Best serum ever! I love what this serum does for my skin. I use it at night and use serum C20 during the day. It not only firms and tightens but leaves my skin with such a nice glow. I pair this with a one of YonKa moisurizers including the Optimizer moisturizer, Phyto 52. or Nutri Defense, depending on what I feel my skin needs. Serums are so vital in your skincare regimen and this serum works.
