A 38-year-old female athlete enters the clinic with a 4-week history of mild rash. She complains that her face can be burning and stinging, especially after exercising and being exposed to sunlight. She is very frustrated with her skin condition as it has been affecting her training programme recently. On examination, there is a fixed central facial erythematous rash and several pustules on her forehead, nose and cheeks. A diagnosis of rosacea is suspected.
