Description

Tetrapeptide-30 is a skin-brightening peptide consisting of four amino acids. Tetrapeptide-30 can act as a tyrosinase inhibitor, lightening hyperpigmentation and evening out skin tone by reducing the amount of tyrosinase and inhibiting melanocyte activation[1].

In Vitro

Tetrapeptide-30 (0-10 μg/mL, 24 h) can effectively reduce UVB-induced gene expression of IL-6, TNF-α and POMC (proopiomelanocorticotropin), and also decreased IL-8 gene expression in a dose-dependent manner[1].
Tetrapeptide-30 (PKEK) is highly hydrophilic and has good skin penetration in microemulsion[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
