Great product, normally I don't see much of a difference in face creams, serums, etc. However I always use them because I feel I need them, even though I don't (yet) have a lot of wrinkles, lines etc.
However, I purchased this as I noticed I started to re-like some H2O products again and my skin felt very nice and moist when I woke up which lately it had been having some dry patches here and there (yet overall I am more oily than not) and this nipped it in the bud. However, the biggest difference is that while I can't say I noticed a difference using it daily, it's when I skip a day that I notice, BOY do I notice. My skin looks drawn out, less plump! My skin is brighter too.
I will re purchase.
