I discovered this product when I lived in the dry high desert of northen New Mexico and I now live in Denver, also dry. I have been using it for 15 years and I find this stuff keeps me looking years younger than I should. I have no new wrinkles in the last 15 years and I am in my mid fifties. I have tried to go without it but always come back. One tube lasts me about 6 months. I haven't tried all the amazing stuff here at spalook so I cannot say how it compares but can say that it really works for me. Feels great and keep my skin very healthy and young. Best price is here.
