If ‘lifespan’ is the time you’re alive and ‘healthspan’ the years you’re disease-free, then ‘hotspan’ is the period you’re attractive and vibrant. Want to increase yours? Experts share their tips

Forget 12-step skincare routines, red light therapy and injectables – the single most important thing you can do for your skin is wear UV protection. “Not just sun protection, but UV protection, every single day, regardless of weather or season,” says Dr Jennifer Owens, resident aesthetic expert at the Reborne Longevity clinic in London. “Up to 90% of visible skin ageing is caused by UV exposure – nothing else comes close in terms of impact.”

Beware the misguided logo, warns Guardian fashion columnist Jess Cartner-Morley: “Never, ever wear a sweatshirt or, worse, carry a basket with a slogan that includes the words ‘dance’ or ‘love’. Be cautious of words in French. These are the style equivalent of having a ‘Live, laugh, prosecco’ poster in your kitchen. Sorry, but you cannot buy youthful insouciance at M&S.”

Want to look instantly better without spending a penny? Standing up straight makes you look younger – and thinner – says Nick Finney, personal trainer to celebrities including Jennifer Lopez: “Our posture suffers with age, due to a combination of weakness, atrophying muscles and tightness. The solution is to strengthen all the muscles in your posterior chain [the rear of your body] while making sure that the muscles at the front have enough mobility to allow them to pull your back upright – tight pectorals will pull your shoulders forward.” Strengthen your posterior chain in the gym by perfecting Romanian deadlifts and horizontal rows.

People get hung up on wrinkles and middle-age spread, but dodgy teeth are far more ageing, says Sali Hughes,the Guardian Saturday magazine’s resident beauty expert: “Teeth that are discoloured, significantly crooked or even missing are very ageing and so, conversely, a well cared-for mouth can take years off.”

According to Ten Dental’s Dr Jenni Rawes: “As we age, enamel naturally wears down, revealing more of the dentine underneath, which is a darker, creamier colour. It’s also more porous than enamel, so absorbs staining from food and drink far more readily, making teeth look darker still over time. Brightening the smile has a huge effect on how youthful and well someone appears.” Rawes says that visiting the hygienist for a scale and polish, and whitening the teeth using custom-made at-home trays are the fastest, lowest-effort ways to upgrade your smile. Expect to pay about £375 for whitening.

Still operating on the presumption that a pressed outfit signals that you have your shi(r)t together? Keep up. “Youth culture treats ironing like a hobby from the 50s, which means creased natural fabrics have become the ultimate modern Prada-esque symbol of chicness,” says the Guardian’s fashion and lifestyle editor, Morwenna Ferrier. “Looking kempt means looking corporate.” Also: “Don’t tuck things in. Modern fashion is all about the drape.”

“Why are so many men of a certain age walking around wearing hideous chinos, which sag at the knee and taper at the ankle?” bemoans fashion consultant Simon Chilvers.
