Authentic TNS skin medica sealed and fresh, purchased directly from the Dermstore website. Expires 7/24.. only reasonable offers will be accepted this is an authentic product that is sealed and fresh the only reason why I’m selling it, is because I have auto ship and I received it faster than I needed it. So if it doesn’t sale soon I’ll just cancel the listing and gladly keep it. It has really helped my skin.. this is the best anti aging serum on the market..
