Tetrapeptide-30

Names

[ Name ]:
Tetrapeptide-30

Biological Activity

[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].
