Zinc PCA

Zinc PCA is the zinc salt of pyrrolidone carboxylic acid (PCA), an active ingredient derived from an amino acid that introduces zinc into a formulation in water-soluble form. It is added to products for oily and problem-prone skin and to hair care for hair prone to oiliness, where it helps regulate sebum production and leaves a fresh sensation on the skin. PCA itself belongs to the natural moisturising factor (NMF) of the skin, so the zinc here is bound to a component naturally present in the skin. The ingredient holds ECOCERT certification, contains no animal-derived components or preservatives, and has not been tested on animals. It is processed in the water phase at temperatures up to 40 °C , making it easy to incorporate into toners, serums, creams, shampoos and deodorants without any complex procedure.

On the face, this manifests as less shine and a fresher feel. Antimicrobial effect – the manufacturer reports minimum inhibitory concentrations against a range of bacteria, yeasts and moulds, including the bacterium associated with acne (Cutibacterium acnes), Staphylococcus aureus and the yeast Malassezia furfur. In a finished product it acts as a supporting active ingredient and does not replace a preservative system. Astringent effect – the skin feels more tightened after application and pores appear visually smaller, which is especially apprecia
