    "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 leaves skin feeling soft and plump. Many reviews mention improved skin texture and reduced dryness with regular use. The lightweight formula absorbs quickly, though some note it can pill under makeup. While most find it soothing for sensitive skin, a few report it didn't meet their hydration needs. Reviews frequently highlight its effectiveness for dry and reactive skin types. Common feedback includes appreciation for its smooth application and lasting moisture, though several wish for a larger bottle size.

    Not sure

    Love most of the Inkey products I have tried so far but this one is bit of an odd one, yes it does what it say on the tin in terms of calming skin down, but leaves sticky film on my face. Kind of like after using a mask. Rolling off and cannot be used on my face under make up, only nighttime, and I need extra moisturiser or gives mw odd tense skin sensation after application, like it's not absorbing but creating a film on you skin
