I received this and one of my monthly subscription boxes probably a year or so ago and I've been using it off and on since then. At first I used it on my face but it smelled so bad I couldn't get past the smell. The smell totally lingers it never goes away. So I started using it on my chest and have been using it for a while and I've had no results on either my face or chest. It's also kind of sticky and slimy, so I definitely didn't like that either. But since it's such an expensive product I thought that it was worth pulling through and being a soldier and dealing with the smell but unfortunately that was not the case. I would not recommend this save your money. Now if you happen to get it for free in a box give it a try if you can deal with the scent. Oh one good thing is it does last a while. I still have a little bit left, I just threw it in the trash because I'm just over it. But it only takes a little bit, it spreads nicely, and goes a long way. I probably used it four times every week for the past year and I would say that there was still a tenth of the bottle left.
