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.
