    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.

    Skin Saviour

    This has been a skin saviour, I found I was damaging my skin barrier using a to strong cleanser (not this make) then this product came up by email, thought give it a try.

    It has made a such a difference to my skin, sinks in well, no grease, skin looks so much better.

    I am now using the oat cleansing balm and the hyaluronic acid cleanser as a second cleanse, will keep using these products for the results.

    Such a difference.

    This serum has made such a big difference to my skin in such a short time. My skin feels comfortable and soft immediately after application, and this feeling stays with me all day, unlike with other products I've tried. I've already repurchase so that I don't run out.
