High-quality Oligopeptide-68 for skincare ingredients applications. Direct sourcing from reliable manufacturer. Wholesale supply available worldwide.

Product Description

Oligopeptide-68 is a synthetic biomimetic peptide, typically composed of 10 amino acid residues (Arg-Asp-Gly-Gln-Ile-Leu-Ser-Thr-Trp-Tyr). It is designed as a skin-brightening and pigmentation-regulating active. Oligopeptide-68 works by modulating melanogenesis signaling—particularly inhibiting MITF (microphthalmia-associated transcription factor) pathways and reducing tyrosinase activity—to slow down melanin synthesis, thus helping fade hyperpigmentation, melasma, and dark spots. It is formulated for water-based cosmetic systems and is used in brightening serums, spot treatments, and anti-pigment formulations. Its advantages include targeted pigment modulation, good formulation compatibility, and relatively low irritation potential at proper doses. The peptide offers formulators a bioactive option for achieving more even skin tone and reducing discoloration in premium whitening or corrective skincare products.
