ELI5 What does Neosporin do for an open wound?

I whacked my face into the concrete not too long ago and when I got to the store the clerk said I would definitely need some Neosporin. After 3 days of applying Neosporin the giant scrapes on my face were almost completely healed! I was genuinely amazed as I get scraped up all the time and don't do anything for them except some cleaning and a bandaid. What does Neosporin do inside my wound that makes it heal so much faster as well as how does the treating of a wound a certain way prevent scar tissue from forming? I don't know much about the body's healing process but as someone who gets hurt a lot I am realizing I may need that 5 year old explanation my mother never gave me.

For the most part, the healing was just your body doing its thing. The Neosporin contains several powerful antibiotics and antifungals which kill off anything which gets into the wound, allowing the body to spend its energy on healing instead of fighting an infection. In addition, the thick paste helps replace the natural barrier the skin provides, preventing the healing area from drying out and letting it heal more effectively.
