Patient description (medical language): A 41-year-old woman comes to the dermatology clinic complaining of facial redness, especially on her forehead and cheeks. She noticed that the redness gets worse in the summer and after sun exposure. She is otherwise healthy. On physical examination, she has multiple papules and pustules present on her forehead, cheeks, and nose on a background of erythema and telangiectasias. There are no other lesions or nodules. The patient is married and has 2 children who are 5 and 9 years old. She has IUD and doesn't wish to have more kids. She does not smoke or drink alcohol. Her vital signs are normal, and BMI is 21.

Patient description (patient's own words): I'm 41, married with 2 lovely kids who are 5 and 9 years old. I have an IUD and I don't want to have more kids. I don't smoke or drink alcohol. I had to go to the dermatology clinic because I had terrible redness on my face, especially on my forehead and cheeks. It got worse in the summer and after being under the sun. I'm usually healthy. They conducted a physical exam and they found several lesions and pustules on my forehead, cheeks and nose and they also found some signs of erythema and telangiectasia. My vitals were normal, and my BMI is 21.

Does the patient match the trial criteria? 1
