What causes rosacea?
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.
How do dermatologists treat rosacea?

To treat rosacea, a dermatologist first finds all of the patient’s signs and symptoms of rosacea. This is crucial because different signs and symptoms need different treatment.
Treatment for the skin includes:
– Medicine that is applied to the rosacea
– Sunscreen (Wearing it every day can help prevent flare-ups.)
– An emollient to help repair the skin
– Lasers and other light treatments
– Antibiotics (applied to the skin and pills)

Dermatologists can remove the thickening skin that appears on the nose and other parts of the face with?
– Lasers
– Dermabrasion (procedure that removes skin)
– Electrocautery (procedure that sends electric current into the skin to treat it)

When rosacea affects the eyes, a dermatologist may give you instructions for washing the eyelids several times a day and a prescription for eye medicine.
