What causes rosacea?

The exact cause of rosacea is unknown, but there are several factors that are thought to contribute to its development, including:

Genetic factors: Rosacea is more common in people with a family history of the condition. Certain genes may make individuals more susceptible to developing rosacea when they are exposed to certain environmental triggers.

Immune system dysfunction: Rosacea is characterized by inflammation of the skin, and it is thought that the immune system may play a role in triggering this inflammation.

Blood vessel abnormalities: People with rosacea often have dilated and easily visible blood vessels on the face. It is thought that these abnormalities may contribute to the redness and flushing seen in rosacea.

Environmental factors: Certain environmental factors, such as exposure to sunlight, extreme temperatures, and certain chemicals or skin care products, can trigger or worsen rosacea.

Hormonal factors: Rosacea is more common in women than in men, and it can be aggravated by hormonal changes, such as those that occur during pregnancy or menopause.

It's important to note that rosacea is not contagious and it is not caused by poor hygiene. While the exact cause of rosacea is still unknown, understanding these contributing factors can help individuals manage their symptoms and reduce the impact of the condition on their daily lives.
