Turns Out Your Charcoal Skincare Products Might Not Be Doing All They Claim

Some ingredients are so beloved in the beauty community that we often forget (or maybe just look past the fact) that little evidence exists to support the claims. Take charcoal, for instance. Never mind the trendy drinks and toothpaste; the list of charcoal-based products in the skincare department alone is overwhelming enough. The natural ingredient has long been used in medicine to remove toxins in the body,1but the idea that charcoal can do the same for your skin isnt backed up by research—just countless theories and testimonials, and convincing ones at that. So what do we do with all those charcoal masks weve all stockpiled? Its a confusing spot to be in, so we enlisted the help of skincare experts to fill us in on the facts about using charcoal for skin benefits.

Keep reading for some expert insight on charcoal for skin.

What is Charcoal?

Charcoal is the result of burning carbon-based materials, which makes sense if youve ever come in contact with the chalky, sooty substance. Although you might hear the terms "charcoal" and "activated charcoal" used interchangeably in the beauty industry, Wong says activated charcoal has been treated to produce a much larger surface area for adsorption. As she explains it, when charcoal is treated with gases or inorganic chemicals, its forced to open up and form pores (think of a microscopic sponge).

Not to get too technical, but activated charcoal works by using dispersion forces, which is a type of intermolecular force. "Dispersion forces are sticky forces that act between all substances microscopically," Wong explains. "They form due to temporary dipoles formed from the movement of electrons. Because activated charcoal has a large surface area, it has a lot of space to form dispersion forces with other substances." Its this sticky characteristic that makes activated charcoal effective at removing substances when it comes in contact with them and why its earned a reputation for being such a good detoxifier. "In medicine, we have used activated charcoal to remove toxins to treat medical conditions such as poisonings, gastrointestinal tract infections, and nausea," Levin says.

Activated charcoal is often found in masks, face soaps, exfoliating sponges, deodorant, and hair and scalp treatments, but its also available on its own in the form of loose powder or tablets.

Benefits of Charcoal for Skin

Charcoal has a number of benefits for use on the skin according to manufacturer claims. However, there are few studies that can be used to back these claims which means the benefits, for the most part, are anecdotal. Heres a closer look at the benefits of using charcoal on your skin, from reducing the appearance of pores to ridding your skin of impurities.

Rids skin of impurities: Using charcoal on your skin may help with cleansing dirt and dead skin from the surface. A 2019 study concluded an activated charcoal peel was capable of "cleansing the skin by removing dead skin on the skins surface. However, a 2021 study found activated charcoal to exhibit no clinical data that proved its ability to rid the skin of impurities.Shrinks appearance of pores: The previously mentioned 2019 study also found pores were enlarged during the process of using activated charcoal. This allowed for deeper cleansing which may help unclog pores leading to your pores appearing smaller. Keep in mind, even though charcoal may help with the appearance of pore size, it cannot actually shrink pores. Pores size is determined by your genetics and cannot be permanently changed.Helps with exfoliation: The gritty texture of charcoal makes it an effective and natural exfoliant. It will also soak up oil present due to its absorbent qualities. Using charcoal on your face can remove debris and dead skin cells built up on your skin to reveal your smooth, fresh skin underneath.Deeply cleanses and fights acne:

Theoretically, the "stickiness" of charcoal works to treat acne and detoxify the skin by removing dirt and oil, but Wong says these claims lack the science and research needed to back them up. According to Levin, its unclear whether its ability to remove toxins can be translated to removing them from the skin through topical application. "Many of the charcoal cleansers or masks are promoted to be useful for acne-prone skin," Levin explains. "However, these charcoal cleansers or masks are coupled with known acne-fighting ingredients, such as alpha-hydroxy acids, and beta-hydroxy acids, like salicylic acid, which is a lipophilic (oil-loving) ingredient used to remove sebum from pores, kaolin, which is known to bind sebum (oil), and/or fruit extracts." Therefore, Levin says it may be too early to say that charcoal itself is an effective treatment rather than the additional ingredients that have already been established to have efficacy on skin exfoliation and sebum control.

Side Effects of Charcoal

In general, Levin says charcoal is inert and does not cause allergic or irritating reactions, and will likely do no harm, but its also important to take into consideration the product youre using and the other ingredients included in the formula. In other words, all bets are off for that one viral (and potentially damaging) charcoal peel-off mask that was all over your social feeds and any other ones like it. Instead, opt for a gentle charcoal-based product to protect the skins barrier.

How to Use It

Activated charcoal relies on physical contact to remove toxins, so in theory, it would be most effective at removing oil when applied for a prolonged period before being removed. However, because there is so little data on the benefits of charcoal for skin, Wong says theres no information available on how or how often you should use it. If you choose to try a charcoal-based product, the best advice is to follow the manufacturers instructions.

Other Forms

As we mentioned before, charcoal can be applied topically in an attempt to treat the skin or taken orally for medical purposes. The topic of ingestible charcoal for at-home detoxification is controversial and highly debated (always consult your physician before adding any supplements into your regimen), but when speaking about charcoal as a skincare treatment, specifically, the ingredient should not be consumed orally. "I do not recommend ingesting charcoal for acne treatment purposes," Levin says.
