I bought two bottles. I have used it now for 8 weeks. I am just now beginning to see some results. I have a couple of prominent dark spots on my face, which I really am targeting. After the first month, I was discouraged but kept going. Now I feel like I will order another bottle and see what happens. Definitely you should be consistent with twice a day use. I put it on and let it dry awhile before putting on my makeup for the day. Then again right before bed. I will report again in a month or so.
Bottom Line: Yes, I would recommend this to a friend
