DermaRite DermaCol Collagen Dressing is an advanced wound care dressing made of collagen, sodium alginate, carboxyl methylcellulose and ethylenediamine-tetraacetic acid (EDTA). It transforms into a soft gel sheet when in contact with wound exudates and maintains a moist wound environment, and creates ideal conditions for healing. It may be trimmed and layered for management of deep wounds.
