Great for helping dry 40's skin
Has helped my dry skin a lot!

I've used it a couple of times and it does plump, but the fragrance is so bad it burns my eyes if I get anywhere even close, so I suspect it's a marketing strategy so that you buy their fragrance free eye formula in addition to this. Likely going to return.
so far so good with moisture!
no complaints so far! Been using for a week for added moisture and the dry patch is gone!
