Where do Demodex mites come from?

Demodex folliculorum and related mites are microscopic residents of human skin. They feed on oils and shed material around follicles, often without causing any noticeable problem. Skin irritation may develop when mite numbers, blocked follicles, or the body's inflammatory response disturb the local balance. Redness, rough texture, itching, small bumps, or a crawling sensation can overlap with rosacea and other facial conditions, so seeing or suspecting mites does not identify the cause by itself.

Use a gentle cleanser, avoid scrubbing the face, and remove makeup before sleep. Wash pillowcases, towels, and eye-area cloths regularly, and avoid sharing these items while symptoms are active. A dermatologist can examine the skin and eyelashes and decide whether a targeted topical medicine or another treatment is appropriate. Do not apply household insect products or unprescribed essential oils to the face. If scalp or eyelash involvement is suspected, ask whether a suitable medicated cleansing treatment is needed.

Arrange a dermatology review if facial redness, itching, burning, or bumps persist, recur, or affect sleep and daily comfort. Seek prompt medical attention for swelling around the eye, eye pain, vision changes, spreading warmth, pus, or fever. These features can signal an eye or skin problem that needs assessment rather than self-treatment.

Ask whether your pattern fits demodicosis, rosacea, or another follicle condition; whether the eyelids or eyelashes need examination; how long to use any prescribed treatment; and which cleansers, cosmetics, and moisturisers are least irritating for your skin.
