Palmitoyl Dipeptide-10

Palmitoyl Dipeptide-10 is a palmitoylated signaling peptide used in low concentrations (typically well under 1%) for anti-aging/skin-conditioning and is generally well tolerated in clinical and post-market experience. As a non-acidic, non-volatile peptide without inherent surfactant or exfoliating activity, it has a low rate of irritant reactions, though very reactive/eczema-prone patients can still experience occasional stinging or dermatitis from peptide products or the overall formula. Given the vulnerable-population focus, it fits best as very gentle rather than exceptionally gentle/inert. Safety Notes: In commercial leave-on products (eye creams, anti-aging serums, moisturizers), Palmitoyl Dipeptide-10 is most often used as part of peptide blends, with effective in-formula levels commonly landing in the low-ppm range; the lowest marketed uses are typically around 0.0005% when included as a supporting peptide in multi-peptide complexes. High-strength consumer serums and targeted treatment products that feature the peptide more prominently can reach ~0.05% as an upper observed market level before cost and solubility/handling constraints become limiting. Rinse-off products rarely use it at meaningful levels due to wash-off dilution, so the practical market range is driven primarily by leave-on formulations.
