I have been using Cristine Valmy products since 1972. In recent years as my skin has aged [extremely well thanks to your skin care and products], I have been using Valpeche at night. It was not available right now so the lady I spoke to said to try Cell Renewal as a substitute. It's not quite as great for my skin as Valpeche, but almost as good. So I am very happy to have it until more Valpeche is available. Thank you!
