"With a 10 being a perfect score I gave this one a nine. It's lovely and I think a lot of people have really good luck with this, and if you're on a budget it's really budget friendly too."

"Polyglutamic acid is essentially multiple glutamic acids stringed together and it's a very large molecule, great for drawing water to the top layer of the skin. Some argue that polyglutamic acid is four times more potent than hyaluronic acid. It's a great, slightly underrated humectant. This serum contains three percent polyglutamic acid along with glycerin, two wonderful humectants, as well as rice bran extract which has soothing properties, hydrating properties, and even arguably some brightening properties. It's a really wonderfully formulated, lightweight, hydrating serum that is really suitable for all skin types. It's a really nice, lightweight, non-sticky hydrating serum, so great for individuals looking for a hydrating serum that doesn't contain hyaluronic acid. It's great for improving fine lines and wrinkles, temporarily plumping the skin, and improving dry skin as well as dehydrated skin."
