Inside Eyelash Mites
Overview and Symptoms of Eyelash Mites
Eyelash mites, or Demodex mites, are tiny parasites that live in hair follicles, primarily around the eyelashes. Most people host these mites without experiencing any issues, but they can become a concern when their population grows excessively.
There are two types of Demodex mites that inhabit human skin: Demodex folliculorum and Demodex brevis. Demodex folliculorum lives in hair follicles, while Demodex brevis resides in sebaceous glands connected to hair follicles. These microscopic creatures feed on dead skin cells and oils, which accumulate around the eyes. A small population of these mites is considered normal and healthy for the skin.
An increase in the population of eyelash mites can lead to noticeable symptoms. Common indicators include:
- Itchiness: An increased sensation of itchiness along the eyelid margins.
- Redness: The edges of the eyelids may show redness or swelling.
- Flaking: Dandruff-like flaking may occur at the base of lashes.
- Crusting: Crusting around the eyelashes may be noticeable upon waking.
- Loss of lashes (Madarosis): In severe cases, an abnormal loss of eyelashes could occur.
Individuals with certain conditions like rosacea or those with weakened immune systems may be more susceptible to high populations of these mites, leading to symptoms.
Awareness of these symptoms is essential for understanding this condition.

Causes and Contagious Nature of Eyelash Mites
Eyelash mites, or Demodex folliculorum, naturally inhabit the skin, residing in hair follicles, particularly around the eyelashes. For most individuals, the presence of these mites does not cause any issues. However, an excessive growth in their population can lead to problems.
The proliferation of Demodex populations can be attributed to several factors:
- Poor Hygiene: The absence of makeup removal or infrequent cleaning of the facial area provides a conducive environment for mite growth.
- Age: There is a tendency for higher mite populations in older individuals, potentially due to decreased immune function.
- Weak Immune System: Conditions that compromise the immune system can result in an increase in mite populations.
These factors are known to contribute to the presence and excessive proliferation of mites.
Eyelash mites are spread through close contact with individuals who have a high concentration of these organisms. Transmission can occur through the sharing of personal items like towels or eye makeup brushes that come into direct contact with the lashes or skin near the eyes.
It is recognized that the presence of eyelash mites is common and does not necessarily result in symptoms unless there is an overgrowth, which can cause conditions such as blepharitis (inflammation of the eyelids).
In conclusion, the presence of a few eyelash mites is a common condition. Certain conditions may encourage their overgrowth, leading to discomfort and potential eye health issues.
