Lademann et al. [8] could not detect any absorption of

micronized TiO 2 particles (crystal size approximately 17

nm) into the epidermis following repeated application of

an o/w emulsion to the forearms of volunteers over several

days; only the upper stratum corneum and hair follicles

showed any evidence of particle penetration. This

finding, and the recent work of Alvarez-Roman et al. [9] ,

suggests that the dermal penetration of TiO 2 microparticles

reported earlier by Tan et al. [10] were in fact associated

with hair follicle openings and not due to direct

diffusion through the layers of the epidermis. Dussert et

al. [11] used electron microscopy to show that there was

no evidence of penetration into human epidermis for

both TiO 2 and ZnO nanoparticles dispersed in a topically

applied o/w emulsion; however, the length of skin

exposure of the formulations in this study was not specified.

Although nanoparticles of physical sunscreens do not

appear to penetrate into the viable epidermis, there is potential

systemic exposure to nanoparticulate inorganic

sunscreens which may partially dissolve following topical

application [12] . The goal of the present study was to assess

the potential epidermal penetration and systemic exposure

of a novel ZnO nanoparticulate sunscreen formulation.

We determined both the location of ZnO particles

within the epidermis and the total amount of zinc penetrating

through epidermal membranes in vitro over a 24-

hour period after topical application of the ZnO nanoparticulate

sunscreen formulation
