LO face has a long scratch

As long there's no bleeding, I don't think there's a need. Whenever my boy has a scratch, I just use a baby balm to spread over it. I use Inara Organics Soothie Woothie or Twinkle Multi-Purpose Baby Balm. Even used Vaseline before when I'm out of baby balm and it helps to reduce the redness and in a few days the scar becomes invisible. Unless ur baby's skin is sensitive , u can just use any baby balm.
