anti-aging products that have actually worked for me include garnier - the ultra lift pro x. It comes as a roll on and it didnt have collagen in it like all the other products. Instead it has a beech tree extract. I had incredible results with this when I first used it and have used it since. In fact, it was one of the cheaper varieties and I have always been on the look out for something that works better, but haven't found anything.
I am concerned that all of the myths about collagen are true and that collagen in creams cannot penetrate the skin and even so it cannot bind with the collagen network underneath the skin.
That's my input
