Science
Mechanism of Action
This lipoamino acid functions by bolstering the integrity of the skin's protective barrier. The palmitoyl group, a key lipid anchor, significantly improves its epidermal penetration due to increased hydrophobicity, fostering a strong affinity for cellular membranes. Simultaneously, the alanine component actively aids in skin hydration and exhibits inherent calming properties, collectively promoting a more robust and soothed skin state.

The Formula
Formulation
Stability
While a specific optimal pH range for Palmitoyl Alanine was not explicitly defined, related lipoaminoacid formulations generally maintain stability between pH 3 and 8, ideally targeting a pH of approximately 5 to align with skin's natural acidity. The alanine constituent is generally incompatible with strong oxidizing agents, which should be avoided in co-formulations. Overall formulations should be developed to be non-irritating.
