Zinc PCA
Generally safe·Limited evidence
Zinc PCA is a zinc salt of a naturally occurring skin humectant, used mainly to help regulate oil and support a balanced skin microbiome in oily or acne-prone formulas. It has a long history of use with no significant reported irritation, though dedicated cosmetic-specific review data is thinner than for more common ingredients.
