You know when you get a paper cut or similar, (not a scratch, a clean cut) and it stings and is really irritating, but it's not deep enough to bleed much if at all?
Whack some vaseline on it. You block the air from your nerves and get instant relief.
Also use it sometimes to prevent chafing, like before a long bike ride.
Native Americans discovered the use of petroleum jelly for protecting and healing skin.[4] Sophisticated oil pits had been built as early as 1415–1450 in Western Pennsylvania.[5] In 1859, workers operating the United States's first oil rigs noticed a paraffin-like material forming on rigs in the course of investigating malfunctions. Believing the substance hastened healing, the workers used the jelly on cuts and burns.
I'm pretty sure that most of what Neosporin is is Vaseline... And it makes sense. It's basically Vaseline with a mild antibiotic.
Vaseline is awesome for preventing scars too: when the wound is still open, use Neosporin, but after it closes up a bit and is just healing, switch to Vaseline and just keep it in Vaseline until it's totally gone.
