Medically Reviewed by Dr Sravya, MBBS, MS 


The dermatological condition rosacea, pronounced roe-ZAY-she-uh, is common and is characterized by facial flushing and the development of visible blood vessels. Additionally, it could show up as little pimples filled with pus.


These symptoms may go through phases of exacerbation that last for a few weeks to a few months, followed by phases of remission.
Rosacea may be misdiagnosed as acne, other skin conditions, or even a naturally pink complexion. Although rosacea can affect people of any age or race, middle-aged Caucasian women are the most commonly affected. Unfortunately, there is no recognized treatment for rosacea. However, there are approaches to control and lessen its symptoms.

Four different forms of rosacea exist:

Over 14 million Americans suffer from rosacea, which is a common condition. Although it can affect anyone, people with pale complexions are more likely to experience it, and women and those who were given the gender of a female at birth are more likely to do so. After age 30,
symptoms typically start to show themselves. Although rosacea can affect toddlers and teenagers, these instances are quite uncommon. The likelihood of the illness developing is increased if there is a family history of it. According to research, men and those who are born male may experience more severe symptoms as a result of delayed treatment, allowing the illness to worsen.

Rosacea: Is it an autoimmune disorder?

Rosacea’s origins and its probable classification as an autoimmune disease are still being studied. There is proof of immune system dysfunction in several rosacea subtypes. The body’s immune system’s main job is to protect the body from diseases that are foreign to it and can make people sick, including germs. A particular bacterium called Bacillus oleronius, which is common in people with papulopustular rosacea, can cause an autoimmune reaction. This reaction causes an overactive immune system to unintentionally target healthy skin cells, which aids in the emergence of rosacea symptoms. Identifying and managing ocular rosacea triggers skin care through a personalized skincare routine is crucial for effective symptom control. Alternatively, it is possible that the immune system displays increased sensitivity to
environmental changes in some rosacea cases. Temperature changes and sunshine exposure are two examples of alterations that could cause rosacea symptoms. As a result, the immune system may overreact in reaction to environmental changes, which leads to the development of rosacea symptoms.
