Science
Mechanism of Action
Functioning as a large sugar molecule, Sodium Chondroitin Sulfate creates a protective, water-binding film on the epidermal layer, offering a robust moisturizing effect comparable to Hyaluronic Acid, with a superior affinity for the skin's surface. This action helps to retain moisture, maintain skin suppleness, support natural repair processes, and replenish vital mucopolysaccharides for a smooth, soft, and refreshed complexion. Its large molecular weight generally limits penetration beyond the epidermis in topical applications, while also exhibiting anti-inflammatory properties.

The Formula
Formulation
Stability
This ingredient is hygroscopic and performs optimally within a solution pH range of 5.5 to 7.5.
Conflicts
- Contamination potential with other polysaccharides, proteins, or infective agents is a concern, dependent on the animal origin and purification methods, which can compromise product purity, biological efficacy, and manufacturing consistency.
Safety
Safety Profile
Sodium Chondroitin Sulfate generally demonstrates an excellent safety profile. The U.S. FDA has designated it as 'Generally Recognized As Safe' (GRAS) for dietary use up to 1200 mg/person/day, and an injectable form is FDA-approved for ophthalmic protection during eye surgery. While specific safety assessments from CIR or SCCS for topical cosmetic use are not currently available, it is not listed on EWG's restricted substances and Environment Canada considers it not to be toxic or harmful.
