Is there any negative outcome from becoming dependent on this product? Does it alter the skin's natural performance?

I have thought about trying out this product, but I haven't yet given in to the temptation yet. I am not too old, but I realize that I am aging as well; I also want to maintain my youth. I am also concerned about the outcome of my skin. My real concern is the use of mysterious products on the surface of my skin. scientifically, I thought that the skin healed from within, and underneath the epidermal layer; I was told by my professor that the skin's top layer is just mostly dead skin. I just want to know if the use of this product will be beneficial scientifically, and how?
