For faster and better healing the wound should be kept moist and you can keep the wound moist by applying some Petroleum Jelly to the wound.
Applying the petroleum Jelly to the wound will keep the wound from drying out and prevent deeper scars from appearing on your skin.
Scabs are okay and help protect the wound from infection but when you apply petroleum jelly to the wound it will prevent a scab from forming which will make the wound heal much faster and the petroleum jelly will also protect the wound from infection like the scab would.
