To turn your walk into a workout, try adding in short bursts of speed – up to 30 seconds or a minute of faster walking. According to Greg Whyte, Professor of Applied Sport and Exercise Science at Liverpool John Moores University, you'll naturally get faster as you get aerobically fitter.  

From celebrity make-up artist Nick Barose: 'One of the best tips I learned is to mix liquid foundation with waterproof sunblock to make it stay in the heat.' His melt-proof ratio is one part waterproof SPF with three parts foundation.  

If you're trying to lose weight, avoid low-fat products. When manufacturers take the fat out of food, they tend to replace it with sugar. Fat is only a problem in diets when carbohydrate levels are high.  

Wash off dirt and make-up with a mild cleanser before a sweaty workout. Any make-up or debris left on skin during exercise becomes a pore-clogging film, potentially leading to breakouts.  

Reading this on holiday and having trouble sleeping in the Lucifer heat? In extreme heat, keep a damp flannel by your bed and mop your brow as you would for a child with a fever. Meanwhile Sammy Margo, author of The Good Sleep Guide, recommends that if you do have a fan, it's not pointing at you – this can lead to a crick in the neck.  

Here's a new 'pulse-point' we've been trying recently: the palms of the hands. The warmth encourages fragrance to expand so you can enjoy fragrance everywhere you touch.  

Nail polish needs a grease-free surface to cling to – but swiping nails with remover before varnishing can be drying. Instead, try using witch hazel.  

Having trouble sleeping when the nights are hot? Try a silk or linen pillowcase as these tend to keep your head cooler.  

To make your eyebrow arch look higher, highlight right above the arch, in addition to below.  

With the boom in home visits by beauty professionals, it pays to be prepared. Hair should be freshly-cleaned and damp if you're expecting a hairstylist, while if you're having your make-up done, your face should be cleansed and moisturised.  

Remember to apply neck cream to the back of the neck as well as the front, and the small area under the chin – this is where excess slackening causes 'turkey neck'.  

We love this wisdom from yoga teacher Jane Kersel, who believes: your best body is not one that looks incredible, but one that you're at ease with. 'It's not rocket science: stop obsessing. If you don't move, your body will lose its tone, it will seize up and you will end up looking like the shape of your chair.'  

From Laura Mercier: 'Apply as little foundation as possible, and don't be afraid to massage it in with your fingers. Many women make the mistake of painting on top of the skin, rather than blending it properly. Don't feel you need to cover your whole face, either – just focus on the areas where the skin has more redness than you would like. Foundation is designed to even out skintone, rather than cover blemishes.'  

To avoid cosmetics bottles leaking when you fly, make sure bottles aren’t filled to the brim (they’ll expand under pressure in a plane). To create a vacuum seal, remove the cap, squeeze the bottle so that the liquid inside bubbles to the top, then screw the top on while holding the squeeze. For absolute safety then wrap containers in Ziploc-style plastic bags (with a closure at the top) – then in a worst case scenario, if they do spill, the mess won’t damage the clothes in your suitcase.  

We like to fly bare-faced (or remove make-up when we’re on board a plane), so that we can regularly slather on plenty of moisturiser at 37,000 feet. But nevertheless, go for cream-based products, because skin wil be dryer than usual.  

If you’re trying to bounce back from overzealous tweezing, book in for an eyebrow tint, which darkens even the lightest hair.  

To take the redness out of a spot, dip a Q-Tip in eye drops and place in the freezer for 30 minutes. Then hold it gently on the blemish for a minute to take down the inflammation and swelling, and then fan the area dry.  

Don’t be tempted to leave it too long between trims. As our friend Charles Worthington observes: ‘Invest in a good haircut and your styling time will be cut in half.’  

Hot feet? Give your feet a massage every night before bedtime with cooling coconut oil.  

Never layer active products like retinol and AHAs such as glycolic acid – it’s a recipe for a reaction, because they both have an exfoliating action and can lead to soreness and excessive peeling.
