welcome to healthcare magic.
if your daughter can see and the swelling has reduced and no bleeding and the type of injury
was a hit by the head there is no reason to take her to the doctor it will resolve on its own.
if you notice the bruising is taking a while to clear then you will need her to be checked out by the doctor.
the area on the face have a alot of blood vessels so a small impact can cause the veins to break and cause a bruise
which resolve by two to three days.
hope to have answered your query.
