What is coated Zinc Oxide?
Zinc Oxide is a physical mineral sunscreen filter known for its true broad‑spectrum protection, covering UVB, UVA II, and even deep UVA I wavelengths.
In its raw form, ZnO can be slightly reactive under UV light.
So modern dermatological sunscreens use coated Zinc Oxide, where each particle is encapsulated with a protective layer (silica, alumina, stearates).
- prevents photocatalytic reactions
- increases stability
- improves skin comfort
- reduces whitening on the skin
Coated ZnO is considered one of the safest and most effective UV filters in the world.
How it works on the skin
- Broad‑spectrum UV protection
ZnO is the only mineral filter that naturally covers UVB + UVA II + UVA I, making it essential for anti‑aging SPF. - Immediate protection
As a physical filter, it works instantly — no activation time needed. - Zero skin penetration
Non‑nano coated ZnO stays on the skin surface and does not enter living tissue. - Reduced whitening effect
The coating improves optical dispersion, making the formula more transparent on the skin. - Anti‑inflammatory properties
ZnO naturally soothes the skin, making it ideal for sensitive and reactive skin types.
