Face mites, also known as Demodex folliculorum (D. folliculorum) are microscopic tick-like organisms. There aren't visible demodex mites on the face. They live in the hair follicles in your skin, especially around the eyelids and lashes, and feed on dead skin cells and oils.
What do Demodex mites look like? A Demodex mite is extremely tiny (0.15 millimeters [mm]–0.4 mm). It would take several of them to cover a pin head. Under a microscope, the mite looks slightly transparent and is covered with scales.
But demodex are actually quite harmless. They don't bite. You don't feel them crawling or laying eggs (though they do both, which, again, is unpleasant to think about). Face mites can, however, become a problem when they overpopulate and begin to accumulate in high density, causing red, itchy, bumpy skin.
Demodex mite densities can be measured in different ways and the presence of >5 mites per cm2 is required for a diagnosis of demodicosis. Two methods are commonly used to determine Demodex mite densities–a standardized skin surface biopsy (SSSB) and direct microscopic examination (DME).
At high concentrations, tea tree oil is a potent killer of Demodex mites. The problem is that solutions of 100% tea oil, or other high concentrations, are very irritating to the eye. So one approach is to thoroughly wipe the eyelashes and eyebrows with a diluted solution of tea tree oil, from 5% to 50%.
Itching, mainly at night: Itching is the most common symptom. The itch can be so intense that it keeps a person awake at night. Rash: Many people get the scabies rash. This rash causes little bumps that often form a line.
Direct contact or eggs present in dust as well as contact with infected towels, blankets, or sponges are the possible routes of Demodex spp. infection described in the literature [13, 14]. The use of facial creams or eyeliners has been considered as a potential route of Demodex spp.
If left untreated – or when poorly managed – adverse effects such as redness, inflammation, telangiectasia, MGD, and ocular allergy may persist. Patients must understand that long-term lid hygiene is required as Demodex is a chronic condition requiring chronic therapy.
Too many Demodex mites can cause uncomfortable symptoms that may include: Itchy or burning eyes, especially in the morning. Swollen eyelids. Crusty eyes.
They're known as Demodex or eyelash mites, and just about every adult human alive has a population living on them. The mostly transparent critters are too small to see with the naked eye. At about 0.3 millimeters long, it would would take about five adult face mites laid end to end to stretch across the head of a pin.
In the vast majority of cases, the mites go unobserved, without any adverse symptoms, but in certain cases (usually related to a suppressed immune system, caused by stress or illness) mite populations can dramatically increase, resulting in a condition known as demodicosis or demodex mite bite, characterised by itching ...
The mite, Demodex follicularum, spends its entire lifetime living in our skin follicles. In the daytime they feed on our oily skin secretions, at night they leave the pore to find mates, and find new follicles in which to have sex and lay their eggs.
6.2. 2 Demodex mites. Two species of mites infest human skin: (1) Demodex folliculorum and (2) Demodex brevis. These colonize the hair follicles of the eyelash, forehead, nose, cheeks, outer ears, chest, buttocks, and pubic areas (reviewed by Wesolowska et al., 2014).
But sometimes, people end up with too many mites burrowing into their skin, leading to demodicosis -- the infection that causes skin inflammation. People between ages 20-30 may be more vulnerable to demodicosis, as can older people and children under 5.
Speaking of mites that feed on human material, Demodex folliculorum (Simon) is one of three mite species living on your face. The microscopic critters are found across the human body, but are particularly dense near the nose, eyebrows and eyelashes.
Common interventions used for Demodex infestation include metronidazole-based therapies, permethrin, benzoyl benzoate, crotamiton, lindane, and sulfur. Short courses of metronidazole taken orally have shown efficacy in reducing Demodex density.
The results showed that the Demodex count dropped to zero in 3 weeks in five patients and in 4 weeks in another two patients without any recurrence 1 month later. These seven patients were younger (59.86 (8.7) year old), and had a mean count of 7.9 (4.1) before treatment.
Life cycle
The six-legged larvae hatch after 3-4 days, and the larvae develop into adults in about 7 days. It has a 14-day life cycle[6] [Figure 2]. The total lifespan of a Demodex mite is several weeks. The dead mites decompose inside the hair follicles or sebaceous glands.
The best option when trying to get rid of dust mites on your skin is to jump in the shower and thoroughly clean yourself with hot water and soap. The heat and soap should kill off any dust mites still on your body.
"Demodex mites live on our skin and are especially prominent in areas where we have a lot of oil like the face or the middle of the chest." Even worse, said mites thrive in unsanitary environments, like Xu's dirty pillowcase.
If mites are on you, take a hot shower with some medicated shampoo. Do this regularly if you have been having mite issues and for general cleanliness because this will dramatically reduce or eliminate mites.
Temperatures below 0 degrees C and above 37 degrees C are harmful to the mites. The lethal temperature is 54 degrees C, and the effective temperature that kills Demodex mites is 58 degrees C.
Treatment for face mite overgrowth can include washing your face, hair, and eyelashes, and exfoliating regularly. Some OTC options, including tea tree oil, may be helpful. Prescription drugs such as metronidazole and ivermectin may be necessary in some cases.
A healthcare provider may think you have mites based on your health history and a physical exam. Intense itching and many small, red bumps, like pimples, are seen. Burrows may also be seen. These look like thin, wavy lines.
