Colonization is called demodex dowdy And it poses a challenge to doctors in terms of correct diagnosis and treatment. Changes do not respond to standard antibacterial agents, steroids, or antibiotics.
Two types of this spider parasitize on human skin. Human Demodex (Demodex folliculorum) inhabits the meibomian glands located in the margins of the eyelids, which produce the meibum, an oily secretion that lubricates the eye. Contributes to the blockage of these glands and the development of eye problems. It is particularly developmental demodicosis purdah. It can also nest in the eyebrows, where it also causes inflammation and their loss.

The second type is Demodex is short (Demodex brevis). She lives in the hair follicles, where there is an exit for the sebaceous glands that produce sebum. It colonizes those places where it is found most densely, that is, mainly the face and scalp. It is the cause of the formation of purulent eruptions.
Demodex feeds on dead and flaky epidermal cells and the secretion of the sebaceous glands, causing their blockage, follicular keratosis and Local inflammation. It also favors bacterial skin infections, and its droppings work Allergenworsening of the rash; They can also infect “their” Bacillus and Bartonella bacteria.
Symptoms of demodicosis of the skin Visible to the naked eye are:
- purulent pustules, thickening and blisters,
- the bread
- skin roughness,
- Peeling skin.
The changes appear mainly in the oily areas of the face. they Typical site are the regions:
- on the cheeks
- on both sides of the nose
- on the forehead
- around the ear canals.
Characteristic These changes are dilated holes in the hair follicles, an erythematous halo, and a gray or light brown plug. In the center, white, thread-like gelatinous structures 1-3 mm long may appear.
The effect of parasite implantation is destruction of the sebaceous glands; and changes that lead to scarring and discoloration. It is believed that demodectic dermatoses are involved in the development of perioral inflammation or folliculitis;. The parasite can also develop in other places, for example on the scalp, causing hair loss. However, it also happens that it inhabits the sebaceous glands of the eyelids.
Demodex is common. It is estimated that the carriers are 20-80 percent of the populationNot everyone causes skin problems. Its incidence increases with age. Usually, it does not cause major problems, but when it multiplies (more than 5 mites per 1 square centimeter of skin), the effects of its activity can become stressful.
Which is susceptible to boredom? These are especially people with weakened immunity and other skin diseases, in particular:
- use of anti-inflammatory creams with steroids,
- with disease of the skinAnd
- with pink countAnd
- over 70 years old
- taking immunosuppressive drugs,
- during chemotherapy,
- chronic renal failure during hemodialysis,
- With HIV and AIDS.
Demodex can be infected through direct contact contact with the carrier Or his personal items such as a towel, bedding, and cosmetics. This mite is also transmitted with dust that settles on the skin. It is especially favored because of sebum, a very rare peeling in case of keratosis of the epidermis and the lack of proper skin hygiene (in addition to washing towels and pillowcases very rarely). Most often women are affected, which is associated with the use of cosmetics, especially foundation and face powders.
The problems with demodex are getting worse in the warm months. However, it should be noted that the parasite avoids the sun’s rays (hence the changes calm down a little, moreover, the mite dies at temperatures above 54 ° C) and reaches the surface of the skin only at night. That is why the treatment of demodicosis requires appropriate measures, especially in the evening.
To get rid of demodex, the infection must first be diagnosed. reveal it parasite It is possible on the basis of scraping examination of skin lesions under a microscope. behind Nuisance test You have to pay PLN 30-40, although in some places it costs PLN 100-120 (you can also take a sample yourself and send it for analysis).
Demodex cannot be fought with ordinary means, and peels and treatments will not help. Effective treatment is carried out using Medicated creams It contains compounds such as:
Treatment, that is, lubrication of the skin, especially at night, should be long enough. The idea is to kill not only the adults, but also those that hatch from eggs that are lodged in the pores of the skin. He thinks it should go on 4 months at least. However, after a few weeks you can see improvement (the development cycle of Demodex lasts 15-21 days), and after 12 weeks when using ivermectin Parasite numbers are reduced by 99%.
Useful in treatment It may also be sulfur compounds, benzyl benzoate, and salicylic acid tea tree oil. However, be careful, as they can overly dry and/or irritate the skin, exacerbating problems.
