What it is

How it works
In a cosmetic product, Zinc Azelate Hydroxide works by gently reducing the activity of enzymes that produce excess sebum, while zinc helps calm inflammation and soothe irritated skin. It also has mild antimicrobial effects that can help maintain a balanced skin microbiome.

Cons and cautions
Milder effect
