The Mites Among Us: How Demodex Can Impact Your Eye Health
Explore the world of Demodex mites—tiny parasitic creatures living in your hair follicles and sebaceous glands—and learn about their impact on eyelash health. Understand the symptoms of a Demodex overgrowth, such as irritation and lash loss, and discover effective treatments and prevention tips for maintaining healthy, comfortable eyes.
When it comes to the health of our eyelashes, most are worried about serums, curlers, and other cosmetic products. But have you considered what might be living at the base of your lashes? Enter the world of Demodex, commonly known as lash mites. Today’s educational blog post will provide an overview of Demodex, and how the presence of these tiny mites on eye lashes can impact overall lid and lash health.
What Are Demodex Mites?
Demodex mites are tiny, parasitic creatures that live in the hair follicles and sebaceous (oil) glands of human skin¹. There are two primary species that affect humans: Demodex folliculorum and Demodex brevis¹. Demodex folliculorum prefers the hair follicles, including eyelashes and facial hair¹. While Demodex brevis, the smaller of the two species, predominates on the trunk, typically as solitarily mites within the sebaceous glands and ducts¹.
How Common Are Demodex Mites?
Surprisingly, Demodex mites are incredibly common¹. Studies suggest that a significant majority of adults have these mites living on their skin without even realizing it¹. Infestations often increase with age, with the prevalence of Demodex infestation being nearly 95% in individuals older than 71 years¹.
How Do Demodex Affect Your Eyelashes?
While these mites can without acute symptoms on the skin and lashes, they sometimes cause issues, particularly when their population grows excessively. Here’s how they can affect your eyelashes:
- Irritation and Inflammation: Excessive mite populations can cause irritation and inflammation of the eyelids and Meibomian glands, leading to inflammatory conditions such as blepharitis and Meibomian glands dysfunction (MGD)¹⁻³.
- Itchiness and Redness: Infested areas may become itchy and red, leading to localized discomfort and increased irritation from scratching and itching of the ocular and peri ocular skin¹⁻³.
- Lash Loss: In severe cases, the unregulated and untreated presence of a Demodex mite infestation can lead to lash loss due to follicle damage¹⁻³.

Symptoms to Watch For
Common symptoms indicating a possible overgrowth of Demodex mites include¹⁻³:
- Itchy eyes and eyelids
- Red, swollen eyelids
- A burning sensation in the eyes
- A sandy or gritty sensation along the lashline
- Dry eyes
- Crusty or sticky eyelashes, particularly upon waking
- Frequent eye infections
Diagnosis and Treatment
Diagnosing Demodex mites typically involves a close examination of the eyelashes and eyelid margins, sometimes using a microscope³⁻⁴. If an infestation is confirmed, treatments for Demodex overgrowth may include¹⁻⁴:
- Eyelid hygiene: Regular cleaning with a gentle cleanser can help reduce mite populations.
- Medicated ointments: In more severe cases, a doctor might prescribe medicated ointments to reduce the mite population and alleviate symptoms.
One Step for Better Eyegiene: Meet BIHOCL O.D.
Maintaining eye hygiene is crucial for overall eye health, and incorporating BIHOCL O.D., a pure HOCl-based eye care solution, into your daily routine can make a significant difference in just one step.
Hypochlorous acid (HOCl) is a molecule naturally occurring in the human body, and when manufactured and applied topically, it is known for its gentle yet effective antimicrobial properties.
As a pure HOCl spray for ocular hygiene, BIHOCL O.D. harnesses these properties to provide a safe and soothing way to cleanse and protect your eyes from harmful bacteria, allergens, and debris. Unlike harsher chemical solutions, HOCl is non-toxic and biocompatible, making it ideal for sensitive eye areas and for patients of all ages.
By adding this simple step to your eye care regimen, you can reduce the risk of infections, soothe irritation, and promote overall eye health, ensuring your eyes remain comfortable and clear every day.
Demodex Prevention Tips
Maintaining good eyelid hygiene is key to preventing an overgrowth of Demodex mites. Here are some tips¹⁻⁴:
- Cleanse your face, eyelids, and eyelashes thoroughly, especially before bed, ensuring to remove any cosmetics or skin care products.
- Avoid sharing eye makeup or using old or expired makeup products.
- Keep your towels and bedding clean and change them regularly.
Final Thoughts
Demodex mites, though microscopic and often unnoticed, are a common part of the human skin microbiome¹⁻⁴. While they usually coexist peacefully with their hosts, excessive populations can lead to discomfort and eyelash issues¹⁻⁴. Proper eyelid hygiene and regular cleaning can help keep these tiny inhabitants in check, ensuring your eyelids and lashes remain healthy¹⁻⁴. If you experience persistent symptoms, consulting a healthcare professional is the best course of action.
