Contraindications, Usage Precautions

Zinc oxide is a safe UV filter, very gentle on the skin, does not cause irritation or sensitization, 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 on damaged skin.

Finally, it is recommended 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 why since 2018 it has been banned in sprays.

Zinc oxide is a chemical molecule of oxygen and zinc. Widely used in cosmetology for its numerous benefits, this matte white powder is extracted from pure zinc ore. As early as the 19th century, it was used for its antibacterial properties. Today, its presence in nanoparticle form is the subject of controversy.
