People have been using activated charcoal for thousands of years. Activated charcoal pulls out toxins and other impurities from your skin to leave it extra-clean. A 2019 study found that an activated charcoal mask was able to enlarge the pores and effectively cleanse the skin by removing dead cells. Activated charcoal not only absorbs toxins but it is also antibacterial and anti-inflammatory, which means it can help with acne as well.
