Science
Mechanism of Action
This ingredient functions by providing essential amino acids to support the skin's Natural Moisturizing Factor (NMF), thereby promoting sustained hydration and elasticity. It actively stimulates collagen synthesis, offers broad-spectrum antioxidant protection against environmental stressors, and helps to visibly diminish fine lines for a more youthful appearance. Furthermore, it contributes to a brighter complexion by targeting dark spots and uneven tone, while its anti-inflammatory properties calm irritation and reduce redness. It also regulates sebum production, acting as an anti-irritant and imparting a refined, smooth finish.

The Formula
Formulation
Stability
Hydrolyzed rice protein exhibits pH-dependent solubility. Aggregation and insolubility are observed near its isoelectric point (pI), typically between pH 5.0 and 6.5. Optimal solubility and stability are achieved in acidic conditions (e.g., pH 3.0-4.5) where it maintains a positive charge, or in neutral to slightly alkaline conditions (e.g., pH 6.5-8.0) where it carries a net negative charge, both preventing aggregation. Increased solubility may also be seen at higher pH values, specifically 10-12.
