Q: Should you keep cuts covered or let them breathe?
Oz Says: After you've washed out the cut with soap and water, slather on a little Vaseline or other emollient, and put a lid on it. Moisture helps it heal best, says Adam Friedman, MD, a dermatologist at George Washington School of Medicine and Health Sciences, because it allows cells to communicate with each other better. That's especially important in the first 24 to 48 hours, when your body sets up the initial highway for immune cells to rush in and new skin to form.
A scab (more likely to form when a cut's uncovered) interferes with this process, forcing cells to get around and under it. Got a scab anyway? Don't pick it or the healing has to start over again.
