This stuff is magic. It goes on easy for a serum; a little goes a long way so the product lasts a long time.  It’s a bit on the pricey side but worth every penny. I’ve been using for almost a year now; it’s the one product I won’t go without (it is that good).  It can be applied under makeup as it absorbs almost immediately; and, it is great before applying a daily moisturizer or night cream. I noticed results after about one week. It really does perform what the product claims to do. 

Its really a good and hydrating product. But its very expensive for what it does. If it was less expensive I would buy it again.

I've lost track how many bottles of this serum I have gone through. I have dry sensitive skin and it is one of the few hydrating serums I have found that don't break me out, absorb flawlessly and leave plumper happier skin - especially with repeated use. There are less expensive "dupes" but every time I try them I instantly regret it and go back to this.

I didn't really FEEL or see a difference using this. Maybe I didnt give it enough time? But for an expensive bottle like this I would expect more.

I actually stumbled across this serum when I was obsessed with stem cell formulas. I got on sale with a coupon for a really good price. It made my skin soft and supple. The only drawback is the price. That's why 4 stars instead of 5. Otherwise, I would use it regularly as it was definitely beneficial to my over 55 skin.
