    Hydration Hydration Hydration!!!

    The hydration I've had in my skin since using this serum has been insane. So much so I've stopped using Hyaluronic acid. I love how it sinks in, repairs my skin barrier, how plump my skin feels after 10 minutes. I absolutely love this serum, can't be without it! Thank you Inkey list!!!

    Double bliss!

    I would not be surprised if these serums sold out fast! I was a fan from the first couple of days of trying this serum. So much so, that I just had to buy the duo pack.

    Why not 5 Stars? My only problem is that It's difficult to see how much serum is left in its container.
