Zinc oxide ointment is a topical formulation that contains zinc oxide as its active ingredient. It is commonly used for its protective, soothing, and healing properties. Here’s an overview of its key aspects:
Composition and Properties
- Active Ingredient: Zinc oxide, a white, odorless powder that has antimicrobial and astringent properties.
- Formulation: Typically combined with a base, such as petrolatum, lanolin, or other emollients, to create an ointment that is thick and occlusive, which helps to protect the skin and retain moisture.
Uses

- Irritation Relief: Alleviates symptoms associated with skin irritations, such as rashes resulting from exposure to irritants or allergens.
- Sun Protection: Exhibits physical UV-blocking capabilities, making it a common ingredient in sunscreen products.
- Acne Treatment: Sometimes used in formulations for acne due to its anti-inflammatory properties.
Mechanism of Action
Zinc oxide works by:
- Forming a protective barrier on the skin.
