eritrean, you are seriously making me mad. you are coming off like you know what to do and are telling people what to do even though it is very wrong. you say let the scab dry out dont touch water or anything to it. stop lying to people and stop sounding like you are telling facts. you dont know what you are talking about. Surface drying not only impedes delivery of nutrients and immune defenses to the wound surface but also markedly impedes the ability of cells to migrate across the wound surface. Epithelial cells need a moisture layer to migrate and spread. For any re-epithelialization to occur on a dry surface, the cells must burrow beneath the "scab" using a controlled release of proteases Moist healing speeds up the healing process. Tissue regrowth is slowed if a wound dries.
Moist healing results in less scarring. A scab (dried serum) is the bodys natural attempt to keep a wound moist.
