How do I fix a scar above my cupid's bow?

When I was in the third grade I was running during recess; I fell and did a perfect faceplant and slid. This resulted in a scar on my Cupids bow and my philtrum so my lip looks smaller and my Cupid's bow looks like somebody got their finger and whiped it off. I have really thin lips so they're chapped year round so I can't wear lipsticks or anything. I would just prefer to get them fixed so I dont look like a drawing somebody smudged.
