Wound dressings are materials applied to injuries to protect them from infection and promote healing. They come in various types, including adhesive bandages, gauze pads, and hydrocolloid dressings, each designed for specific wound types. Proper dressing helps maintain a moist environment, which can speed up the healing process. In addition to protection, wound dressings can absorb exudate, reduce pain, and minimize scarring. They are often used in medical settings, such as hospitals and clinics, and can also be found in home first aid kits. Choosing the right dressing is essential for effective wound care and recovery.
