Please recommend a scar removal ointment!

I came to the hospital for my child's medical treatment.

It's healing well, but there will be a scar.

I'm waiting because I was told it would be good to start laser treatment.

They prescribe Kelicoat as a scar removal ointment.

I purchased this before, but I didn't see much of an effect.

Do you have any recommended scar removal ointments?
