Adam Friedman, MD, FAAD, professor, interim chair, and director of the George Washington University Dermatology Residency Program gives his expert opinion on the evidence, or the lack thereof of activated charcoal in dermatology. Activated charcoal is a trend that many swear by for teeth whitening, hangovers, detoxification, acne, and much more. The unique structural properties of activated charcoal make it quite useful in treating acute poison ingestion, however the evidence is lacking for many other claims, as Dr. Friedman discusses.
