DuoDerm Signal Hydrocolloid Dressing, Sterile, 4" x 4"

The DuoDerm Signal Hydrocolloid Dressing from ConvaTec is designed to support a moist wound healing environment while protecting the wound bed from outside contaminants. Featuring a CGF (Controlled Gel Formation) hydrocolloid matrix paired with a flexible foam backing, this 4 x 4 inch (10 x 10 cm) dressing conforms comfortably to the body and stays in place during daily activities.

Both the adhesive hydrocolloid layer and the outer film are permeable to moisture vapor, allowing the skin to breathe while the dressing manages wound exudate. At the same time, the dressing forms an occlusive barrier that helps keep bacteria, viruses, dirt, and water away from the wound site, reducing the risk of outside contamination during the healing process.

This hydrocolloid dressing is a practical choice for clinicians and caregivers managing a variety of wound types where a self-adhesive, protective covering is needed. Its square shape and moderate size make it easy to apply to many body areas, and its dual-purpose barrier and moisture-management properties help support consistent, uninterrupted wound care.
