I purchases this for myself, since my face is starting to sag, but I also gave my husband a few treatments. After 3 days, when returning from work, he commented that he couldn't believe the difference in his face and the reduction in wrinkles. I haven't seen a difference in my facial sagging yet, but it makes sense that would take longer. Also, I heard Suzanne state once that the booties can be rinsed and reused, which is what I've been doing...one pair lasted almost one week.
