I recently started making a facial bar with activated charcoal because customers with acne were requesting it. One of my very best customers bought a bar last month and has been using it since. She did not have acne before but since using the activated charcoal bar has several spots of tiny pimples on her face. The base oils / butters and essential oils are the same as my other bars that she uses and loves. Activated charcoal is the only difference. Do you think the charcoal is drawing out impurities or maybe is too harsh for her face?
