Is your sunscreen safe to use?

We hear a lot about the harmful effects of UV rays so we protect ourselves with sunscreen. But is the sunscreen you’re using good for your health?

With so many options available, it can be difficult to know which sunscreen is the best choice for you and your family. One thing to consider when choosing a sunscreen is whether or not it contains nanoparticles.

PURU sunscreen only uses non-nano Zinc oxide so it does NOT contain Nanoparticles or nanotechnology.

But what are the risks and benefits of using nanoparticles like zinc oxide and titanium dioxide in sunscreens?

What Are Nanoparticles?

Nanoparticles are tiny particles that are measured in nanometers.

They are used in many sunscreens as the main active ingredient that protects your skin. Zinc oxide and titanium dioxide are the most common mineral sunblock ingredients and many commercial sunscreens use nanoparticles of these ingredients in in their mineral sunscreen formulations.

The most common chemical sunscreen active ingredients that use nanoparticles include avobenzone, oxybenzone, octisalate, octocrylene, homosalate and octinoxate. These ingredients are absorbed into the skin and work by absorbing UV rays and converting them into heat, which is then released from the skin. It’s important to note that while these ingredients are considered safe by the FDA, they have been shown to have negative effects on the environment and marine life when they wash off of the skin and into the water. This is why many experts are advocating for the use of mineral-based sunscreens that use non-nano zinc oxide as the active ingredient. These ingredients form a physical barrier on the skin that reflects UV rays, rather than absorbing them.


The EU has roughly defined non-nano as “the primary particle size is greater than 100nm,” and Australia defines non-nano as “more than 90% of particles are above 100nm.” This means that a non-nano sunscreen has particles that are larger than 100nm, which makes them less likely to be absorbed into the skin.

So, why take the risk of using nanoparticles in sunscreen?

With so much evidence suggesting that nanoparticles can be a potential danger to the skin, it’s important to choose a sunscreen that is safe for your health. This is why PURU has developed a natural sunscreen with only non-nano zinc oxide. PURU’s natural sunscreen is invisible on the skin, and you can safely enjoy the sun while feeling confident about the health of your skin.

PURU sunscreens only contain Non-Nano Zinc and other natural ingredients. This means that our sunscreen not only protects your skin from harmful UV rays, but it also protects oceans, rivers and lakes form nasty nano particle and toxic ingredients. 

In addition to being safe for your skin, PURU’s natural sunscreen is also eco-friendly. Our packaging is recyclable, and our sunscreens are mineral-based. This means that our sunscreens do not contain any harsh chemicals that can harm the environment.

When choosing a sunscreen, it’s important to consider not only the ingredients but also the brand’s commitment to safety and the environment. PURU is committed to providing natural, safe, and eco-friendly products that protect your skin.

In conclusion, when it comes to protecting your skin from harmful UV rays, it’s important to choose a sunscreen that is safe and effective.
