Bests & Worsts Reviews from Amazon

I admit, I was skeptical to read a handful of reviews questioning the authenticity of this product, but after comparing it to one that I got from an authorized retailer (Dermstore), I can confirm that the product I received from the Amazon seller is different. It may just be an older formulation (vs counterfeit) but it IS a different formulation nonetheless. The packaging is a large box vs small, the ingredients listed are slightly different, the color is orange tinted (vs almost clear for the Dermstore one), and it lacks the distinctive scent and "tingle" of the authorized one. I've posted side by side comparison photos to show the physical differences. The Amazon one in on the left in all the photos.
