The addition of cocoa butter, squalane, and argan oil boosts the moisturizing effects of this soap for smoother, silkier skin. The Fermentation Facial Soap line brings to bear the holistic power of fermentation through three distinct varieties: Natural, Rich, and Premium. Each soap is made with organic rice lees born of a natural, yeast-based fermentation process that yields high levels of skin-supporting nutrients, such as vitamin E, arbutin ferulic acid, and a variety of healthful amino acids. The result is an all-natural soap loaded with easily absorbed nourishment and hydrating oils that tighten and lighten skin by reducing blemishes, soothing inflammation, and delivering moisture where it's needed most. Fermentation soaps are also petroleum-free and unscented, save for the sweet and subtle aroma of rice.
