I used this on my whole face for a couple of months until my face had properly rehydrated after years of using chemist bought products. Now I just use it on my eye area and neck.
What is most impressive about it though, is I had a "V" section on my chest, just below the neck, that was severely sun damaged from years of working outside. If I rubbed my finger across it I could feel lots of tiny lines, it was that bad. I used this on it every night, and it is smooth again. Unreal!
