Stiefel Laboratories stopped producing the "ZNP Bar" in 2010. We don't know why. The product was well liked by professionals in the medical community and the public. Stiefel Labs was acquired by GlaxoSmithKline in July 2009 to create a new specialist dermatology business. Glaxo, we gather by their actions, was uninterested in the soap business, likely due to lower margins and lots of competition. Availability of Stiefel Labs ZNP Bar ceased shortly after the acquisition. They also discontinued SAStid (their Salicylic Acid and Sulfur soap), Acne-Aid, and their Sulfur Soap. PanOxyl (the BPO cleansing bar) went into short supply in 2012. Zeasorb was discontinued in the UK in 2013. And the formula for the PanOxyl foaming wash was changed in 2018 leading to lots of consumer dissatisfaction. On the flip-side, we love our business and plan to make our products for many years to come. The DermaHarmony Pyrithione Zinc soap is very similar to the original Stiefel Labs ZNP. Many customers of ours say that they like our soap as well or better than the original ZNP bar. Others say that the liked the original. Give us a try and let us know what you think.
What happened to the old ZNP bar & brand?
