Open TikTok in summer and you’ll spot it fast. People lie in the sun, compare tan lines, and cheer each other on. That’s tanmaxxing, a trend about getting as dark as possible. Some creators add a shortcut to the mix: tanning melanotan injections. The pitch is simple.
Get deep colour with less time outdoors. Doctors and regulators say the shortcut has real costs, though. This guide explains what tanmaxxing is, why tanning melanotan injections keep showing up in it, and what to check before you trust a viral clip.
What is Tanmaxxing?
Tanmaxxing is a spin on “looksmaxxing,” a Gen Z trend about improving your appearance, and it urges people to chase the darkest tan possible. Followers track peak UV hours, skip sunscreen, and show off tan lines. Some go back to tanning beds. The creators behind this content are nicknamed “tanfluencers.”
Why It Spreads So Fast
A 22-year-old creator in Montreal said doctors’ warnings don’t reach people her age. She posts tanning photos with friends because the trend is popular and everyone joins in. Her idea was to have influencers promote sunscreen with a tint or glow. The lesson is simple. People copy people they like, not leaflets.
Why Doctors Push Back
Dermatologists say the protection from a tan equals about SPF 4, while they advise SPF 30 or higher. The World Health Organization lists UV radiation and tanning beds as Group 1 carcinogens, the same group as tobacco. Put plainly, a tan is a sign the skin has already been damaged by UV rays.
Why Tanning Melanotan Injections Trend Inside Tanmaxxing
Melanotan II is a lab-made substance that makes the pigment cells in your skin produce more melanin, so the skin looks darker. It is sold as injections, nasal sprays, and now oral drops, endorsed by influencers. The appeal is clear: less time in the sun. Online it goes by nicknames like “vacation peptide.”
TikTok has reportedly banned the #melanotan hashtags, so posts and products appear under vague labels. That makes tanning melanotan injections harder to spot, and harder to question.
Who Actually Uses Melanotan Injections?
You might guess teenagers. One 2025 study of 29 users says otherwise. The average age was 39, more than three in four were men, and many came to it through gym circles.
Melanotan Injections in the UK: What the Law Says
Melanotan injections in the UK count as unlicensed medicines. Selling them is illegal, but using or promoting them is not. That gap confuses many readers. The regulator (the MHRA) has also said nasal sprays that make no medical claims generally aren’t regulated as medicines. “Not regulated” doesn’t mean “safe.” Cancer Research UK says these products haven’t been tested for safety, quality or effectiveness.
The Risks of Tanning Melanotan Injections
Moles Can Change
One Reddit user said new moles started appearing almost at once during three months of use. Dermatologists add that moles can get lost among a tan and freckles, so changes are harder to notice.
Does it cause melanoma? That isn’t proven. A 2021 review suggested the higher melanoma risk seen in users may come from extra UV exposure. Still, a 27-year-old in the BBC’s investigation was diagnosed with stage one melanoma after a mole appeared eight months into injections, and she had also used sunbeds for two months. The safe takeaway is to check your skin.
You May Not Know What’s in the Vial
In one lab study, vials labelled 10 mg held between 4.32 and 8.84 mg. The BBC found some products contained over 100 unidentified substances. The dose on the label may not match what goes into your body.
Other Side Effects
Nausea, facial flushing and sexual side effects have been reported, along with abscesses at injection sites. In rare cases, a painful, prolonged erection called priapism needs emergency care.
The “Protective Tan” Myth
A 2024 study found one in three social media posts that mentioned skin cancer claimed melanotan protects against it. There is no evidence for that. A darker tan from melanotan injections doesn’t replace sunscreen.
Safer Ways to Get a Tanned Look
Cancer Research UK says fake tan or spray tan is the safer choice, and dermatologists suggest self-tanning products for a sun-kissed look. Add shade, sunscreen, and regular skin checks. A tinted sunscreen gives you a glow without the damage.
Final Thoughts: Check Your Skin Before You Trust the Trend
Tanmaxxing sells a look. The tanning melanotan injections side of it sells speed. Neither shows you the risks. Whether you searched for melanotan injections in the UK or just stumbled on a video, do three things today. Check your moles.
