Keeping a wound lightly moist and covered is generally better than letting it dry out for clean, minor cuts, scrapes, and shallow wounds. Moisture supports cell movement and can reduce scabbing, pain, and scarring. However, it is not the right approach for wounds that are dirty, deep, heavily draining, or showing signs of infection, or for people with diabetes, poor circulation, or weakened immunity. The best choice depends on wound type, location, and your overall health, so seek professional advice for anything beyond a simple minor injury.
