Vaseline is often recommended as a home remedy for minor burns, but there is no scientific evidence to support this claim. Some people believe that Vaseline creates a barrier between the skin and the air, which can help to speed up the healing process. However, this is not supported by any scientific evidence.
In fact, Vaseline may actually slow down the healing process by trapping heat and preventing the wound from drying out. It is important to keep burns clean and dry to prevent infection. If you have a minor burn, run cool water over the area for several minutes and then cover it with a sterile bandage.
