    "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."

    Great stuff

    It helps plump my face. It's really great stuff. I'm turning 44 this year and I'm finally feeling confident in my skin.

    Okay

    I haven’t used this much as it makes my other skincare and make up pill. I can only use this at night so not haven’t much of an effect
