Realistic Exposure Study Supports the Use of Zinc Oxide Nanoparticle Sunscreens

Caption

Multiphoton images of human skin at a depth of 15-20 μm below the skin surface in volunteers after application of uncoated and silicone-coated zinc oxide nanoparticles suspended in a commercial sunscreen base compared with no product (untreated control). Red and yellow pseudocolor indicates the presence of zinc oxide nanoparticles in skin furrows. The blue-green color shows autofluorescence from living epidermal cells, with no evidence of zinc oxide nanoparticle penetration.
