Demodex folliculorum — shortened as D. folliculorum — is a kind of the parasitic demodex mite. D. folliculorum mites live in or around the hair follicles on your face.
Generally, D. folliculorum mites are harmless to humans. At normal levels, these mites benefit your skin by removing dead skin cells, oils, and hormones found around hair follicles, all of which can clog up your pores. But, in large numbers, they can irritate your skin and cause other related skin problems.
Without treatment, D. folliculorum infections can lead to rosacea-like symptoms. You may show inflamed skin and rashes as well as severe acne.

Diagnosis of D. Folliculorum Infection
Generally, you may not know if you have high concentrations of D. folliculorum on your skin until they experience a flare-up. That's because these microscopic mites aren't detectable with the naked eye. To diagnose D. folliculorum, your doctor will take a small tissue sample.
The doctor collects the sample by scraping the affected skin. They then examine it under a microscope.
This helps the doctor diagnose a D. folliculorum flare-up. Depending on the number of D. folliculorum, your doctor will prescribe treatment.
Treatments for D. Folliculorum Infection
Some home remedies backed up by medical studies include using a 50/50 solution of tea tree oil and water. You can use it for short-term treatments.
You can also clean your face with gentle cleansers twice daily. Exfoliating the skin twice weekly to remove dead skin cells is also recommended.
Medical treatments for D. folliculorum infection can come in many forms. For D. folliculorum on the eyelashes, your doctor may prescribe a medical ointment. This ointment traps D. folliculorum mites, preventing them from laying eggs.
Along with medical ointments, your doctor may prescribe creams, gels, or face washes that include:
- Benzyl benzoate
- Salicylic acid
- Selenium sulfide
