This is a holy grail serum/moisturiser for me. The description says it's for mature woman who have dry skin and it promises to diminish wrinkles. I bet mature woman, though I have no idea what age is considered to be mature, deeply enjoy this, nonetheless, as a young woman having spot prone and combination skin, I don't enjoy this blend any less.
I use it after (if I happen to use) serum either on its own or under a moisturiser. For me, one drop is more than enough for my entire face.
It comes with a high price tag but I think it's very worth the investment in terms of performance. It's organic too, if that's your thing.
