What They Say

“Optimal for sensitive or traumatized skin and safe for children, Physical UV Defense is a true broad-spectrum UVA/UVB sunscreen perfect for daily use. This cosmetically elegant, all-physical sunscreen contains 5% transparent zinc oxide and 10% titanium dioxide, two non-irritating active ingredients ideal for use on all skin types. Breakthrough dispersion technology minimizes the ?whitening? effect commonly found in other all-physical sunscreens by equally distributing reduced sunscreen particles.”

“Our sunscreens provide true broad-spectrum UVA/UVB protection. This revolutionary line contains Z-Cote®, transparent zinc oxide, which protects skin from the damaging UVA rays proven to be responsible for premature signs of aging.”

“Many sunscreens contain nanoparticles of zinc oxide or titanium dioxide, even though you probably won’t see the term ‘nano’ on the labels.”

“Nanoparticles of the two compounds are used in sunscreens because the normally white substances, which absorb ultraviolet radiation, become more transparent when the particles are nano-sized. We asked an outside lab to test for those nanoparticles in eight sunscreens that listed either compound on their labels. All contained the particles, yet only one, Keys Solar RX, disclosed that use of nanotechnology.”
