Follow the advice of Dr Stefanie Williams of Eudelo Skin Clinic and invest in your skin as a starting point for feeling your most radiant this summer. Her recommendation is a hardworking peel, which will target pigmentation and is safe and effective for all skin tones.

Meanwhile those with lighter and more mature skin could benefit from an IPL or ablative laser. Dr Jenny Doyle of The Clinic Holland Park is a fan of BBL laser and Halo. “And get it done asap,” Doyle says. “You want to plan a period of downtime and also have it done as far away from sunny periods as possible.”

Treatments aside, there’s also plenty you can achieve with high-quality skincare at home. But note: if you’re a rookie, don’t start on retinols and high-strength vitamin Cs right now, Williams says. Instead, look out for polyhydroxy acids. “You get a nice brightening of the skin, a reduction of dullness and refining of the surface, without going through that flaky stage.” She also recommends introducing three supplements to your daily routine: “a liposomal glutathione to support brightening, an oral antioxidant to help with evening out and a hyaluronic acid for internal hydration.”

Fallen off your fitness journey since January? Master trainer Dr Lucie Cowan of luxury London fitness club Third Space suggests implementing a varied, well-structured workout plan that combines strength training, cardio and mobility. And, as long as you’re consistent, “you can expect to see changes in muscle definition, fat loss and overall body composition,” she says.

For added tempo, schedule yourself in for a course of Hiit classes. “The best thing about exercise is you can feel results immediately, if you flip the switch from looking just for physical change and start prioritising mental rewards,” says Barry’s UK cofounder Sandy Macaskill.

If you’re looking at dietary changes, avoid cutting calories, Cowan says. Instead, focus on eating nutrient-dense foods and upping your protein intake – especially at breakfast. And if there’s one resolution she recommends adding to your pre-summer to-do list, make it getting a good night’s sleep.

Perhaps you’re the sort of guy who’s been diligent with your skincare and is simply looking to maximise your results. If that’s the case, then Moxi laser is your best bet (and it’s safe for all skin tones). Doyle is the first to sing its praises. “It’s a very gentle non-ablative fractional laser, it’s low downtime and within five days your skin looks radiant,” she says. Expect a noticeable improvement in evenness after one session – although if you can squeeze in a couple before summer, then it’s certainly worth the course.

Alternatively, if you’re looking for all-round improvements in texture and tone, consider a round of microneedling. This uses a sterilised tool with dozens of microscopic needles to create tiny wounds, which then heal to reveal fresh skin.

Depending on how comfortable you are with needles, week four would be the best time to supercharge your complexion with skin boosters. Dr Marco Nicoloso of London- and Dubai-based superclinic Ouronyx recommends Profhilo, which uses hyaluronic acid molecules deeply hydrate of the tissue and give you that juicy, just-stepped-off-a-yacht skin. Meanwhile, Doyle is a fan of polynucleotide treatment Ameela, which stimulates the muscle cells and is brilliant for helping reduce stubborn under-eye bags.

Likewise, mesotherapy, which involves a series of micro-injections of vitamins, antioxidants and lots of other good stuff into the epidermis, will soup up your skin faster than any serum. Dr Ivy Igerc of 111 Harley St suggests booking yourself in for a couple courses, spaced two weeks apart, for a guaranteed A-list-actor glow.

Most personal trainers will hammer home the importance of “progressive overload”. Which is to say, if you’ve got a firm handle on your workout routine by week five, then it’s time to up the ante. “Increase the intensity of your strength training workouts by either increasing the weight lifted, the number of sets and reps or reducing rest time,” Cowan says. “Continue with the same workout split as the earlier weeks, but aim to push yourself a bit harder.”

And don’t leave your warm-weather wardrobe to the last minute. For pointers, here’s our guides to finding the perfect T-shirt, the right sunglasses and whether you can wear shorts to work (that depends on where you work).

Time to treat yourself to a facial – although not exactly the calming kind. High-performance treatments to look out for include the HydraFacial, which deep cleans and hydrates the skin, or a gentle acid peel to brighten. Clearlift, a lunchtime-friendly laser, will also help target pigmentation and texture while boosting collagen in the dermis long term. “It’s especially great to do right before the start of summer as you achieve instantaneous results,” says senior aesthetician Rachael Myers of 111 Harley St.
