I wasn't overly impressed with this serum. I didn't notice much of a difference in the 'plumpness' of my skin at all. I do like how it applies smoothly and makeup goes on evenly after using it. All in all it's an okay product but it didnt live up to it's claims, at least not for me. For the price it's just not worth it to me. I like Kiehls products but this one was a miss for me.
