Science
Mechanism of Action
This peptide is understood to signal the skin, thereby activating its endogenous repair processes. This action is believed to stimulate the biosynthesis of crucial extracellular matrix components, including collagen, elastin, and fibronectin. By enhancing the synthesis of these structural proteins, the peptide aims to mitigate visible signs of skin aging, augment skin firmness and elasticity, and contribute to the restoration of the skin barrier function.

Stability
Specific optimal pH for stability is not detailed. Generally, peptide solubility is pH-dependent; acidic peptides typically dissolve better in 10% ammonium bicarbonate, while basic peptides may prefer 10% acetic acid. For peptides with very low aqueous solubility, initial dissolution in organic solvents (e.g., DMSO, isopropanol) followed by gradual water addition may be necessary.
Safety
Safety Profile
No specific safety assessment from regulatory bodies such as CIR, SCCS, or FDA has been found for R-(ASPARTYL OLIGOPEPTIDE-162 ASPARTYL RH-POLYPEPTIDE-48). Information on complex recombinant peptides of this nature is limited; some databases indicate similar INCI names are not used in cosmetic products, while others list them as cosmetic ingredients without comprehensive safety data.

Verdict
While general peptide mechanisms suggest promising skin benefits, the absence of specific clinical studies and comprehensive safety evaluations for this particular complex peptide, alongside unknown irritancy and comedogenicity, leads to an insufficient-data verdict for definitive assessment.
