The addition of activated charcoal makes these Earthen Myrra soap bars highly beneficial for the skin. This special line of bars is for those who want unscented soaps. At Earthen Myrra, we follow a traditional soap making technique call the Cold Process Method. It takes 4 weeks to cure. Usually all the soaps are made in small batches on regular basis to maintain the stock. Shelf Life: 8 Months( its safe to use even after 8 months but since these are natural soap bars and are all scented with essential oils only, the fragrance fades away)
