We knew you're gonna ask this.Many brands sell bars claiming them to be soap-free soaps, but they're not actually true soap.Soap-free soaps are usually made with synthetic surfactants, that more often than not are petroleum-based and non-biodegradable.Not only surfactants are made from the double processing of fossil fuels, they tend to strip the skin from its oils, interfering with your body's microbiome and your skin's natural protective barrier.
