      Smooths out UnderEye

      After I put on the Collagen Elastin, I always finish off with Algae Serum. I have found after Washing my face dry clean and using the 2 products leaves under my eyes a tightened feeling with few fine lines showing.

      Must have product

      The New + Improved Algae Serum is a staple in my skin care routine. The light but milky/creamy formula absorbs completely into my skin & is not at all greasy so it's a great product for my skin even in the summer. It also doesn't leave my skin feeling sticky like some serums do. I used the "Algae Serum" for years & was glad to see a new & improved version rather than it being discontinued.
