Activated charcoal can be taken either systemically or applied topically for local benefits.
Usually activated charcoal is used in treating poisoning. Apart from this, it has cosmetic benefits, especially in dermatology as skin lightening agent.
Nowadays concern has been given in using this as teeth whitening agent.
