Scarring after at home mole removal 3 years ago. What is my best option for minimizing its appearance? (photos)

Around 2/3 years ago I made the awful decision to remove an upper lip mole that I was teased about with apple cider vinegar at home, I was only 15 at the time and didn’t know any better, scarring never even crossed my mind. After I removed it it was really red and back then I didn’t understand the importance of sunscreen, like I do now. The scar is shiny and very noticeable and I have zero self confidence. What’s the best way to help the appearance of this? Im desperate at this point.
