Patient's own account: 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.
