Bests & Worsts Reviews from Amazon

I bought this because of the large number of positive reviews for it. Maybe it just didn't work for me but I used the product for 4 weeks exactly as described and then started using it morning and night and putting on a lot more for 2 more weeks and still have not noticed any difference at all. It is as thin as water but feels a little sticky when I apply it. I only have fine lines so I would expect that they would be less noticeable but I think they are actually more noticeable recently. Also, note that it says your money will be refunded with no questions asked if it doesn't work, but apparently that simply means you can return it with in the standard Amazon 30 day window for returns. After that, they will not refund it even though it says you need to use it for at least 30 days to see results. So, if you aren't seeing any difference after 3.5 weeks, make sure to return it then. Edited to add an update: Because I take posting negative reviews for a product seriously, I continued using this product for 11 months to see if there would be any improvement over time. I still did not notice any difference. So, it may work for some but didn't work for me and I have switched back to using Olay Regenerist Serum which worked better for me.
