Do hives on my face look like small white head pimples?

White head pimples. White head pimples on face may be due to milia. Milia are small deposits of keratin under the skin forming cyst like structures. It is abenign condition zthey are best removed by a dermatologist.
Sometimes. Hives may take form of lumps (like after insect bite) or small pimple-like bumps. Hive often itches, whereas actual pimples do not usually feature that. I would suggest a consult with local dermatologist to diagnose & recommend treatment.
