Do cuts heal faster when covered?

Answer 1

Yes and no. In order for a cut to heal fast and with minimal scarring, a certain amount of moisture is needed (the the wound bed itself). If the cut is not covered there is more of a chance of pulling that can lead to pain and scarring. When using a cover, such as a band-aid, moisture will be locked in and the cut may heal bit faster. However, moist environments are a breeding ground for bacteria. Moisture can also lead to the healthy skin becoming soft, swollen, and wrinkled (like when you stay in a bath too long). This is called hyperhydration or maceration. Although maceration usually clears up after exposure to air, it can lead to increased sensitivity, infection, and in extreme cases more injury (since this skin is more susceptible to injury from rubbing or friction.

That is why, I would recommend keeping a wound covered when their is potential exposure to dirt, etc. But keeping it uncovered or lightly covered at other times. It is also important to replace wet bandages and dry the area thoroughly before recovering.
