    This cream is amazing

    Leaves my skin smooth and isn't at all greasy. I use it before the bio-active ceramide and my dry skin is much better now.

    Not that impressed - still struggling with dry patches

    I’ve used this twice daily as part of my routine for weeks, but unfortunately the dry patches and fine lines on my face have gotten worse!

    Excellent addition for my skin.

    I confess that I was feeling a little cynical, upon hearing that this product was what my skin was waiting for!

    Fast forward a month & from the first day, my skin did enjoy this serum. I didn't think that this serum would do all that the write-ups said that it could.

    Well, my skin definitely loves it & I have just received my latest order, for a duo pack of EH- Barrier Serum. Thanks.
