DuoDERM Extra Thin Hydrocolloid Dressing is a hydrocolloid moisture-retentive wound dressing for superficial, lightly exuding wounds with little or no exudate and for early intervention on those at-risk for skin breakdown. It combines a unique ConvaTec hydrocolloid formulation that distinguishes it from other hydrocolloid dressings and a vapor-permeable outer film to provide an occlusive moist environment.
