In 2019, the FDA ruled that para-aminobenzoic acid (PABA) was no longer recognized as safe and effective for use in sunscreens, making the 'paba free' label a critical indicator of a modern and safer formula. This shift reflects decades of dermatological concerns over its side effects.

According to the product review site SkinSAFE, Coppertone Pure and Simple is free of added gluten and other wheat-related ingredients. This is crucial for individuals with celiac disease or gluten sensitivities, who must consider even topical products like Coppertone Pure and Simple for gluten content.

Research has confirmed that a very small proportion of zinc is absorbed topically, primarily as zinc ions, rather than as larger nanoparticles. This minimal dermal absorption is crucial for understanding how topical zinc provides localized benefits to the skin, such as anti-inflammatory and wound-healing effects.

Approximately 6% of the body's total zinc content is concentrated in the skin, a fact that highlights its importance for dermal health. The benefits of wearing zinc, whether applied topically or incorporated into textiles, span from powerful UV defense to enhanced antimicrobial and healing properties.

While zinc oxide exists naturally as the rare mineral zincite, most of the world's supply is produced synthetically due to its widespread use in products like cosmetics and ointments. This guide explains the distinction and demonstrates how to get zinc oxide naturally for your diet and safely formulate homemade skin products with commercially processed powder.

According to the U.S. Food and Drug Administration (FDA), zinc oxide may be safely used in cosmetics and as an active ingredient in sunscreens and skin protectants at concentrations up to 25 percent. This white, powdery mineral has different safety considerations depending on its use and form, from common topical applications to significant industrial exposure.
