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

  1. 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.
  2. Immediate protection
    As a physical filter, it works instantly — no activation time needed.
  3. Zero skin penetration
    Non‑nano coated ZnO stays on the skin surface and does not enter living tissue.
  4. Reduced whitening effect
    The coating improves optical dispersion, making the formula more transparent on the skin.
  5. Anti‑inflammatory properties
    ZnO naturally soothes the skin, making it ideal for sensitive and reactive skin types.
