I can't believe it's been one year since we launched our Glass Skin Refining Serum. My biggest hope when developing this serum was to create a toxin-free, high-performance, delightful product that would make it easy for all of you to achieve your best skin yet. Essentially, that means skin that appears so poreless, luminous, and translucent, it looks like a crystal-clear pane of glass — hence, glass skin.
