Query: Firming Fluid

I have sensitive skin and must state that it does not cause any irritation whatsoever. Unfortunately, for my case of deep set wrinkles in my neck, I did not notice much of a difference. The price here, however, is quite competitive, as I saw it being marked up considerably at the stores in the area. Did not do much for me, but for this price, might as well try it!
