What Hyaluronic Serum Is and Why Consumers Buy It
Hyaluronic acid is a naturally occurring polysaccharide that holds up to 1,000 times its weight in water, making it a central ingredient in hydrating serums. Consumers buy hyaluronic serum primarily for its ability to support skin hydration and reduce the appearance of fine lines. The global hyaluronic acid market was valued at approximately 5.3 billion USD in 2023 and is projected to grow through 2030, driven by demand in skincare and medical applications Forbes.
Serums typically contain low-molecular-weight hyaluronic acid to penetrate the outer skin layer, while higher-molecular-weight forms form a film on the surface to reduce transepidermal water loss. Formulation pH, concentration, and the presence of complementary ingredients such as niacinamide or glycerin affect performance. Regulatory oversight for cosmetics varies by region, with the U.S. FDA classifying these products under cosmetic guidelines FDA.
