What is the difference between the Glutathione Soap, Papaya Kojic Soap, Black Soap and the Licorice Beauty Bar?
Keep in mind that results do vary from user to user. But generally speaking, of the four products, most users will find that the Diana Stalder Glutathione Soap is most effective at overall whitening, followed closely by the Diana Stalder Papaya Kojic Soap, Black Soap then the Diana Stalder Licorice Beauty Bar. The Diana Stalder Papaya Kojic Soap has a micro-exfoliation (micro-peeling) effect, and for this reason, many users are reporting great success by starting with one or two bars of Papaya Kojic Soap then switching to the Glutathione Soap. For acne scars, dark spots or other forms of melasma, most users find the Diana Stalder Black Soap to be most effective. The Licorice Beauty Bar is the mildest of the four bars, followed by the Black Soap, Glutathione Soap and the Papaya Kojic Soap.
