Rosacea is a common skin disease and often begins with a tendency to blush or flush more easily than other people. The redness can slowly spread beyond the nose and cheeks to the forehead and chin. Even the ears, chest, and back can be red all the time. Rosacea can cause more than redness. With time, people who have rosacea often see permanent redness in the center of their face.
There are so many signs and symptoms that rosacea has four subtypes:
- Erythematotelangiectatic rosacea: Redness, flushing, visible blood vessels.
- Papulopustular rosacea: Redness, swelling, and acne-like breakouts.
- Phymatous rosacea: Skin thickens and has a bumpy texture.
- Ocular rosacea: Eyes red and irritated, eyelids can be swollen, and person may have what looks like a sty.
Who Gets Rosacea?
Rosacea is common. According to the U.S. government, more than 14 million people are living with rosacea. Most people who get rosacea are:
- Between 30 and 50 years of age.
- Fair-skinned, and often have blonde hair and blue eyes.
- From Celtic or Scandinavian ancestry.
- Likely to have someone in their family tree with rosacea or severe acne.
- Likely to have had lots of acne — or acne cysts and/or nodules.
Women are a bit more likely than men to get rosacea. Women, however, are not as likely as men to get severe rosacea. Some people are more likely to get rosacea, but anyone can get this skin disease. People of all colors get rosacea. Children get rosacea.
What Causes Rosacea?
Scientists are still trying to find out what causes rosacea. By studying rosacea, scientists have found some important clues:
- Rosacea runs in families. Many people who get rosacea have family members who have rosacea. It is possible that people inherit genes for rosacea.
- The immune system may play a role. Scientists found that most people with acne-like rosacea react to a bacterium (singular for bacteria) called bacillus oleronius. This reaction causes their immune system to overreact. Scientists still do not know whether this can cause rosacea.
- A bug that causes infections in the intestines may play a role. This bug, H pylori, is common in people who have rosacea. Scientists cannot prove that H pylori can cause rosacea. Many people who do not have rosacea have an H pylori infection.
- A mite that lives on everyone’s skin, demodex, may play a role. This mite likes to live on the nose and cheeks, and this is where rosacea often appears. Many studies found that people with rosacea have large numbers of this mite on their skin. The problem is some people who do not have rosacea also have large numbers of this mite on their skin.
- A protein that normally protects the skin from infection, cathelicidin, may cause the redness and swelling. How the body processes this protein may determine whether a person gets rosacea.
Like psoriasis and eczema, there is no cure for rosacea at this time. Nonetheless, Affiliated Dermatology can diagnose and provide effective skin disorder treatment for this complaint. Many people are particularly troubled by this ailment because it often appears on the face as redness and bumps filled with pus. Ignoring rosacea symptoms only tends to make them worse, so it’s important to seek proper medical treatment. Rosacea is frequently treated with antibiotics or other oral medications.
