Harm caused by Demodex subdermal mites
 |
|
 |
Damaged hair follicles by Demodex subdermal mites. Most subdermal mites parasitize in hair follicles, feed upon the skin cells of hair follicles and secrete toxins. |
Hair follicles are destroyed, pathogenic bacteria invade these areas, the metabolism is disturbed; problems with skin health appear, pimples pop out, pores become dilated, the skin becomes greasy and callous, and other skin disorders continue to appear. |
Demodex Production Effects

Demodex (Demodicosis) – this disease is widespread in all countries, and can appear at any period of the year.
According to CSRID data, 89% of the people are carriers of these parasites. The average age of women suffering from this disease is 44.5±2, and men – 38.3±5.4 years. 90% of the patients are women.
The disease is caused by the Demodex mite (follicle or pimple), which is detected in sebaceous glands in hair follicles. Demodex mites prefer areas emitting hyper sebaceous secretions.
The Demodex folliculorum lives inside hair follicles; Demodex brevis – in sebaceous glands.
They have a semi-transparent bristly body measuring 0.15-0.48 mm.
Demodex subdermal mites survive by eating cells accumulating the hair follicles, cosmetic substances spread over the skin, and oils (sebum) secreted by sebaceous glands.
Subdermal Demodex mites are hosts for many other pathogenic bacteria.
Every evening, mites can leave their hair follicles, and slowly walk around on the skin.
Returning to their hair follicles, they bring in huge quantities of harmful pathogenic bacteria, which they gathered on the skin surface.
Besides emitting great amounts of secretions, subdermal Demodex mites disturb normal metabolism.
The skin becomes inflamed and tuberous, takes on a rather dirty-grey shade of color;
it is covered with pimples, acne, sores, dilated pores;
the skin becomes greasy and callous, and other skin problems continue to appear.
The patient is disturbed by a tingling sensation on the skin, and severe itchiness in diseased areas.
The reproductive cycle of mites takes place in the following way:
egg, larva, nymph 1 (protonymph), nymph 2 (deutonymph), and imago (sexually mature mite).
The reproductive cycle lasts from 15 to 25 days. The female lays her eggs inside the hair follicles.
The larva hatches in about 60 hours; it remains motionless and nourishes itself generously.
The larva turns into a nymph 1 after about 40 hours, and into a nymph 2 after 72 hours.
It becomes mobile and starts moving along the surface of the skin.
After 60 hours, the nymph develops into an adult, which, in turn, lays its eggs inside the hair follicles, and dies there.
Skin atrophy and severe skin disorders are caused by intensive reproductions of Demodex mites.
Characteristic localization of mites – the so-called “Demodex triangle” – wings of the nose,
nasolabial fold and the chin. Mites also infect eyelashes, ear auricles, the scalp, and the neck.
If the disease lasts for a longer period of time, Demodex mites appear on the skin of the chest, and very rarely on the back (0.5-0.7% observations).
Anti-parasitic treatment quickly gets rid of the itching sensation,
which once again confirms that the leading role in this disease is played by the Demodex mite,
and negates the opinions of some dermatologists, who deny Demodex effects on the pathological process.
Many doctors consider follicle or pimple mites to be accompanying factors of acne rosacea.
Chinese dermatologists adhere to another point of view, as well as a number of scientists in our country
(S.T. Pavlov, O.K. Shaposhnikov, V.I. Samtsov, and I.I.Ilyin), who believe that Demodex represents an independent disease.
Infections are transmitted through direct contacts. There have also been cases of infections reported in beauty salons during facial cleansing treatments.
