I didnt like anything about this product, it only made my face greasy... no change in skin tone ..no effects of the hyaluronic acid, i even tried using it after my ost c20 vitamin c serum but it made no difference, the only positive i could talk about it it is a very big tub and will last you forever but sadly it is of no use to me, i have been using it  every night for 5 months now, and the quantity has barely reduced by 1 mm in the tub. i think i will stop using it now and look for a better moisturizer.
