Sodium Hyaluronate (Hyaluronic Acid Fermented by Lactic Acid Bacteria)

Origin

A sodium salt of hyaluronic acid obtained through a biotechnological fermentation process using lactic acid bacteria.

This sustainable, non-animal method ensures high purity, biocompatibility, and ethical sourcing, aligning with modern skincare science and environmental responsibility.

Skincare Benefits

Hyaluronic acid is often referred to as a “moisture magnet” — capable of binding 2 to 6 liters of water per gram.

It exists naturally across multiple layers of the skin, where it plays a vital role in hydration, elasticity, and structural support.

In the dermis, hyaluronic acid serves as part of the extracellular matrix, maintaining tissue flexibility, supporting cellular architecture, and regulating moisture levels.
Within the epidermis, its concentration increases toward the upper layers, facilitating the transport and diffusion of oxygen, ions, nutrients, bioactive substances, and metabolic by-products.
In the stratum corneum, it contributes to water retention and interacts with intercellular lipids, helping maintain optimal hydration balance.

With age and exposure to ultraviolet radiation and environmental stressors, hyaluronic acid levels in both the epidermis and stratum corneum decline — leading to dryness, dullness, loss of elasticity, and visible fine lines.

When the stratum corneum’s water content drops below 10%, cracks and roughness appear, underscoring hydration as a defining factor of skin beauty.

Sodium Hyaluronate provides superior moisture retention that remains stable even under humidity fluctuations. It forms a lightweight, lubricating film on the skin’s surface, reducing transepidermal water loss (TEWL) and imparting a smooth, supple texture.

When combined with glycerin, it produces a synergistic and prolonged hydrating effect, visibly improving texture, suppleness, and luminosity while reducing roughness, fine lines, dullness, and enlarged pores.

Furthermore, pairing high-molecular-weight sodium hyaluronate with low-molecular-weight hydrolyzed hyaluronic acid enhances absorption and penetration (into the stratum corneum), optimizing both immediate and long-term hydration.

With over 30 years of proven cosmetic use, sodium hyaluronate is considered safe, non-irritating, and universally compatible with all skin types.
