Since my skin has problems with creamy or lotion moisturizers, I am stuck using serums and essences instead. This is a very hydrating essence which keeps my skin nice and glowing. It is better than pure hyaluronic acid because HA needs other stuff on top of it to draw moisture in, and since I cannot use moisturizers, I have to use this essence instead. Nevertheless, it does its job and does it well! I will definitely be repurchasing it.
