Plexaderm works! I've spent money on numerous products that purport to tighten skin and reduce lines. I was hesitant to spend another dime but am so pleased that I purchased Plexaderm. I use it for firming under eye bags and drooping chin. It's fabulous. Putting on plexaderm in the morning and lasts all day long. I'm wearing less makeup and results are noticeable to my family. If you are thinking about using this product but hesitating at the cost, it's worth every cent! Long lasting and just a pea sized portion is all I need. I will continue to use plexaderm as my daily skin regimen. I love it!!
