Activated charcoal soap is made by processing a high-carbon material at a high temperature and then “activating” it with hot air or steam. Its large surface area allows it to absorb toxins, which is why activated charcoal in soap theoretically binds to dirt and oil on the skin and helps clear out pores. Charcoal seaweed is made with charcoal, ground seaweed, pink salt, rich oils and butters. Lathers beautifully and has a great spa scent.
