Keeping wounds open may be a common practice, but in reality, it is detrimental to wound healing. There is plentiful research to back up the fact that wounds heal faster when they are protected with a wound plaster. Moreover, even minor wounds are prone to infections when left open. Covering your wound prevents the entry of bacteria and greatly reduces the risk of infection. It also minimizes scarring. Hence, it is always wise to cover your wounds using Hansaplast bandages.
