What is coated titanium dioxide?
Titanium Dioxide is a physical mineral sunscreen filter that reflects and scatters UV rays. In its uncoated form, TiO₂ can generate ROS when exposed to UV light.
PFor this reason, dermatological sunscreens use coated Titanium Dioxide, meaning the particles are encapsulated with protective layers (silica, alumina, stearates) that:
- they block photocatalysis
- increase stability
- improve skin tolerability
It is one of the safest and most studied filters in the world.
How it works on the skin
- Immediate UVB protection
TiO₂ reflects and scatters UVB rays responsible for erythema and sunburn. - UVA II protection
Covers the 320–340 nm range, essential for preventing photoaging. - Zero photocatalysis (thanks to the coating)
The coating prevents ROS formation, making it safe even for reactive skin. - No skin penetration
Non‑nano particles remain on the skin surface and do not enter the dermis.
