Well, I received my Youthful Essence kit. They said delivery is 4-6 weeks but I got in in about 5 days. I've used it twice and have to say I can already see a difference. It really does smooth things out, takes off that dulling top layer. My make up goes on better and looks better after it's been applied. Seems to work well for that sun damaged area of my chest. It's very easy and comfortable to use. And quiet, I was worried it would be LOUD. My only complaint so far is rinsing the crystals off once you are finished. The cream gets worked into your skin during the exfoliation and just the crystals are left behind. It's easiest to do just before getting in the shower, but that is not always convienent. If you can't get in the shower after, plan on spending some time rinsing and rinsing. When you do your neck and chest at the same time, all that rinsing can get to be a mess. Other than that, I'm happy with it.
