RE:RE:What if....
the lightening one was pulled because of Hydroquinone. There are videos on youtube with agents showing how if they used the various regimes together (am and pm) then they could achieve 4% pharmaceutical grade effect with 2%. I suspect same for 1067. Very likely why Rodan wasn't fussed about waiting for .4% 1067, and why 1067 will be in more than one product. 2x or more sales.
