Compeed hydrocolloid technology is an active gel with moisture absorbing particles. Specially designed to fit the ball of the foot, Compeed plaster acts like a second skin to support the natural moisture balance. It relieves blister pain instantly, protects against rubbing with its thicker cushioning zone, and offers fast wound healing. The plaster stays in place for several days. Clean and dry skin before use. Do not touch the adhesive side of the plaster. Leave in place until it starts to detach, which may be up to several days. Diabetics should consult a doctor before use. Full instructions and warnings are inside.
