Zinc PCA: What makes it different from other zinc compounds?
On one serum it says Zinc PCA , on another skincare product it says Zinc Oxide – the common beginning doesn’t tell the whole story. Zinc PCA is the zinc salt of pyrrolidonecarboxylic acid. The ingredient database COSMILE Europe classifies it as moisturizing and skin-caring. Zinc oxide is another compound that is used, among other things, as a UV filter. Sun protection cannot therefore be derived from Zinc PCA in the ingredient list.
In the Anua Azelaic Acid 10 Hyaluron Redness Soothing Serum you will find Zinc PCA next to azelaic acid. When trying it out, the instructions for the entire serum count. It would be too short-sighted to attribute its properties solely to zinc PCA or to use it like a pure zinc skincare product.
