I was quite shocked as to how good this serum actually was. I really like the brand in general so I knew I wouldn't ever be let down, but this stuff seriously blew me away. It feels like you have had a really good sheet mask on your face for about 10 mins, its that level of hydration! I have used so many different hyaluronics before and usually price does make a difference with them. I think this one can easily match up to the more high-end products, if not better. I love it!
