I just recently received my 1st autoship refill of this product. I've not used it completely faithfully day/night, but I have done much better than I normally do using products with the frequency as directed. I am overweight and have fat under my chin, not just sagging skin. Of course, the fat isn't gone, but I have noticed a more toned, tighter look to my neck area. I'm gonna keep using this for a while longer.
