in my e-book: “Belief is earned not by what is understood, however by how nicely one narrates struggling, restoration, and resilience.” A creator crying on digicam about “toxins” can really feel extra genuine to viewers than a peaceful, scientific clarification of ultraviolet radiation from a medical professional.
This shift has actual penalties. Ultraviolet rays are invisible, fixed and damaging. They penetrate cloud cowl and hurt pores and skin even on cool days.
A long time of analysis, particularly in international locations like Australia with excessive pores and skin most cancers charges, present that common use of broad-spectrum sunscreen dramatically reduces threat. And but, myths spreading on-line are urging individuals to do the alternative: to desert sunscreen as harmful or pointless.

This development isn’t pushed solely by particular person creators. It’s embedded in how content material is designed, framed and offered. Algorithms prioritise quick, emotionally-charged movies. Interfaces spotlight trending sounds and hashtags. Suggestion methods push customers towards excessive or dramatic content material.
These options all form what we see and the way we interpret it. The “For You” web page isn’t impartial. It’s engineered to maintain you scrolling, and shock worth outperforms nuance each time.
That’s why movies about “ditching chemical substances” thrive, at the same time as posts on different points of ladies’s well being are shadowbanned or suppressed. Shadowbanning refers to when a platform limits the visibility of content material – making it tougher to seek out, with out informing the consumer – usually as a consequence of obscure or inconsistently utilized moderation guidelines.
The system rewards spectacle, not science. As soon as creators uncover {that a} specific format, like tossing merchandise right into a bin, boosts engagement, it’s replicated again and again. Visibility isn’t natural. It’s manufactured.

Those that throw away their sunscreen usually consider they’re doing the appropriate factor. They’re drawn to creators who really feel relatable, honest and unbiased — particularly when official well being campaigns appear chilly, patronising or out of contact. However the penalties may be severe. Solar injury accumulates silently, elevating pores and skin most cancers threat with each hour spent unprotected.
Sunscreen isn’t good. It must be reapplied correctly and paired with shade and protecting clothes. However the proof for its effectiveness is obvious and sturdy.
The true hazard lies in a system that not solely permits misinformation to unfold, but additionally incentivises it. A system by which false claims can enhance an influencer’s attain and a platform’s income.
To withstand dangerous well being developments, we have to perceive the methods that promote them. Within the case of sunscreen, rejecting safety isn’t only a private determination – it’s a symptom of a digital tradition that turns well being into content material, and infrequently income from the hurt it causes.
