First, I wish to clarify that I did not receive this product as a sample. I purchased it myself at a department store, despite what this form states below. I am, however, a Smart Rewards member so I may receive some points if my review is published. About a year ago at age 55 I noticed that I was developing some small (1/4" to 1/2"), dark patches of skin between my temples and eyes, particularly on the left side of my face, due to over-exposure to the sun. I had some smaller patches that were less noticeable on my cheeks as well. Additionally, I had a very small but even darker spot on the bridge of my nose, where for quite a while I had previously had a stubborn pimple. After using this product for a month, my cheeks began to even out in color and were almost free of spots. I continued to use the product, and at four months my temples became noticeably improved as well, and were completely clear and even in tone after six months of fairly regular use. The acne-related spot on my nose was more stubborn, but it continued to improve slowly, and after about a year it's hardly visible at all. I went through about two bottles of spot corrector during the year, and I'm now starting my third bottle, but using it less frequently to maintain my face's even tone and keep the spots away. At this rate, the third bottle should last me about a year. I admit that I was very skeptical about this product at first, but once I began to see results, I was a believer.Yes, I would recommend this product to a friend.
