  • 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.

    Good so far

    It makes my skin look very good but it is hard to pump out of the small bottle. Also, I do not like the smell but if it ruins the product to change the scent then it is not too bad and the smell goes away. But if it doesn’t change the efficacy, I would personally want a customized better smell and also no fragrance versions too if that is ok with other people etc. Thank you
