Zinc pyrithione for skin

Table of Contents

Zinc is an essential mineral named after the German word for "tooth-like" or "pointed" — and has some real bite when it comes to fighting acne-causing fungus and bacteria. Zinc is a key ingredient in the U.S. penny and most multivitamins. It's also used in zinc pyrithione-based acne care with powerful antimicrobial and antifungal action. But be warned — not all topical forms of zinc effectively treat acne. Be sure to look for zinc pyrithione, and not zinc oxide (which is great in your sunscreen, but does not fight acne!).

How does zinc pyrithione work?

Your skin is a party of microorganisms. Everyone’s having a good time until party-crashing microorganisms start multiplying and trashing your pores. P. acnes bacteria are common offenders, as are Pityrosporum, a fungus with a fondness for oily pores. When Pityrosporum sets up camp, it can cause small uniform bumps, most commonly on the jaw, forehead, and hairline. Pityrosporum especially loves increased humidity and sweat, so if these conditions make your acne worse, it may be a culprit. Zinc pyrithione works by blocking the multiplication of unwanted bacteria and fungi like Pityrosporum — going straight to a root cause of acne for many people. It also has anti-inflammatory properties, reducing irritation and redness that further aggravate acne.
