My skin post shower is the way it feels when I stay at a five hotel and hair is noticeably softer and less frizzy. Ditch the expensive vitamin c serums and invest in one of these bad boys. If i owned my home I would get one for the entire water supply. However since my shower is not connected to the tub, my daughter will have to settle for vitamin c tablets dissolved in her bath water. I am never washing my face in the sink ever again.
