To be totally honest, I can't really tell a whole lot of difference. Partly because I had pretty good skin to begin with - my hairdresser has told me a couple of times (before I started using any BHMD products), "Gee, you have beautiful skin."
But - since I'm 73, maybe at least it's helping to maintain what I've had (and not go downhill).
Bottom Line: Yes, I would recommend this to a friend
