Zinc PCABenefits, how to use & safety
A calm, quiet oil regulator.
What is Zinc PCA?
Zinc PCA combines zinc with PCA, a natural moisturising factor in skin. It is a gentle sebum regulator, often paired with niacinamide for oil control without drying skin out.
How it works
Zinc has mild antibacterial and anti-inflammatory activity and appears to moderate the enzyme involved in sebum production. PCA binds water, so skin feels balanced rather than stripped.
