What should you know about Demodex folliculorum?

These tiny mites live around facial hair follicles and oil glands. Their presence alone does not prove that they are causing symptoms. When mite numbers or the skin’s inflammatory response become problematic, people may notice persistent redness, rough or sandpaper-like texture, itching, burning, sensitivity, small bumps, or eyelid irritation. Similar changes can occur with rosacea, eczema, acne, irritation from products, or infection, so symptoms cannot identify the cause by themselves.

A clinician may examine the skin and eyelashes and decide whether testing is useful. Diagnosis is based on the pattern, examination, and response to an appropriate plan rather than on seeing mites with the naked eye.

Use a gentle cleanser, avoid scrubbing, and pause products that sting or strongly irritate the skin. Do not share towels, eye makeup, or facial tools, and wash pillowcases regularly. If symptoms persist, arrange a dermatology assessment and mention eye irritation, rosacea history, recent product changes, and any treatments already tried.

Treatment may involve a prescribed topical or other targeted approach chosen for the affected skin. Follow the directions exactly and avoid applying non-prescribed insect products to the face or eyelids. Improvement can take time, and returning symptoms may need reassessment rather than repeated self-treatment.

Arrange medical review for persistent facial redness, repeated flares, worsening itch or burning, eyelid crusting, eye dryness, or recurrent bumps. Seek prompt care for eye pain, light sensitivity, reduced vision, facial swelling, pus, or rapidly spreading redness. These features may indicate a condition needing treatment beyond routine skin care.

Ask whether your pattern fits Demodex-related inflammation, rosacea, or another condition; whether the eyelids or eyes are involved; which treatment is appropriate; and how long to continue it before review.
