I got this serum as a bonus with my purchase and it's been very soothing on days where I've been out in the sun. It's got a bit of a tacky dry-down texture which is fine because I put it on under a face oil. I like that it's fragrance free. I'm not sure I notice a big difference in hydration but I haven't been using it consistently so that's on me. I wish it came in a different applicator as I often find that I've dispensed more product that I need but I put the extra on the back of my hands.
