Strengthens Skin and Hair! RA Cosmetics 100% Raw Black Soap Body Wash (Unscented) is generally made with plantain skins, a good source of Vitamins A and E as well as iron. Vitamin E is an antioxidant that helps your skin retain its health and moisture. Vitamin A keeps your skin young and fights wrinkles and spots. Iron may also strengthen your skin and hair. Provides UV Protection Many types of black soap are made with large amounts of shea butter. A study published in the "Journal of Photochemistry and Photobiology" found that the caffeic acid in shea butter fights UV radiation. Using raw black soap may help protect your skin from sun damage. However, be sure to use other forms of protection as well. Alleviates Acne Black soap has traditionally been used in Ghana and Nigeria to treat acne, oily skin and blemishes. This may be a result of the potash that gives the soap its black color. However, because potash can be made from a variety of trees, you may need to try various black soaps to find the one with the greatest acne fighting effect. Reduces Skin Irritation Raw black soap is often used in shaving, to help fight eczema and psoriasis. As with acne, different varieties of black soap may have varying effects on skin impurities. However, the shea butter in the soap helps to moisturize and smooth skin, alleviating itching and other irritations.
