    Muito bom

    Já utilizava o normal que adoro, mas ainda gosto mais deste por ser mais hidratante ainda, tal como o outro deixa a pela muito suave, muito hidratada durante todo o dia e pele muito bonita e saudável.

    Tenho 58 anos e pele muito seca.

    Very good, absorbs well!

    I was surprised by how much I liked this as I LOVE One Skin FACE so much. On a whim I decided to try it and now I use it everynight and use the FACE product in the morning.

    The dispenser, just tickles me--it dispenses just the right amount of product! Only thing I am not sure of is how when you get down to the end of it, can you open the jar to scoop out the rest? That is the question....with the OneSkin Face, it is easy to cut the foil tube open so you can use every last drop--not so sure this will be as easy.
