GreyReverse™ (Palmitoyl Tetrapeptide-20) and Skin Color

GreyReverse™ (Palmitoyl Tetrapeptide-20) is a peptide specifically designed to stimulate hair pigmentation. Its primary function is to help reduce the appearance of grey or white hair by promoting melanin production in hair follicles.

Based on the product information, GreyReverse™ is intended for use in hair care products, such as hairsprays, to address hair greying. There is no indication that it affects skin pigmentation or causes skin darkening.

Therefore, GreyReverse™ is not expected to darken skin color.
