non-nano zinc oxide
Why we use Zinc Oxide (Pharmaceutical-Grade, Non-Nano)
Origin: Ethically sourced mineral | Particle Size: Non-nano (larger than 100 nm) | Grade: USP (United States Pharmacopeia)
Non-nano zinc oxide is the powerhouse behind Summer Butter’s broad-spectrum sun protection. We chose it because it’s one of the safest, most effective ways to block harmful UVA and UVB rays—without absorbing into your skin or damaging the ocean.
✺ Mineral Shield, Not Chemical Filter
Zinc oxide works by sitting on the skin’s surface and physically deflecting UV rays, unlike chemical sunscreens that absorb into your bloodstream. Because we use non-nano particles, they are too large to penetrate the skin, making our formula safe for babies, sensitive skin, and daily use.
✺ Broad-Spectrum, Reef-Safe Protection
Zinc oxide is the only FDA-approved sunscreen ingredient that offers true broad-spectrum protection on its own—blocking both UVA (aging) and UVB (burning) rays. It’s also reef-safe, meaning it won’t harm coral reefs, marine life, or disrupt aquatic ecosystems.
✺ Skin Health Hero
Zinc is an essential trace mineral for skin health. It supports collagen formation, wound healing, and the creation of new skin cells. When applied topically, it helps soothe irritated skin, reduce inflammation, and even combat breakouts. Its natural antimicrobial properties make it perfect for acne-prone or sensitive skin types.
✺ Pure, Tested & Pharmaceutical-Grade
Our non-nano zinc oxide is pharmaceutical grade and tested to be free of heavy metals and toxins. It’s a clean, stable, and natural alternative to conventional sunscreen actives—and a crucial part of making Summer Butter both effective and safe.
✺ Gentle Enough for Every Body
Whether you’re a surfer, toddler, or tattoo lover, zinc oxide provides physical protection without irritation. It’s hypoallergenic, non-comedogenic, and blends beautifully with the nourishing oils and butters in our formula—leaving a soft, natural finish with every application.
