You would never know it by looking at her but Cindy Roden has a problem with her face.

"I couldn't figure out when I wasn't hot or cold, why my face was red," said Roden.

Cindy never considered rosacea until the doctor made the diagnosis.

"I take my medication and I use the ointments and I use makeup to cover it as best I can," said Roden.

So what is rosacea? It's a disease found on the face characterized by red cheeks and a red nose. The patient often looks flushed and has little red bumps that are sometimes mistaken for adult acne. And just below the surface of the skin, tiny, broken blood vessels can appear, followed by a red, swollen nose with bumps. Dermatologist Dr. Chris Huerter:

"What people don't understand is that it's a vascular disorder and what I mean by that is that it's an abnormality, an overreaction to blood vessels in the skin of the face. When these blood vessels open up, blood from lower in the skin comes to the surface and that's what makes a person very red and makes the skin feel hot," said Dr. Huerter.

Rosacea affects adults thirty to fifty and sometimes beyond. What triggers it? Cindy will tell you hot drinks, spicy food and a camera crew interviewing her about rosacea. Just take a look at the side of her face during our interview.

"Probably it will disappear and go away. Now in the next couple of days, I could have a breakout due to this stressful situation," said Roden.

Cindy controls her rosacea with medicine. Because it's a chronic illness, you can never really get rid of it. Dr. Huerter says you can keep it in check and limit what it does to your skin.
