If you aren’t taking seriously the threat of blue light in terms of skin ageing, listen to Dr. Howard Murad. ‘We are at the early stages of understanding the long-term impacts of blue light on skin, but our initial estimate is that four days in front of a computer exposes the skin to a total irradiation as intense as 20 minutes in the midday sun.’ So: wear your sunscreen and power up the antioxidant protection, at your desk…

Might a little crystal healing prove helpful at the moment? Crystal enthusiasts believe that these powerful stones work on an energetic level to bring about vibrational healing, via stones placed around the house and on the body. Try amethyst to help you relax, lapis lazuli for peaceful thoughts and hematite or moonstone for deep calm.

It might be tempting to skimp on cleansing in the morning – but either wash with a facial wash, swipe with a flannel or use an AHA- or toner-infused pad, to sweep over skin thoroughly. Oils and dead skin cells build up while you sleep and your daily skincare will be absorbed better by clean skin.

If you’re finding it hard to motivate yourself to exercise, lay out your exercise clothes the night before. It makes it harder to goof off when you’re lying in bed looking for excuses. (Even 10 minutes of walking is better than nothing.)

How do you choose specs to suit your face? As a rule, square or wide frames suit round faces; longer faces need bigger frames with a deep bridge; square faces look best in round frames or a top-heavy style, and heart-shaped faces can pull off almost any shape. Basically, avoid matching the shape of your frames to your face shape. (As trying on glasses in store has been challenging since the start of the pandemic, we’re rather loving Specsavers virtual try-on, on their website.)

There is only one style of comb that should ever be used on thick hair: a wide-toothed plastic comb. Pay a little more for something that’s smooth, and always de-tangle from the tips, working up to the scalp.

If you're someone who meditates but you know you have a tricky week ahead – a packed schedule, travelling for work and/or staying in a hotel with noisy neighbours – pre-plan for failure. Happiness expert Gretchen Rubin recmmends that you anticipate as many challenges as you can and specifically think about what you'll do and say to overcome them. (For instance, a walking meditation in a nearby park, rather than trying to zone out the person in the neighbouring hotel room who's got breakfast TV on too loud...)

For a soothing soak, try Himalayan salts, which contain the same trace minerals as the body. 'As you bathe, they enter the body to replace lost minerals and diminish toxins,' says Anita Kaushal, co-founder of Mauli Rituals. She recommends adding to a warm bath and bathing for 20 minutes once a week. If dry, itchy or irritated skin is your problem, meanwhile, try Dead Sea salts, said to improve skin's barrier function and also improve its texture.

If you're a fan of body brushing, switch to a more delicate, softer facial brush for the décolletage and neck. Just 10 seconds of gentle, northward strokes will rid the neck of any dry, flaky skin.

Feeling stressed? Tidying your desk may really help. Research by Catherine Roster at the University of New Mexico identified a vicious circle in which stress and high work demands increase indecisiveness and our propensity to accumulate work-related clutter. This clutter reminds us of tasks left undone, increasing stress levels still further. Spending five minutes creating some order around our keyboard and screen may be repaid many times over may well make us more productive.

Not yet a convert to double cleansing? Facialist Nichola Joss starts by taking her make-up off the minute she walks through the door. 'I start the first part of my cleansing ritual as soon as I get home,' she explains. 'The first cleanse removes make-up, grime and pollution; the second cleanses the pores and nourishes. I then put on my army of defence – retinol serums, for instance – so they have time to absorb and start doing their work. At bedtime I massage in a facial oil, which relaxes the muscle tissue, nourishes the upper layers of skin, traps the retinol I've applied earlier and reactivates it. And this eases me into a good night's sleep...'

If you tend to oversleep, keep a spray bottle in the bathroom for emergencies. Spritz your hair, add a little mousse, turn your head upside down and blast with a blow-drier, or scrunch into shape.

We love this wisdom from yoga teacher Jane Kersel, as an alternative to stressing about a body that’s less than ‘perfect.’ (In our book, there’s no such thing.) ‘Start to enjoy your body. Get out of your head and start to see your body as the sensuous playground it is. Focus on the feel of how it moves, what it’s like to breathe, the pleasure of stretching. Learn to marvel at the engineering of your hand, your foot, your arm and your hips. You want to begin to treat your body like your best friend, not the enemy. The more you do this the more you will enjoy moving your body; it will start to feel like something you have to do every day.’

If foundation makes your pores look big, try switching to powder foundation – it’s better at staying where you put it, and won’t settle into pores and creases.

Feeling down? Try adding turmeric to your diet. In Ayurvedic medicine, it’s relied on to raise energy levels in people suffering from depression or lethargy. (We LOVE a turmeric latte – now very widely available in coffee shops.)

When drying skin after you’ve washed your face, never rub: simply blot the face with a soft, clean towel to avoid skin appearing blotchy.

A quick clue as to how long a lip gloss will last, according to Linda Wells (author of Allure: Confessions of a Beauty Editor, and now to be found at the brilliant Airmail.com): ‘Pick the right gloss by looking for a few code words. Names that sound hard or thick (‘lip lacquer’, ‘glass’, ‘diamond’) will likely have more colour, be nearly opaque and stay put longer; wet words like ‘juicy’ or ‘slick’ are signs of sheer, ephemeral colours.

Remember with fake tan: two applications of lighter colour always look more natural than one application of dark. Always opt for Light/Medium rather than Medium/Dark, if you want a seamless finish.

If your bathroom cupboard’s cluttered and products are hidden at the back making it hard to reach them, invest in a ‘Lazy Susan’ – one of those circular storage solutions you’ll find online at stores like Lakeland. The ‘turntable’ means you can access everything easily.

Feeling sluggish after the Bank Holiday? Massaging your ears can increase energy, creating a sense of wakefulness,’ advises Mary Dalgleish, former vice president of the Federation of Holistic Therapists. ‘Simply rub the edges of your ears between two fingers, from top to bottom a few times.’
