What Is Zinc Oxide, Anyway?

Zinc oxide is a mineral UV filter that sits on top of the skin and reflects UV rays, unlike chemical (organic filter) sunscreens, which absorb into the skin. It’s the only sunscreen filter approved by both the FDA and Health Canada for broad-spectrum UVA and UVB protection.

Why We Chose Non-Nano Zinc

At Glow Jar Beauty, we chose non-nano zinc oxide (20%) because:

1. It’s Safer for Sensitive Skin

Non-nano zinc sits on top of the skin, where it forms a reliable, physical UV shield. It’s less likely to cause irritation or oxidative stress, which is especially important for those with rosacea, eczema, or compromised skin barriers.

2. It’s Environmentally Safer

Non-nano zinc is considered lake/reef-safe, especially when it’s uncoated or non-soluble. Many chemical filters and nano metals have been shown to harm coral and aquatic life. 

3. It Offers Broad-Spectrum, Stable Protection

Zinc oxide is photostable, meaning it doesn’t degrade in sunlight like some chemical filters. Non-nano particles provide excellent UVA protection, which helps prevent long-term damage like pigmentation and premature aging.

4. We’ve Designed Our Formula to Minimize White Cast, Without Going Nano

Using ingredients like polyhydroxystearic acid, iron oxides, and lightweight skin-loving esters, we’ve created a smooth finish without compromising on safety or performance.

The Bottom Line

When it comes to sunscreen, particle size isn’t just a science conversation, it’s a safety one.

At Glow Jar Beauty, we’ve chosen non-nano zinc because it aligns with our values:

• Safe for sensitive skin

• Minimal environmental impact

• High-performance UV protection

• Full ingredient transparency

• It Won’t Enter the Bloodstream

Our goal isn’t just to protect your skin, it’s to empower you with the knowledge to make informed choices.
