I have been using it for a week. I noticed a little difference after the 2nd use. I use the product after I exfoliate in the shower at night before bed. I use the product right after while my body is still warm from the shower so all the pores are open. I think this helps the body absorb the product better. I have been using it once a day. It has improved the sagging skin a little bit and I am happy with the way the product has been working. It makes the skin soft and silky too. The smell is not the most pleasant and you don't get much in the small bottle. I also wasn't clear on what (2-pack) meant. I thought I was getting 2 bottles but only one arrived. 3.5 ounces is all you get.
