I'm your face at 45, and researchers blame sunlight for about 80 per cent of what shows on me.
I'm writing from a shaded terrace with my hat on. I have a favour to ask. You've been watching the tanmaxxing videos. The UV index is pinned to your phone for the March trip to Tulum. This year you plan to skip the lotion and come home properly brown.
Canadians are especially good at this. We spend five months the colour of skim milk, then fly south and try to fix it in a week. Go on the trip. Come home golden, even. I just want the glow without the bill that arrives at my address in twenty years. I've found two ways to get it.
The short answer: Tanmaxxing means chasing the darkest tan you can, at peak UV, with no sunscreen. It speeds up wrinkles, rough texture and brown spots, and it raises your skin cancer risk. A tan is your skin reacting to injury. Self-tanner, a tinted mineral SPF and a more colourful plate give you the glow without the damage.
Is tanmaxxing bad for your skin?
Yes. The trend spread across social media in the spring and summer of 2026. It treats daylight like a workout: find the strongest hours, lie out in them, leave the bottle at home. Dr. Adam Friedman chairs dermatology at George Washington University. He told Spectrum News that people doing it are "accelerating and increasing the potential for skin cancers."
The tan itself is the clue. The Skin Cancer Foundation describes a tan as evidence of DNA injury to the outer layer of your skin. Your pigment cells darken to shield whatever is left, the way you draw the curtains after the sun has already faded the sofa.
The ageing part is slow. The FDA notes that the leathery texture and dark spots from unprotected UV may not show for a long time. In other words, they show up on me.
| The beach myth | What the evidence says |
|---|---|
| A base tan protects you | Barely. Tanned skin works out to about SPF 2 to 4 (FDA). ESTABLISHED |
| Tanning beds are gentler than the sun | No. Starting before 35 nearly doubles melanoma risk (2012 review of 13 studies). ESTABLISHED |
| A tan tops up your vitamin D | Hardly. Tanning delivers almost no vitamin D benefit (Skin Cancer Foundation). ESTABLISHED |
Twinsburg, Ohio, where the evidence wears matching outfits
Every August, a small town southeast of Cleveland fills with twins for the Twins Days Festival. They dress alike, compare notes and pose for a lot of photographs. Plastic surgeons from Case Western Reserve University have joined the crowd with a camera and a very long questionnaire.
They photographed 186 pairs of identical twins and asked each one about smoking, weight, sunscreen and time spent outdoors. Then a panel studied the faces side by side and guessed each twin's age. Same genes, same birthday, different habits.
The twin who had spent more time in the sun looked older, and the gap widened with every decade. Time outdoors without sunscreen pointed the same way. Sun-loving twins also carried more dark, patchy discolouration, the kind no concealer fully hides.
A second study, run by L'Oréal's research labs in Paris, sorted 298 women into sun-seekers and sun-avoiders and had experts grade their faces. Uneven pigment separated the two groups at every age. A softening jawline, by contrast, arrived with the years either way. The sun doesn't take everything from a face. Mostly it takes the evenness.
One honest caveat: the French study included only white women, so that 80 per cent figure may not hold for deeper skin tones. Darker skin has more built-in pigment, yet it can still burn, spot and develop skin cancer.
How do you get a glow without the sun?
Two ways, and neither needs a burn. The first comes from a bottle. Self-tanners use a sugar called DHA. It reacts with proteins in the dead outer layer of your skin and turns them brown. Chemists will tell you it is a close cousin of the reaction that browns toast.
The Canadian Dermatology Association says the shade starts to appear within a few hours and keeps deepening for a day or two. The tint lives in cells you were going to shed anyway. It leaves nothing behind for me. Smooth it on at night with a mitt, then wash your palms so they don't give you away at brunch.
The second glow comes from your plate, and it is the best surprise in this letter. In 2012, psychologists at the University of St Andrews in Scotland followed 35 people for six weeks. They measured skin tone with a light meter while the volunteers' diets shifted.
Those who ate more fruit and vegetables turned measurably more golden and rosy. The new tint matched carotenoids, the orange pigments in carrots, mangoes and sweet potatoes, rather than melanin, the tanning pigment. About three extra portions a day was enough for strangers to rate the skin in photos as healthier and more attractive.
The group was small and mostly fair-skinned, so treat this as EMERGING evidence. Still, a bowl of mango at breakfast costs less than any tube, and the rest of your body enjoys it too.
What I'd pack for the beach
The free part does the heavy lifting. Sit in the shade through the middle of the day and wear the wide hat. Let that UV index on your phone tell you when to cover up. A self-tan has no SPF of its own, so the bottled glow still needs a layer on top.
For your face, Andalou Naturals 1000 Roses CC Cream puts the tint and the cover in one step. The maker describes a sheer beige tint with broad-spectrum SPF 30 from 20 per cent zinc oxide.
For shoulders, chest and the backs of your hands, try ATTITUDE SPF 30 Adult Sensitive Skin. The fragrance-free mineral cream uses non-nano zinc oxide and is made to blend clear rather than chalky. Reapply after every swim.
How much you use matters as much as which tube you pick, and we worked out the real dose in our sunscreen filter story. For proof that daily SPF pays off on skin, the long Australian trial is in Collagen, On Trial.
Bring me home golden from a bottle and a fruit bowl, and I promise to look like someone who had a wonderful time. Love, your face, twenty years on.

Frequently asked questions
Should I wear sunscreen over self-tanner?
Yes. The Canadian Dermatology Association says self-tanning products do not protect your skin from the sun and are no substitute for sunscreen. It adds that DHA at 5 per cent or more may increase free-radical damage from sunlight for about 24 hours after you apply it, so cover up that day.
Are tanning injections and nasal sprays legal in Canada?
No. Injections and sprays sold for tanning usually contain melanotan, and Health Canada's April 2026 advisory lists melanotan I and II among unauthorized peptide products. Unauthorized drugs are illegal to sell in Canada and have not been checked for safety, quality or how well they work.
Is a spray tan booth safe?
Use some caution. The Canadian Dermatology Association notes that spray tanning booths are not FDA approved and advises avoiding inhaling the mist. Protect your eyes, lips and the inside of your nose with goggles, lip balm and nose plugs, or choose a lotion or mousse instead.
How long does a self-tan last?
About three to seven days. The colour sits in the outermost layer of dead skin cells, so it fades as your skin naturally sheds. Exfoliate gently the day before, moisturize dry spots such as knees and elbows, and top up every few days to keep the shade even.
