  • Before and after comparison
    "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 makes skin feel plump and smooth. Many reviews mention improved texture and reduced dryness with regular use. The lightweight formula absorbs quickly, though some note it can pill under makeup. While most find it gentle and soothing for sensitive skin, a few report it wasn't hydrating enough for their needs. Common feedback highlights its effectiveness when used on damp skin and as part of a layered routine. Reviews are particularly positive about its smoothing effects and ability to enhance skin's natural moisture.

    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!

    MY SAVIOUR

    Due to use of another product, my skin barrier got absolutely demolished. With constant use of only this product and a rich moisturiser , I was able to reverse that same in a little over a week. Now I now that prevention is definitely better that cute and that this serum will be a staple in my skincare routine!!
