ABSTRACT:
A dressing for preventing and treating blisters and for treating corns, calluses, warts, and other skin conditions. The dressing has a dressing layer covered by protective cover layer and a release sheet. The dressing has an adhesive composition on a skin-contacting surface. The dressing layer has a thick center portion surrounded by a flange portion. The thick portion has a thickness of less than 1.0 mm. and preferably a thickness of 0.5 mm. The flange portion has a thickness of 0.15 to 0.20 mm. and extends no more than 5.0 mm. from the edge of the thick portion. The configuration of the dressing layer, particularly when used with a hydrocolloid adhesive provides a dressing having wrinkle resistant edges allowing the dressing to be used in areas of the body having high mobility.
