I started purchasing more Professional Solutions products after buying, and being very impressed by, the Sal/Gly Kit of theirs. The 100% Pure Hyaluronic Moisturizer was one of the items that came in the kit and I keep repurchasing it. Literally every moisturizer I’ve ever used causes my combo skin to become oily and shiny and makes my makeup just slide off my face. This stuff on the other hand doesn’t cause my skin to get oily or shiny at all. It is a clear odorless and gel like in consistency. I just put a few drops in the palm of my hand, run my hands together and then pat it on my face. It sinks right into the skin and feels like you never even applied anything, which I love. I read up on Hyaluronic Acid and found that Hyaluronic Acid occurs naturally (and abundantly) in humans and animals, and is found in young skin, other tissues. and joint fluid. Hyaluronic acid is a component of the body's connective tissues, and is known to cushion and lubricate. As you age, however, the forces of nature destroy hyaluronic acid. (found that on webmd.com btw.) I feel like I’m doing something really good for my skin when I use this, and aside from that, it does exactly what I need out of a moisturizer: it moisturizes my combo skin without making it oily and without breaking me out. At night I mix equal amounts of their Squalane with the Hyaluronic Moisturizer for extra moisturizing and I never get flakey skin anymore. The Squalance does make my skin shiney so I only use it at night, but it would probably do wonders for someone with very dry skin as a day treatment. I only have two negative things about this moisturizer. One is that it is 30 bucks for a little one ounce glass jar of it. I use it 2-3 times a day so I go thru it in about a month and that gets expensive, but it is worth it to me because its is literaly perfect for me. And the Second is that it comes in a litle jar with an eye dropper. Once you get low on the stuff it is impossible to get it out of the bottom with the dropper so you just have to turn it upside down and wait for it to come out that way. I can deal with that though, although it does annoy me when it happens. Overal, this stuff is amazing and I highly reccomend it.
