Hyaluronic Acid Supplier South Africa

Chii chinonzi Hyaluronic Acid?

Hyaluronic acid (HA) is a naturally occurring polysaccharide (glycosaminoglycan) found throughout the human body — most abundantly in connective tissue, skin, and synovial fluid. Its most remarkable property is its extraordinary water-binding capacity: a single gram of hyaluronic acid can hold up to 6 litres of water, making it the most effective humectant in cosmetic science. In skin, hyaluronic acid is a major component of the extracellular matrix and is responsible for the hydration, volume, and elasticity of healthy skin. It is supplied commercially as sodium hyaluronate (the sodium salt), which is water-soluble and stable in cosmetic formulations.

Molecular Weight and Skin Benefits

The molecular weight of hyaluronic acid determines how it interacts with the skin. High-molecular-weight HA (>1 MDa) forms a hydrating film on the skin surface, providing immediate surface hydration and a smooth, plumped appearance without deep penetration — ideal for surface moisturisation and anti-wrinkle serums. Low-molecular-weight HA (≤50 kDa) penetrates into the upper layers of the epidermis, providing deeper sub-surface hydration. Ultra-low MW fragments may penetrate more deeply and exhibit additional biological activities. Multi-weight HA complexes (combining two or three MW grades) are used in premium serums for layered hydration across different skin depths.

Pharmaceutical and Injectable Applications

Pharmaceutical-grade hyaluronic acid is used in ophthalmic surgery (as a viscoelastic), in injectable dermal fillers for volume restoration and wrinkle filling, and in intra-articular injections for osteoarthritis treatment (viscosupplementation). Cosmetic-grade HA is used in face serums, eye creams, sheet masks, moisturisers, and lip care products. Terracore Chemicals supplies cosmetic-grade sodium hyaluronate in multiple molecular weight grades for South African personal care manufacturers.
