All wounds should be covered with a dressing to protect it from germs that could cause infection. We recommend using a gauze dressing that is moistened with AMERIGEL Wound Wash to cover the wound after applying AMERIGEL Hydrogel Wound Dressing. This also helps promote a moist wound bed which, according to the Agency for Healthcare Research and Quality (AHRQ), is the optimal environment for healing to take place. Wounds left open to the air will dry out and often times form a scab. In chronic, non-healing wounds, scabs can delay the healing process and, in many instances, the scab may need to be surgically removed by a healthcare provider so that healing continues.
