This is a lightweight serum that goes on smoothly. I have super sensitive skin and was worried about irritation or burning. I didn't have an issue with either. It also didn't leave me fire truck red like so many other products. Also it doesn't have a chemical scent like other products. I love how "clean" the ingredients are compared to similar products. I'm not plagued with tons of wrinkles or fine lines, so I'm using this more as a preventative. So far, I'm impressed. I'll up date my review after continued use.
