Science
Mechanism of Action
This ingredient functions as a skin-conditioning agent and humectant, mimicking the skin's Natural Moisturizing Factor (NMF) to attract and bind water within the stratum corneum. Its esterified form enhances lipophilic affinity, improving skin softening and barrier reinforcement while facilitating active ingredient penetration.

Clinical Evidence
High confidenceN/A
Key findings
- 01 Clinical studies on amino acid ester blends demonstrate significant improvements in skin hydration and moisture retention.
- 02 Research indicates enhanced penetration of other active ingredients due to its modification of the stratum corneum's lipid bilayer.

Stability
Most stable within the physiological pH range (5.0-7.0). Extreme pH (<3 or >9) or prolonged high temperatures can lead to hydrolysis.
Synergies
- Active ingredients (enhanced penetration)
Conflicts
- Strong oxidizing agents
- Strong acids
- Strong bases
Safety
Safety Profile
As a derivative of endogenous amino acids (Aspartic Acid, Glutamic Acid, Glycine), it exhibits a high safety profile with low systemic toxicity.
