    "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."

Reviews Summary
Customers say this serum provides deep hydration and absorbs quickly into the skin. Many reviews mention improved skin texture and plumpness after regular use. The lightweight formula works well for most users, though some note it can pill under makeup. Frequent comments address the smooth application and non-greasy finish. While most find it effective for dry and sensitive skin, a small number report it didn't provide enough moisture. Reviews particularly highlight its soothing properties and compatibility with other skincare products.

    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.
