Oligopeptide-34

Depigmenting oligopeptide for melanin inhibition and brightening

Oligopeptide-34 (CG-TGP2) is a depigmenting oligopeptide that inhibits melanin biosynthesis pathways, providing skin brightening and tone-uniformity benefits. Its sequence incorporates the RGD cell-adhesion motif alongside melanogenesis-inhibiting elements, targeting pigment production at the cellular level. The peptide is designed as a targeted active for brightening formulations.

Main characteristics

Oligopeptide-34 provides brightening via a sequence-specific mechanism rather than broad enzymatic inhibition, offering greater selectivity. Its RGD-adjacent structure may also contribute to cell-receptor interactions that support skin tone regulation. Suitable for combination with Nonapeptide-1 and Decapeptide-12 in multi-target depigmenting systems. Stable in aqueous formulations at pH 5.0–7.0. Produced via SPPS to ≥95% purity (HPLC + MS).

Applications

Brightening serums and spot correction treatments
Anti-hyperpigmentation formulations
Multi-target depigmenting systems in combination with Nonapeptide-1
Skin tone uniformity products
Research in peptide-based melanogenesis inhibition
