To reduce the opaque appearance of zinc oxide, many sunscreen companies are making the particle smaller through a process referred to as “micronizing” to produce nanosized zinc particles. The efficacy and cosmetic nuisance are due to the size of the zinc particle. It’s thick white appearance is what makes it so effective, but also not a popular choice when selecting between different sunscreens. Zinc oxide is classically associated with the pasty white lifeguard nose. While it is an effective physical sun blocker, it does have some cosmetic drawbacks. Zinc oxide is a common ingredient found in many sunscreens that are effective in blocking ultraviolet A (UVA) rays. When shopping for a sunscreen, it is not only important to know what ingredients are safe and effective in combating the sun’s harmful rays, but it is also important to understand what terms like “micronized,” “nanosized,” and “nanoparticles” refer to when it comes to your sunscreen. But can these tiny particles be harmful to our body? However, new nanotechnology has revolutionized the opaque appearance of zinc oxide by refining the zinc particles to make them smaller. Until recently, zinc oxide sunscreen formulations appeared as a thick, white paste on the skin. Of the two, physical barriers work by reflecting or scattering the UV rays away from the skin.
There are two types of sunscreens, chemical and physical barriers.
NON NANO ZINC OXIDE SUNSCREEN SKIN
Sunscreens also prevent premature aging and skin cancer. Sunscreens are one of the most effective methods to protect the skin from the sun’s harmful rays.
