It is considered an effective barrier essential to the protection of the internal milieu from the external environment; however, there are several reports of particle penetration into the stratum corneum and hair follicles, and a report of increased titanium in the epidermis and dermis following the application of sunscreens containing titanium dioxide (Lademann et al.
Specifically, we hypothesized that fine particles are able to penetrate the stratum corneum and reach the immunologically active epidermis, and that flexing motion, as at the wrist, provides the kinetic energy necessary to move particles into the skin.
Integrity of the stratum corneum was verified immediately before each experiment using the NOVA Dermaphase Meter, model 9008 (NOVA Technology Corp.
Removal of 6-7 [micro]M of the stratum corneum by 30 tape strips using D-Squame tape and significant increases in transepidermal water loss after 30 tape strips have been documented (Dreher et al.
One-micrometer red fluorospheres are clearly visible in the stratum corneum and epidermis after the 30-min application of beads and flexing motion (blue arrows, Figure 2A), and in the stratum corneum, epidermis, and dermis at 60 min (all arrows, Figure 2B).
