Skin Scraping for Demodex – What is it?

If you have skin problems, it is possible that the cause is the presence of Demodex. Demodex is a type of microscopic mite (Demodex folliculorum and Demodex brevis) that normally lives on human skin in symbiosis with the host. However, if these mites overpopulate, they can cause changes and inflammation on the face, eyelids, as well as the scrotum and anal regions.

Symptoms of Demodex Infection

Symptoms of Demodex infection can vary, but the most common include itching, redness, and skin rashes. The infection most frequently appears on the face, especially around the eyes, nose, and mouth. In some cases, swollen skin glands may also occur.

Demodex in Children

Young children under the age of five rarely test positive for Demodex, but transmission from parent to child can happen. After puberty, the number of sebaceous glands increases, and Demodex becomes more prevalent. As people age, the likelihood of having Demodex increases, with half of individuals over 50 testing positive for it, often without symptoms.

Skin Scraping for Demodex

To detect the presence of Demodex on your skin, the best method is a skin scraping test. This procedure is quick and painless. Through microscopic examination, the presence of these mites is easily diagnosed. Results are typically available the same day or the next day.

How is Demodex Transmitted?

Demodex is transmitted through direct contact (skin-to-skin contact between individuals) or through sharing personal items (such as cosmetics, towels, toys, etc.). Beauty salons that do not maintain proper hygiene can also be potential sources of Demodex transmission.

Treatment of Demodex

It is important to note that the presence of Demodex on the skin is not always associated with disease or symptoms. Some individuals naturally have a small number of mites on their skin without any issues. However, in cases of Demodex infection, known as Demodicosis, symptoms can be quite uncomfortable and require appropriate treatment. You should consult a dermatologist, who will prescribe adequate treatment based on the clinical picture, typically in the form of topical medications. In some cases, oral medication may be necessary to completely eliminate the mites from the skin.
