    "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.

    Amazing!

    Leaves my skin feeling soft silky and glassy! It melts into my skin and it’s sticky! Gives a long lasting hydration! Also goes great under makeup! And my makeup stays nicer!
