What kind of doctor treats Demodicidosis?
A primary care doctor can often diagnose and treat demodicidosis, but severe cases may be referred to a dermatologist. Eye symptoms may need an ophthalmologist. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Demodicidosis is a skin problem caused by tiny Demodex mites, which are so small you cannot see them without a microscope. Many people carry these mites their whole lives and never have any trouble. Demodicidosis happens when the mites grow in numbers that are too high, and the skin starts to react to them.
Symptoms
The signs are often mistaken for acne or rosacea. Common signs include red, itchy, or rough skin, small pimple-like bumps, and burning or stinging. The eyes can be affected too. Symptoms often show up on the face, especially the cheeks, nose, forehead, and chin.
Causes and who gets it
Demodex mites are normal on human skin, and most adults have them. The trouble usually starts when the mites multiply beyond their usual numbers, which can happen when the immune system is weakened. Having too many mites is not caused by poor hygiene.
How doctors diagnose it
A doctor usually starts by looking at the skin and asking about symptoms. One common test is a skin scraping, which is examined under a microscope to count the mites. A biopsy is used less often.
Treatment
Treatment aims to bring the number of mites back down to a normal level. Doctors may prescribe medicated creams or lotions, or in some cases a pill that kills the mites. Washing bedding and towels in hot water can help keep mites from coming back.
When to see a doctor
See a doctor if you have red, itchy, or bumpy skin that does not go away with regular skin care, or if your eyes are red and irritated.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid with a flat monthly fee instead of using insurance for visits, while a concierge doctor usually charges more and often works alongside insurance. These doctors often offer longer visits and easier access, which can be a good fit for skin problems like demodicidosis.

Common questions
Is demodicidosis contagious?
The mites themselves can pass between people through close skin contact. This is very common and usually causes no problems. Having symptoms is not simply a matter of catching mites from someone. Most people who carry the mites never get sick from them.
Can demodicidosis be cured?
Treatment can bring the mites back down to normal levels and clear the skin. However, the mites often live on the skin afterward. Some people need treatment more than once. Results differ from person to person.
Is demodicidosis the same as rosacea?
No, but they are related. People with rosacea tend to have more Demodex mites on their skin. The mites may play a role in making rosacea worse. A doctor can help figure out which condition is causing the symptoms.
Can I treat demodicidosis at home?
Washing bedding and towels in hot water and keeping the skin clean can help. Over-the-counter products usually do not get rid of the problem, though. A doctor can prescribe treatments that work against the mites. It is best to see a doctor for skin problems that do not go away.
