Oligopeptide-68 is a skin-whitening peptide raw material, a twelve-amino acid-rich oligopeptide commonly used for skin whitening, brightening, and acne treatment. It works by inhibiting melanocyte-stimulating hormone (MSH), reducing melanin production, and preventing excessive melanin formation. Its unique mechanism lies in Oligopeptide-68 mimicking the binding of TGF-β to receptors on the cell surface, utilizing the suppression of intramolecular channels of MITF to reduce induced and hereditary pigmentation, thus achieving a skin-whitening and brightening effect. It reduces the number of molecules related to melanin production, suppressing tyrosinase activity and melanin synthesis.

Inhibition of melanocyte-stimulating hormone (MSH): Oligopeptide-68 inhibits the activity of MSH, thereby reducing melanin production and preventing excessive melanin production.
Mimetic TGF-β receptor binding: Oligopeptide-68 mimics the binding of transforming growth factor β (TGF-β) to receptors on the cell surface, inhibiting the intramolecular channel of MITF (micro-eye-associated transcription factor) through this pathway, thus reducing induced and hereditary pigmentation and achieving skin whitening and brightening effects.
Reduction of melanin formation-related molecules: Oligopeptide-68 reduces the number of molecules related to melanin formation, such as MITF, TRP-1, TRP-2, and tyrosinase, thereby inhibiting tyrosinase activity and melanin synthesis.
Highly effective: At the same concentration, Oligopeptide-68 exhibits stronger activity than other traditional whitening ingredients (such as vitamin C and arbutin).
Due to its significant whitening effect, oligopeptide-68 is widely used in cosmetics such as brightening creams, brightening foundations, pressed powders, and spot-removing creams (such as for sun spots and freckles).

For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
