Zinc Oxide
Uses of Zinc Oxide
The main use of Zinc Oxide is as a skin protectant in various topical formulations like creams, ointments, and pastes. It belongs to the class of medicines known as dermatological agents.
Additionally, it is also used in the prevention and management of diaper rash, as a sunscreen agent that provides broad-spectrum protection against both UVA and UVB rays, for the relief of minor skin irritations such as cuts, scrapes, burns, and insect bites, and in some acne medications due to its ability to reduce sebum production and mild antimicrobial properties.

How Zinc Oxide works
Zinc Oxide is a skin protectant and dermatological agent.
When applied to the skin, it forms a physical barrier that shields the skin from irritants, moisture, and UV radiation. This protection prevents direct contact with factors that can cause skin damage or irritation. Zinc Oxide particles scatter and absorb UVA and UVB rays, providing broad-spectrum protection against sunburn and premature skin ageing. It also has mild anti-inflammatory properties which help to soothe redness, swelling, and irritation associated with various skin conditions. Crucially, Zinc Oxide aids in wound healing by promoting collagen synthesis, cell proliferation, and immune function. This supports the skin's natural healing process when dealing with minor cuts, scrapes, burns, or insect bites.
