I bought the smaller bottle, just to try it first. The product consistency is just right for easy application, and it does not have any scent, nothing that I can detect, at least.
It's just my 3rd day using it so I can not comment yet on any result, but I like the product overall. I use it at night after cleansing and before my night cream, and I wake up feeling (at least!) that I have great skin even if I'm in my late 50s.
