Alkaline shea butter soap At ZARTGEFÜHL, we have developed the creamy white soap specialty especially for skin prone to neurodermatitis. This 100% natural soap is not only unique in its appearance, but also perfect for facial cleansing and even bathing. With a pH value of at least 8, it is a pure alkaline facial soap that has the ability to neutralize the harmful acids that the skin secretes as the largest organ in humans. Unique and incomparable! Why is ZARTGEFÜHL facial soap so extraordinary? ZARTGEFÜHL soaps are not common soaps that you can buy anywhere in a shop.
