This serum is excellent at hydrating skin. I first discovered it when being treated at a top spa in Sausalito. This serum is perfect for everyday use, and I can't travel without it. Apparently, you want to use serums and not moisturizers or water spritzers on airplanes because those suck moisture out. Not oily, no strong scent. Perfect!
