Which skin disease?

Hello everyone, we are hoping for help from doctors or those affected who have already seen something like this or perhaps experienced it themselves.

We've now seen three doctors (a pediatrician and two dermatologists). Each one has a slightly different opinion and prescribed different ointments. But we don't need to treat the symptoms alone; we want to prevent them.

This concerns an 8-year-old child. For two weeks, she has had multiple inflamed spots. Initially, a small white spot appears. Some of them then become red, swollen, and itchy. But almost all of the spots look like pus inside. Then, after a week, the spots subsided, and the skin peeled off. Rivanol ointment was applied to them in the evening.

We don't have pets. We've already removed the bed and replaced everything. We even changed the entire room so we can sleep without taking anything out of the room.

We don't want to completely prejudge the opinions, so we won't say explicitly what each of the three doctors said. But we've tried everything. Small pimples appear daily, and not all of them turn into hives or pustules. I'm attaching pictures of two different areas, from the beginning to the present.
