my baby fell down from while cycling she got injured at chin ,blood clot r some kind of scar ,how to get rid of that,any oint cream pls suggest

A. with time fades. scars n marks vanish slowly with time. you can put olive oil and massage daily. however it's a time taking process. another option is plastic surgery. best to show a specialist. he will diagnose n find the root cause only as that's best ok. try to avoid self medication as that can be deleterious in long run as well
