DIPEPTIDE-16.

Valuable / SKIN CONDITIONING

DIPEPTIDE-16 is a potent biomimetic peptide engineered to address skin brightening, promote a youthful appearance, and offer photoprotection. It works by precisely interfering with melanin synthesis pathways and mitigating inflammation, making it a multifaceted active for comprehensive skin health.

Science

Mechanism of Action

Methyl Undecylenoyl Dipeptide-16, a modified derivative, precisely targets the Melanocortin 1 Receptor (MC1R). By competitively binding to MC1R and displacing its natural ligand, alpha-MSH, it effectively deactivates a cascade of melanogenic genes, including tyrosinase, TRP1, TRP2 (DCT), MITF, and POMC, thereby blocking melanin overproduction. Furthermore, it demonstrates an additional benefit by reducing UVB-induced inflammatory responses, contributing to a significant photoprotective effect.

Stability

Peptide stability is intrinsically pH-dependent; extreme pH environments (acidic pH 1-3 or alkaline pH > 7) can instigate degradation pathways such as hydrolysis or epimerization. A neutral to slightly acidic pH range is generally considered optimal for preserving peptide integrity. The specific optimal pH for DIPEPTIDE-16 is not precisely defined. Its 'Methyl Undecylenoyl' modification is a strategic enhancement, increasing lipophilicity to improve skin penetration and integrate well into various formulation types.
