    "Magic Potion! My menopausal skin crisis happened just as this product was launched. My skin was suddenly reacting to products I had used for months/years. It was red, dry, flaky and thick. I took a chance and bought the Ectoin Hydro-Barrier Serum to see if it would help. It did an amazing job of calming my skin."

    Great Addition to Ant Aging Routine

    I am always looking for ways to keep my skin hydrated in my high desert location. This has been a great addition to my routine along with Inkey's Exosomes Hydro-Glow Complex and Bio Active Ceramide Repairing and Plumping Moisturizer. Inkey makes it so easy to try new products and develop a personalized program because their prices are nothing short of AMAZING. I'm a fan for life.
