Science
Mechanism of Action
These amino acids primarily act as powerful conditioning agents for both skin and hair. As fundamental building blocks of proteins, they are believed to bolster the skin's Natural Moisturizing Factor (NMF), enabling the skin to attract and retain essential moisture. This action significantly improves overall skin hydration and reinforces its protective barrier. While distinct from jojoba oil, their origin suggests potential synergistic effects, possibly contributing to anti-inflammatory responses, improved skin repair through pro-collagen III and hyaluronic acid synthesis, and antioxidant defense.

Stability
While no specific optimal pH range for stability was identified, Jojoba Amino Acids are derived from completely hydrolyzed jojoba seed protein. As protein hydrolysates and amino acids, they are generally water-soluble and exhibit stability across typical cosmetic pH ranges.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Jojoba Amino Acids 'safe in the present practices of use and concentration' within their assessment of plant-derived amino acids. While no maximum concentration was specified, amino acids are typically used at low levels in cosmetics and are not expected to cause systemic reactions. Furthermore, general L-amino acids hold 'Generally Recognized As Safe (GRAS)' status as direct food additives by the FDA.
