Mites Unmasked: Conquering Demodex Blepharitis

Mites Unmasked: Conquering Demodex Blepharitis

What is Demodex?

Demodex mites are microscopic organisms that naturally inhabit the hair follicles and oil glands of the eyelashes and can become problematic when their population exceeds normal levels. An overpopulation of these mites can lead to demodex blepharitis, which is a condition characterized by inflammation of the eyelids. Demodex blepharitis often presents with symptoms such as itching, redness, irritation, burning sensations, and crusty debris along the lash line. The mites can also contribute to the development of other ocular conditions like meibomian gland dysfunction and dry eye syndrome.

Who is at risk for demodex?

Older Age

Increasing age is one of the main risk factors for demodex, particularly in patients aged 60 and over. However, demodex mites can be found in younger patients with poor eyelid hygiene.

Poor Eyelid Hygiene

Demodex feeds on sebum, dead skin cells, and other debris found on the lashes. For patients with poor lid hygiene or eyelash extensions, excess sebum and bacteria can lead to an overpopulation of demodex mites. This excessive population can lead to inflammation, itching, redness and even loss of eyelashes. Proper lid hygiene practices such as regular cleansing and gentle scrubbing can help control and alleviate the symptoms of demodex blepharitis.


Rosacea has been shown to increase the risk of demodex-associated blepharitis by creating an ideal environment for it to thrive. According to the National Rosacea Society, patients with rosacea have approximately 18 times more mites compared to people who don’t have rosacea.

What are treatments for demodex blepharitis?

Effective management of demodex blepharitis involves maintaining good lid hygiene practices, such as regular cleansing of the eyelids with gentle cleansers or prescribed lid scrubs, warm compresses, and eyelid massage. In some cases, doctors may recommend medicated treatments like topical ointments or oral medications to control the mite population. By having an optimal eyelid cleansing routine this can help reduce the risk of developing demodex. We recommend using the following products to help treat demodex blepharitis:
