Regional differences in adhesive tape stripping of human skin.

摘要

The regional differences in acrylic adhesive tape stripping of human skin were evaluated. Two kinds of adhesive tape with different water vapor permeabilities were applied to the flexor side of the forearm and the cheek, palm and sole in eight healthy male volunteers. Dermal peeling force was measured at 1 and 6 h after application. Simultaneously, the electrical conductance of the skin beneath the applied tape and the amount of stripped corneocytes on the removed tape were measured. The regional difference in dermal peeling force of the permeable tape was large and that of the occlusive tape was small. The dermal peeling force of the permeable tape was high in the order of the palm, sole, cheek and forearm and individual differences among subjects in dermal peeling force of tape applied to the palm was large. The regional difference in dermal peeling force was considered to be related to fluid accumulation beneath the applied tape and the amount of stripped corneocytes. On the other hand, that the dermal peeling force of the occlusive tape was low and the regional difference was small may have been caused by fluid accumulation from the skin beneath the applied tape on all regions.
