    "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 absorbs quickly into the skin. Many reviews mention improved skin texture and plumpness after regular use. The lightweight formula works well for most users, though some note it can pill under makeup. Frequent comments address the smooth application and non-greasy finish. While most find it effective for dry and sensitive skin, a small number report it didn't provide enough moisture. Reviews particularly highlight its soothing properties and compatibility with other skincare products.

    This is a miracle

    I swear this can't be real. I've applied it, as advised, for only 5 days now, and I can visibly see the difference! I couldn't believe it, but people have mentioned seeing a difference. Well, we still have room for improvement but I fully trust that it will help tremendously with my horribly dry, dehydrated skin, with more time using the product. It is an exceptional product, at a very good price, and I am extremely happy if you couldn't tell already.

    Not sure

    Love most of the Inkey products I have tried so far but this one is bit of an odd one, yes it does what it say on the tin in terms of calming skin down, but leaves sticky film on my face. Kind of like after using a mask. Rolling off and cannot be used on my face under make up, only nighttime, and I need extra moisturiser or gives mw odd tense skin sensation after application, like it's not absorbing but creating a film on you skin
