“A sebum-regulating zinc salt that tackles oiliness and acne without drying the skin.”
What it does
Zinc PCA is the zinc salt of pyrrolidone carboxylic acid (PCA), a natural moisturising factor found in skin. It combines the sebum-regulating, anti-androgenic, and antibacterial properties of zinc with the humectant and skin-identical benefits of PCA. It reduces 5-alpha reductase activity (an enzyme involved in sebum production), making it notably effective for oily skin management without the drying effects of zinc alone.
Benefits
- Regulates sebum production and reduces shine
- Inhibits 5-alpha reductase to address hormonal drivers of oiliness
- Antibacterial action against acne-causing bacteria
- Maintains hydration levels through PCA's humectant properties
- Reduces acne and blackhead formation
