I wouldn't say its super hydrating, but as someone with combination skin I didn't notice my foundation clinging to the dry spots (which can sometimes happen when I use other primers under my foundation.) (maybelline.com)
Unlike a lot of other primers, this one looks and feels a lot like a lotion / moisturizer. (maybelline.com)
Unlike other primers on the market, this one contains no silicone, which I actually like (again due to breakouts which can be caused by this ingredient). (blushingrosestyle.com)
