I didn't really know what to think about this DNA Serum and Viper Venom. I watched videos and read about it. I figured I would give it a try cause people seem to have great results from using it. I guess in a way it's kind of like Botox so to speak. I have some crows feet and a few lines around my eye area. I started small just to test it on my forehead. After just a little while I could see results it was like they were fading and it made my skin look firmer. I am looking forward in continue use for more results that I am sure will come.
