Hyaluronic Acid Serum: What It Actually Does for Skin

Hyaluronic acid is a humectant that can hold up to 1,000 times its weight in water, helping skin retain moisture and supporting a plumper, more hydrated appearance. The Glow Booster Intense Complex Hydration Serum uses three molecular weights of hyaluronic acid together, so it works at multiple layers of the skin rather than just the surface.

What Hyaluronic Acid Actually Does

Hyaluronic acid is a humectant, a molecule that attracts and holds water. It occurs naturally in skin, but production slows with age, starting as early as the mid-twenties. Applied topically, hyaluronic acid helps skin retain moisture and supports a plumper, more hydrated appearance. It does not exfoliate and it is not an active acid in the way glycolic or salicylic acid are, despite the name.

Why Molecular Weight Matters

Not all hyaluronic acid behaves the same way on skin. Molecular weight, essentially the size of the molecule, determines how deep it can go. Larger molecules sit on the surface and hold moisture there. Smaller molecules can reach further into the skin. A formula that combines multiple weights works at more than one level at once, rather than only hydrating the surface.

How the Glow Booster Uses This

The Glow Booster Intense Complex Hydration Serum combines three forms: a low molecular weight hyaluronic acid that reaches deeper layers, a high molecular weight form that holds moisture at the surface, and a hydrolyzed form broken down for faster absorption. Thirty botanical extracts, including Blue Sea Kale, support the formula alongside it.

What to Expect on Skin

Hyaluronic acid helps skin retain moisture and supports a smoother, more even texture over time, particularly for skin that feels tight or looks dull from dehydration. It reduces the appearance of dryness rather than treating a skin condition, and results build with consistent use rather than appearing overnight.
