Take a zinc supplement

Zinc is a crucial vitamin for immune system health, hormone production, cell development, and metabolism. According to a meta-analysis from 2020, those who received zinc treatment saw a noticeable improvement in the number of inflammatory lesions compared to those who did not.

The safe upper limit for daily zinc intake is 40 milligrams, so it's usually advisable to stay within that level unless you're under a doctor's care. Taking too much zinc might have negative consequences, such as gastrointestinal discomfort. It's also important to remember that there is no evidence to support the effectiveness of applying zinc to the skin. This could be a result of zinc's poor skin absorption.
