Jan Marini Peptide Xtreme
I have been using various products in the Jan Marini line. After 22 days of use, I do not observe any difference in my skin. I will continue to use it until the bottle is empty. If no changes are observed, I will not reorder and will then provide my comments and ratings based on my performance.

I love using this as part of my nightime regimen. It makes my face feel soft and plump.
