Most minor burns will heal best covered. Bandaging a burn keeps air and debris from irritating the area, and gives a layer of protection to blistered skin. It’s ideal to use a sterile gauze bandage wrapped loosely, rather than a fluffy material that may get stuck to wounds and cause infection.
If burned skin is blistered, the blisters should not be popped, as broken skin is more likely to lead to issues with healing. Instead, gently apply a soothing ointment such as Waxelene to the blister and surrounding skin and keep loosely covered with a bandage. This ensures that the wound will be protected but still have adequate air circulation to assist with the healing process.
