What is a micronized zinc oxide?

zinc oxide is an inorganic compound used in a wide range of products and is a common component in sunbathing. Mikronized zinc oxide is a zinc oxide that has been treated to reduce the average size of its particles and produce ultra -black powder. The micronized term can refer to particles that are micro size, which means they are a diameter of several micrometers (1 micrometer is one million meter), but can also refer to much smaller nanoparticles, which means particles that have 1-100 nanometers in diameter (1 nanometer is one billion meter). Different terms such as ultrafine, nanosized and micronized can be used to describe this kind of zinc oxide. Scientific studies have shown that both micronized zinc oxide and common zinc oxide offer very effective protection from the sun, prevent harmful UVA and UVB rays in sunlight in achieving skin.rritation and effective sunscreen. However, a regular zinc oxide may leave at the application toskin white film. Products containing micronized zinc oxide do not leave this film and offer a form of invisible zinc oxide protection, because the particles are too small to see the naked eye. Regular and micronized zinc oxide acts as physical barriers against sunlight, reflecting it before it reaches the skin.

Concerns that micronized zinc oxide could enter the body through the skin, especially if it contains nanosized particles and that this could cause health problems. Many commonly available sunscreen and sunscreen contain zinc oxide particles that have a diameter of 30-200 nanometers, which means that many such products contain nanoparticles. Most scientific studies show that while micronized zinc oxide can penetrate into the farthest layer of the skin, it is not a penent into living tissue or into the bloodstreamis a risk to human health.

Some studies suggest that micronized zinc oxide may be a problem if it is inhaled and gets into the lungs, rather than applied to the skin. Small size micronized particles means that if inhaled, they could settle deep inside the lungs and cause potential health problems. Some experts recommend that you should not use powdered or spraying creams or sunscreen containing ultra -fine zinc oxide particles. Products such as lotions and creams are considered safer because their consistency is unlikely.
