Handmade Cold Process Grapefruit and Rose Kaolin Clay Vegan Soap Awaken your spirit! Like the essential oils of most citrus fruits, grapefruit essential oil has an uplifting and relaxing effect on the mind. Bringing out positive feelings of hope, it is believed to relieve anxiety and stress. Rose kaolin clay (also known as pink clay), is a mild clay for normal to dry skin and will help to gently cleanse and exfoliate the skin. Fern & Nettle soaps are handmade using the cold process method in small batches. Bars will weigh between 4-5 oz. Due to the nature of the soap, all bars are different and unique. Products are made by hand using natural ingredients.
