A hydrating serum using sodium hyaluronate at several molecular weights alongside glycerin and panthenol. It draws and holds water in the upper layers of the skin, so skin looks plumper and feels more supple. It carries no exfoliating or resurfacing active, which makes it easy to pair with anything else in a routine.
Hyaluronic acid is a humectant: it holds water, it does not create it. In a dry room or a dry climate, apply it to damp skin and seal it with a moisturizer on top, or it can draw moisture from deeper in the skin and leave the surface feeling tight. It hydrates; it does not repair the barrier on its own.
