I enjoy these products however had the weirdest customer service response! After buying Stemnucell for the first time and having CE Ferulic as my daily regime, I called to ask what order I am to apply these or if it is ok to apply them together. The answer I got was "try it and see what happens" , Not good!! I then asked to speak to corporate and was told that was not possible. I asked where the products where made, The person assured me it was in the US but told me "I am not allowed to divulge this information" like it was some clandestine affair. I do believe I have a right to know where the products I purchase for my skin are made! I am hesitating to continue buying these products despite how much I enjoy them. Please clarify if you want to continue my business. If I do not get a reasonable response then I will use up what I have and move on to another product. Thank you.
