How do i?

Hello! I'm amaoto and i do self harm. And i need help about these red scars, i waited for a mouth, they're still a lil bit like lines that don't match my skin and not white and noticeable, i read on a post that i should never use anything with alcohol, the problem is i used hand sanitizer, do u guys have any way i can reduce the lines? Or make them white?

Thank u! 🩶
