I've just been taking this supplement for about a month now. But, I have noticed some difference in facial skin. I've read the warnings, I've read the benefits, and I'm making a personal choice to keep taking this for a few more months. At the very least I hope it helps in other areas of my body. Do your research because this may not be for you. Neocell is a top rated brand and affordable. Only thing I don't like is how huge the pills are and how many you are supposed to take each day. Other than that, so far so good.
