Review on 🧴 Pure Hyaluronic Acid Serum for Skin: Intense Hydration & Anti-Aging - 100% Pure, Pro Formula - 2 oz by Mike Bray

Works great in humid climates and does the complete opposite (ie, dries out skin) in dry climates. I wasn't aware of that when I bought it. I live in California and when I first started using it I wasn't impressed. At best, it didn't do anything to my face. Then I went on a 25 day beach vacation in a very humid climate, took it with me and it worked wonders. Then I came back and he almost dried my skin to cracks. So I did a little research. Base Hyaluronic Serums can only be used in humid conditions. They draw moisture from the air to your skin. In dry climates, they simply help wick moisture from the skin. For successful application in dry climates, hyaluronic acid serum must contain CD44 molecules (low-molecular hyaluronic acid). the climate is dry.
