What Can Cause Rosacea?

The exact cause of rosacea is not known. It’s an inflammatory disease. The targets of inflammation are blood vessels in the skin and eyes as well as glands of the nose. It’s possible to consider rosacea as an allergy where symptoms occur in the skin of the face and upper torso. 


As with allergies, predisposition to rosacea runs in the families, mostly of North European origin. Additionally to the genetic component, there is an environmental factor. The people that live in cities have rosacea more frequently than people who live in the countryside. 


The triggers of rosacea are environmental and lifestyle. For example, changes in weather such as extreme hot temperatures can trigger rosacea. Possibly the most frequent rosacea trigger is strong emotions. On the other hand, many skin care products or medications that widen blood vessels also trigger rosacea. 


There are also types of food and drink that cause rosacea:

  • Any alcohol containing drink 
  • Spicy food containing any sort of pepper 
  • Food containing a compound that gives cinnamon its distinctive flavour.

Another group of hormones, female hormones estrogens are also involved in rosacea. But they have the opposite effect. Changes in levels of female hormones affect rosacea. For example, during the time before menopause, perimenopause decline of estrogens causes the surges in hormones that normally regulate body temperature. This causes hot flashes typical for rosacea.

Does Proactive Cause Rosacea?

Clinical studies of patients have shown that active ingredient of Proactive, benzoyl peroxide can cause rosacea aggravation. Although the concentration of benzoyl peroxide in Proactive is lower than in most medications, there is still an adverse effect.

Next stage is red bumps on the skin - papules that are caused by local inflammation of the blood vessels. If the inflammation persists, it attracts immune cells. Dead immune cells accumulation causes pustules formation.

What is The Cause of Ocular Rosacea?
