Zinc PCA sits in the sebum control category, but the reason it works is specific. Zinc chelated with PCA; inhibits 5-alpha reductase (controls sebum); antimicrobial; zinc ions anti-inflammatory.
The scientific name is Zinc PCA. Zinc chelated with PCA; inhibits 5-alpha reductase (controls sebum); antimicrobial; zinc ions anti-inflammatory. This mechanism is consistent across properly formulated products, which means the real variable is concentration and delivery system.
Typical working concentration is 0.1–1%. Best suited to oily, acne-prone skin. Primary applications: sebum regulation, anti-acne, anti-inflammatory, microbiome balance.
Works well with: Niacinamide, salicylic acid.
