Science
Mechanism of Action
Arginine acts as a foundational component for skin regeneration and protection. It serves as a precursor to nitric oxide (NO), enhancing microcirculation, which is vital for nutrient delivery and oxygenation. This amino acid exhibits potent antioxidant properties by neutralizing free radicals, thus mitigating oxidative stress and contributing to anti-aging effects. Arginine also actively stimulates collagen production, bolstering skin elasticity and structural integrity, while its humectant properties significantly improve skin hydration and fortify the skin barrier. Although 'ARGININE DNA' is not a standardized cosmetic ingredient, Arginine itself is known to interact with DNA by promoting its dense packing, influencing thermal stability, and stimulating DNA synthesis during wound healing, thereby supporting cell proliferation.

Key findings
- 01 Topical L-arginine at 15% concentration demonstrated improved mechanical resistance of the skin and enhanced collagen and elastic fiber formation in aged female mice.
- 02 Arginine, when topically applied between 0.5% and 18%, significantly alleviates clinical symptoms associated with dry skin.

The Formula
Formulation
Stability
Arginine is a highly water-soluble solid. While a precise optimal pH range for 'ARGININE DNA' in cosmetic applications is not specified, Arginine generally influences protein solubility and thermal stability. Protein solubility has been observed to be higher at a lower pH (5.0-6.0), decreasing around pH 6.3 and stabilizing around pH 7.5 in the presence of arginine. At physiological pH, Arginine exists as a cation. It also aids in protein refolding, solubilization, and aggregation suppression within formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has affirmed the safety of alpha-amino acids, including Arginine, for cosmetic use up to an 18% concentration. L-Arginine is also recognized as Generally Recognized As Safe (GRAS) by the U.S. FDA for use as a nutrient supplement and food additive. No adverse effects have been reported for the topical cosmetic application of arginine, indicating high tolerability, even for sensitive skin types.
