I've been buying PanOxyl Acne Foaming Wash for a few years now on the advice of my dermatologist. It has worked wonders for my skin and scalp. Unfortunately , the latest three-pack that I received from Amazon is the "New Formula" version. It stinks, both literally and figuratively. The smell is strong and unpleasant, and it has a new, more watery consistency that does not foam nearly as well as the original formula. Not pleased at all. Why do companies feel compelled to screw around with an existing, proven product that is already a winner?
