Can too much moisture delay wound healing?

Moisture in the wound is essential for healing; however, excessive moisture is harmful. Normally, the fluid coming from the wound is very rich in protein-melting enzymes which help to remove dead tissue from the wound bed. Because these enzymes can melt protein, they can also melt the normal skin around the wound.
