    "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.

    Great serum for skin barrier

    I've had problems with damaged skin barrier for years. Most products I've used either did nothing or clogged my pores. I was looking for a light product I could use in the morning and that would still be effective, because a lot of products with light texture don't do much for my skin. I've seen a big difference with this product and it really helps with the skin barrier.
