Review (4/5): the wrinkles are diminished and I am very happy with the effect
I am using the Oz retinol and combine it with the Oz Vit C Serum and put it on together. My face tolerates it very well, there is no stinging or redness. I have seen improvement in my face, it's tighter, the wrinkles are diminished and I am very happy with the effect. The diminished wrinkles effect lasts for quite a while, and I hope with continued use that the wrinkles will stay away longer and longer.
