Activated Charcoal and Charcoal in Skincare: Does It Work to Purify Your Skin?

Recently I've been seeing lots of charcoal-based skincare products around, along with claims that would make anyone sit up. The main argument is that applying charcoal to your skin will help to purify your skin. Thus, marketers tend to stress charcoal as pore-clearing, acne-reducing, skin-detoxing wonders. There are so many products out there, all with the same marketing talking points. Some products even stress that they have activated charcoal, no less (all it really means is that the charcoal is more porous and thus allowing a larger surface area for adsorption, but by and large its chemical properties will be the same). Just take a look at the graphic I've helped you guys put together, and you'll know what I mean:


Lookit all those charcoal-laden products! If such products work, why don't we all have awesomely detoxed skins?

So there is a lot of charcoal-laden skincare out there. But is there any truth to all the claims these products make? That's a question that's worth answering.

Charcoal first got its reputation for being "cleansing" due to its ability to adsorp a range of unsavory by-products and poisons, including chlorine, odors, and pigments (although there are some exceptions, such as iron, lithium, potassium, and ethanol). This makes it useful particularly for certain functions, such as surface water (like rivers) and treating drinking water (e.g. all those Brita water filters). It also seems to have some help with treating poisoning when taken orally, although as you might expect its effectiveness is also partly influenced by time and dosage, so it doesn't work all the time. So that's our primer on charcoal and activated charcoal: great for purifying water, and might help with poisoning when taken orally.

So it's easy to see how charcoal got its reputation for being able to purify things. And from there, it's also easy to see how from there, some creative product manager in a company thought, "Hey, if people believe that charcoal helps to purify their water and their innards, then they should believe that it purifies their skin, too! Mmm, charcoal face scrubs and cleansers...Mmm...MONEY! Let's do this, baby!" But of course, purifying the water in a plant and adsorbing to impurities when taken orally are pretty different. So rather than just jumping to conclusions (charcoal in body works = charcoal on face works), we really have to go back to review the literature available, and see what it says about charcoal applied to the skin.


Things that charcoal CAN do: clean your water. Things that charcoal CAN'T do: clean your skin. (Source)

And so, what does the scientific literature say? Well, sadly, when I delved through the scientific literature (PubMed is absolutely my BFF for things like this), I couldn't find anything at all demonstrating that charcoal, or activated charcoal for that matter, led to an improvement in skin quality when applied topically, especially in the cosmetic kind of way we are looking for. The closest studies I could find dealing with charcoal and skin looked at the effectiveness of using activated charcoal dressing to reduce smell in wounds. There is also some evidence that when applied topically it treats porphyrias, but basically, all of the demonstrated effective skin-related uses for charcoal are basically either involving ingesting the charcoal, or else applying it directly to wounds. Beyond such medical uses, there isn't any proof that it will work to effect cosmetic changes when applied topically to uninjured skin, which is what you are looking for ion a skincare product.

And now I think you know what my conclusion will be even before I type it out, but first, let's give you a friendly nice infographic, courtesy of yours truly fooling around on the computer:


Be a smart shopper: Most charcoal-containing products rely on other workhorse ingredients to clean your skin.

But just in case that infographic didn't make sense to you: what does this mean for us, consumers told to buy this or that charcoal mask? Well, what it means is that, there is no literature to say that it will do anything for your skin. The most concrete use of charcoal in skincare products that I can think of is that including black charcoal beads in scrubs will be a pretty cool-looking exfoliator. But it definitely won't "detox" or "purify" your skin or whatever grandiose terms the marketers are putting out there (in anycase, I find the concept of "detoxing" an organ like your skin more of a marketing concept than a scientifically useful one). For what it's worth, most products that advertise their charcoal product as being "purifying" or cleansing, tend to include other ingredients that are responsible for the cleaning effect, e.g. salicylic acid to dissolve the oil in your pores, kaolin clay or talc to absorb oil, and so on. So it's not that a product advertising charcoal won't work. It might, but if it does, you can bet that it will be these other workhorse ingredients that do the job, not the charcoal. The inclusion of charcoal just sounds sexier from a marketing perspective.

So if a product advertised with charcoal is something you like - say, maybe you like the packaging, brand, or even colour, go ahead and buy it. But just don't put your hard-earned money into a product because you expect the charcoal to do magic on your skin, because there is no proof that it will do anything. More than likely, it will be the other ingredients that do the job, not the charcoal, and as a savvy shopper, you'll probably want to look at the formulation in its entirety, rather than just hinge your buying decision on a single marketing ingredient.

  1. what an interesting post, it just goes to show how easily us consumers are fooled into thinking an ingredient is going to work miracles when there's no research behind it whatsoever. Everyone should have a read of this before they part with their hard earned cash! x

  3. I was just thinking about this a few days ago! I saw a mask containing charcoal and thought, why would this help the skin. Ok, maybe as a peel as abrasive, but in mask? But you can't really say for sure without going through pubmed and often at least a few articles and I got lazy :/ Thank you for looking into this :)

  4. My bf just tried eating charcoal ramen yesterday and the menu totally blabbed on about how detoxifying it is lol. Thanks for this post, there's so many myths out there in beauty products that it's hard to distinguish fact from fiction.

  5. @MissJ: I can't imagine what charcoal ramen looks/tastes like! Care to enlighten me? :) And actually, there is more evidence for eating charcoal (to help with some types of poisoning) than there is for putting it on your skin, although I'm pretty sure the charcoal ramen was also another gimmick. I hope it tasted good though!

  7. Thanks for writing this informative blog post. I'll be honest, I was completely fooled by all of this marketing. I was planning to save my money and splurge on some charcoal-based skincare item but not anymore!

  8. While I appreciate the thoughts expressed, the reality is that some of these products actually work. The Origins product, for example, has completely eradicated all of the blackheads on my nose which is shocking since I've had numerous blackheads on my nose since I was 12 (I'm 33 now), and have never before found a product that eliminates them much at all. The absence of scientific literature does not mean that something doesn't work, it may simply mean that it has not been thoroughly researched if researched at all. Perhaps some scientific research is in order. Have you tried a charcoal mask on your own pores?

  11. I work in a power plant that uses charcoal for flue gas abatement. Occasionally I get it on my skin and it really really really dries me out. Its horrible. I also have one of those charcoal and gelatine rip out your blackheads mask type thingies. It doesn't work but it does rip off the top layer of skin which probably does some good.

  12. well I don't have acne but I have use activated charcoal straight without mixing with other chemicals and I find it does wonders. I had a bad took infection and I applied activated charcoal in water and made a poultice to my face for days and got rid of infection and my daughter came over and said what did you do to your face. One side looks dry and rough and the other looks so soft and smooth. I asked which side of my face looks soft and smooth and she picked the one I had been using charcoal on. She had no idea I was using anything on my face and she saw a big difference. The other side she said looked dry and rough is dry because I have major dry skin. But the charcoal side looked so soft and smooth.
