Very moisturising. I love the texture. It's lightweight and not sticky at all but is occlusive enough to seal in moisture. One downside is that if you have oily skin, this might make you break out. It may also not be good if you live in a really dry environment as the hyaluronic acid won't be able to get water from the surrounding environment. Also, for some people, smaller hyaluronic acid molecules can irritate some people's skin.
