I've been using this a little over 3 1/2 weeks and absolutely love it. I work long hours and get minimal sleep at night which causes large dark circles under my eyes as well as puffiness. I also have dark spots on my chin from acne breakouts. I saw lighter eyes and chin around week 2 and it gets slightly lighter every few days. It's easy to use and doesn't have a crazy smell so nobody knows I'm wearing anything on my face. The puffiness has gone down in my eyes which others have noticed. My boss asked me what's changed in my life that I'm getting the sleep I need. I like this this is a natural product that was made in the USA. I don't use anything that's been tested on animals or made in other countries. Overall I'm satisfied and hope finishing off the bottle completely removes all the dark spots and circles.
