Product 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.
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. Tetrapeptide-30 (PKEK) is highly hydrophilic and has good skin penetration in microemulsion. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
