Structure of ZINC PIDOLATE







Zinc Pidolate (Zinc PCA) is a topical skin product with purifying, astingent, anti-inflammatory, antiseptic activity. It has long been used as a cosmetic ingredient, because of its astringent and anti-microbial properties. Zinc Pidolate has also being shown to be effective against halitosis. Zinc PCA prevents the UV-induced MMP-1 production in vitro by suppressing the activation of AP-1. Zinc PCA was also able to enhance type I collagen synthesis in NHDFs, by increasing the expression of the mRNA encoding the ascorbic acid transporter SVCT2 in non-UV irradiated NHDFs, which suggests its promising effect against not only photoaged skin but also for the simple atrophic change of intrinsic skin ageing. Zinc PCA is able to suppress sebum secretion by inhibiting 5-α reductase in hyperseborrhea, to suppress body odor by forming zinc salts with short-chain fatty acids, to suppress wrinkles by inhibiting AP-1 to and inhibit bacterial growth including acne related Propionibacterium acnes.
