Zinc salt used to support oil balance and skin conditioning, especially in blemish-prone formulas.
Zinc PCA combines zinc with PCA, a component related to the skin’s natural moisturizing factor. It is commonly used in oily or blemish-prone formulas because it can support sebum balance while also contributing skin-conditioning benefits. It is not a direct exfoliant, so it can complement acids rather than duplicate their role.
Usage & cautions
Can feel drying in some formulas; balance with moisturizer if needed.
