Yes! We take the appropriate caution to ensure we do not use nanoparticles in any form that can be inhaled or ingested.
Titanium Dioxide and Zinc Oxide are two of the most common and effective active sunscreen ingredients that create a physical block on the skin. Much of the concern surrounding these ingredients is when these ingredients are micronized into nano-particles, and they may risk becoming inhaled or ingested.
At Bare Republic, we take the appropriate caution to ensure we do not use nanoparticles in any form that can be inhaled or ingested (i.e., sprays, lips, baby products, etc.). That said, we choose to formulate our Mineral Face SPF 30 Sunscreen Lotions with nanoparticles, as it allows our customers to achieve a transparent and smooth application. As noted by the EWG, nanoparticles, when applied as a lotion, do not penetrate the skin. The form in which nanoparticles have shown in wide-ranging studies to be a danger is as an airborne substance or any form that can be inhaled or ingested: loose mineral makeup powder, sprays, lip products, etc.
