Every year we're inundated with a slew of new beauty trends promising to revolutionise the way we look and feel, told time and again we need to step back and detox from the whirlwind that is everyday life. But with so many methods to try, how can we know where to start (and whether pricey products are worth investing in)?
We put five of the latest and greatest skin detox trends on your radar, from 5:2 makeup 'diets' to detoxifying baths, to help you get started.
The 5:2 skin diet
What is it? You might have tried the 5:2 diet, where two days of the week are spent fasting, the remaining five, eating whatever you fancy (up to a point). The 5:2 skin diet adopts the same routine, but applied to makeup - the idea being that a two-day breather will allow your skin to exfoliate itself more efficiently.
What do you do? Two days of the week are spent au naturel, the rest wearing makeup as you would normally.
Does it work? Similar to how scoffing greasy food for five days after two days of fasting won't help you become healthier overall, applying thick, abrasive products to your skin for the majority of the week won't be solved by two days off. Use makeup that works in harmony with your skin, match products to your skin type and always remove makeup at night with a decent cleanser. Allowing your skin to breathe for two days is helpful, but using less makeup overall will have a lasting effect.
What is it? Taking a holistic approach to detoxing, detox baths are said to draw toxins from your body as you soak - not to mention relieve stress, which also helps with skin renewal.
What do you do? Add Epsom salts, bentonite clay, baking soda, essential oils or apple cider vinegar to your bath.
Does it work? Skin specialists like Liz Earle and Dalton Wong, Jennifer Lawrence's personal trainer, swear by the detoxifying effects of detox baths - so we'd be inclined to say they do. At the very least, you can do worse than treating yourself to a soothing bath when feeling burnt out.

What is it? Said to boost circulation and flush out toxins, it's exactly what it sounds like - sweeping a dry brush over the body to aid the lymphatic system to drain.
What do you do? Always motioning towards your body, sweep a soft-bristle brush across the skin for a few minutes every day. Follow up by drinking plenty of water.
Does it work? It definitely clears away dead skin cells, but the skin does this naturally up to the age of about 30 - and brushing too hard can be harmful to skin too. Elle Macpherson is a huge advocate, but there's not much research to back up the claims. Dr. Tina Alster, director of the Washington Institute of Dermatologic Laser Surgery, told Time magazine, "the actual benefits are unclear".
Brushes to try: Bath brush, £12, available at The White Company
What is it? Absorbs oil and debris from the skin like a magnet with its super-porous surface, helping to cleanse the skin of impurities.
What do you do? You can find the fine black powder in everything from detox cleanses (in the form of pills and juices) to soaps and face masks by Origins and Biore.
Does it work? Actress and holistic therapist Shiva Rose is a huge fan, using it to treat bug bites and as a teeth whitener.
Products to try: Origins Active Charcoal body wash, £18, available at Selfridges.com
What is it? The practice of massaging facial muscles to increase blood circulation and brighten the skin by draining toxins.
What do you do? When moisturising, rub a small amount of product between your fingers and really concentrate on working it into the skin using small, circular motions. Start at the base of your face, working up to the nose then across the the temples. Go carefully around the eyes, working from the outside in to drain fluid.
Does it work? Beauty insiders and therapists swear by massage - there's a reason your skin looks so fabulous after a facial.
