What This Ingredient Does

Zinc is an essential trace mineral involved in many biological processes, including immune function, inflammation control, and skin repair. In dermatology, it is particularly valued for its role in supporting acne-prone skin.

Topically, forms such as zinc PCA help regulate sebum production while providing mild antibacterial and anti-inflammatory benefits. This can help reduce excess oil and calm inflamed breakouts. Zinc is often used alongside ingredients such as niacinamide o support clearer, more balanced skin.

Orally, zinc plays a role in immune defense and skin healing. Adequate zinc levels also help regulate inflammatory responses in the body, which can influence acne severity and overall skin health.
