H2O+ is a line of oil-free skincare products that uses ingredients derived from the sea to hydrate your skin. I recently tried Face Oasis ($34), which claims to deliver the moisture equivalent to eight glasses of water to your skin.
The formula has a gel-like texture, with a faint but pleasant salty-sweet smell. It goes on medium in weight — not as light as a serum, but smoother than a moisturizer. It takes a few minutes to settle into the skin, and can get a little sticky while drying. But when it does dry completely, your face feels velvety soft.
This hydrator can be used either as a daily moisturizer, or you can apply a heavy layer and use it as a mask. Since it takes a while to absorb fully into the skin, it's not going to be a part of my morning routine, but it's great as a nighttime hydrator.
