Contraindications, Usage Precautions
Zinc oxide is a safe UV filter, very gentle on the skin, it does not cause irritation or sensitisation, and is non-photoallergenic. In some skincare products, it can be of nanometric size (ranging between 1 and 100 nm).
However, in this state, it is alleged to penetrate the skin barrier and accumulate in the body, where it is suspected to be toxic and carcinogenic. Similarly, it is advised against applying zinc oxide in nanoparticle form to damaged skin.
Finally, it is advised not to use zinc oxide near a ventilation source, as it has been demonstrated that inhaling zinc oxide can cause lung inflammation. This is also the reason why since 2018 it has been banned in sprays.
