We have heard that it is good to apply Vaseline to a wound, as it helps it heal faster. But, now, a report presented by specialists of the University of Leeds, in the United Kingdom, reveals that this treatment has increased the risk of the wound becoming infected.
The researchers studied the microscopic film that forms over wounds during the healing process. This film is formed by a protein called fibrin, and has pores small enough to pass air but not bacteria.
The problem, according to the authors of the study, is that by applying Vaseline that film is destroyed, which has the mission to act against barrier bacterial infections for about twelve hours. And in that way increases the danger of infection.
