Unknown Benefits of Activated Charcoal for Skincare
Activated charcoal, known for its adsorbent properties in the emergency room, has also found its way into skincare products. But, what does the science say about its effectiveness in treating blemishes, dry or oily skin, or acne?
The porous nature of activated charcoal allows it to adhere to and absorb dirt, oils, and impurities on the skin, theoretically deep cleansing pores and reducing excess sebum. Charcoal soaps, including those with activated bamboo charcoal, are marketed to draw out impurities and exfoliate the skin gently, potentially helping with acne and maintaining clearer skin.
However, rigorous clinical studies confirming these claims are largely lacking. While there is some evidence suggesting activated charcoal may help remove impurities and unclog pores, the scientific evidence supporting its use as a skincare ingredient for treating blemishes, dry or oily skin, or acne is limited and mainly anecdotal.
A 2019 study suggested that an activated charcoal peel-off mask could enlarge pores and enhance skin cleansing by removing dead cells. Another study in 2021 found that a 25% activated charcoal product could brighten dry skin on the hands without causing irritation.
Despite these proposed benefits, it's important to note that there is little high-quality scientific evidence demonstrating strong efficacy of activated charcoal in topical skincare products for acne, dry skin, oily skin, or blemishes.
Activated charcoal products may help clear blackheads and improve the appearance of acne or spots on the skin, but this is mostly supported by preliminary or indirect evidence rather than definitive clinical trials. Some reports mention potential risks such as skin irritation or allergic reactions, indicating charcoal products may not be suitable for everyone.
When it comes to exfoliation and aging support, there is no evidence to suggest activated charcoal provides these benefits. However, a 2019 research review suggests that it is generally safe for topical use. Still, using activated charcoal products may cause irritation in some individuals, and it is important to discontinue use if a rash occurs.
Activated charcoal has been used medicinally since ancient times, including by the Egyptians to eliminate bad smell from infected wounds. Today, it is also an ingredient in skin and dental care products. One teaspoon of activated charcoal has an absorptive surface area equivalent to a football field, making it very effective at adsorbing substances.
However, it's crucial to remember that activated charcoal should not be taken internally unless directed by a doctor, as it can cause side effects such as vomiting and pulmonary aspiration.
In summary, while activated charcoal's absorptive properties provide a plausible mechanistic basis for its use in skincare, firm scientific proof validating its effectiveness for treating blemishes, dry or oily skin, or acne is currently insufficient. Users may find it helpful anecdotally or as part of cleansing routines, but should be cautious of potential irritation and not expect it to replace clinically proven treatments.
