产品描述: | Tetrapeptide-30 是一种由四个氨基酸组成的亮肤肽,可充当酪氨酸酶抑制剂,通过减少酪氨酸酶的数量以及抑制黑色素细胞激活而淡化色素沉着,均匀肤色。 |
体外研究: |
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. |
