  • 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."

    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
