If you’ve browsed health or beauty products at any point over the last couple of years, you’ll be familiar with activated charcoal. Once almost completely unknown in the UK, activated charcoal seems to be everywhere from our toothpaste to our water bottles.
What is this stuff – and why is it suddenly everywhere? And most importantly – should you be using it?
Strange though it may seem, the stuff that ends up in smoothies, face creams and toothpastes shares many of the same organic materials as BBQ charcoal – it’s just been through a few extra steps.Activated charcoal powder, also known as activated carbon powder, is made by finely grinding charcoal. This is then ‘activated’ by exposing it to oxygen and heat-treating it at extremely high temperatures.3 During this activation process, the carbon atoms in the charcoal are rearranged and the charcoal gains thousands of tiny holes in its surface, like the pores of our skin. These pores give activated charcoal an almost unbelievable amount of surface area – 1ml of the stuff has around 1000sqm exposed surface.4
These pores are very absorbent, hence activated charcoal’s reputation as a toxin sponge.
But why has it found its way into our beauty products?
Today, though, you’re likely to see activated charcoal on bathroom shelves and in kitchen cupboards across the UK.As you will no doubt have noticed, the detox trend has been going strong for a while now. Back in 2014, Harper’s Bazaar called activated charcoal the ‘detox du jour’ and told of an emerging wellness trend in Los Angeles of consuming activated charcoal tablets and adding it to juices.6
You can buy activated charcoal at most health food shops and in chemists and shops selling wellness products.The global activated carbon market size was estimated to be worth almost $5 in 2018 – and is expected to expand at an annual growth rate of 17.5% by 2025.7
Alternatively, you could make your own with a teaspoon of activated charcoal powder mixed with coconut oil. Try to make it with chilled coconut oil from the fridge, as if it’s room temperature it gets too runny.
A word of warning – as activated charcoal is so good at absorbing things, take care if you’re on medication as there is a possibility it might be less effective while taking charcoal by mouth. It’s always best to check with your GP first.
