Demodex folliculitis on the face: what to know

Demodex folliculorum are tiny mites associated with hair follicles and oil-producing areas. They can be present without causing symptoms, but an increased local reaction may produce clusters of small bumps, redness, rough texture, burning or itch. Facial follicle inflammation can resemble acne, rosacea or irritation from a product, so appearance alone does not confirm the cause.

A clinician may inspect the skin closely and consider the distribution, surface scale, eyelid symptoms, recent product changes and other causes of folliculitis. Avoid squeezing bumps, because this can worsen inflammation and injure the skin.

Use a gentle cleanser and lukewarm water, then pat dry. Pause harsh scrubs, picking, fragranced products and heavy occlusive creams if they make the area sting or feel congested. Keep pillowcases, face cloths and makeup tools clean, and do not share them.

Arrange a dermatology assessment if bumps persist, spread or recur. Treatment depends on the examination and may involve a prescribed mite-directed or anti-inflammatory approach; antibiotics are not automatically appropriate because not every follicle eruption is bacterial.

Seek prompt medical care if facial swelling is rapidly increasing, the skin becomes hot and very tender, pus is spreading, or you develop fever or feel unwell. Get urgent attention for eye pain, vision change, marked eyelid swelling or a rash close to the eye. A non-healing sore or sudden widespread eruption also deserves assessment.

Ask whether the pattern fits folliculitis, rosacea or contact irritation; whether a close examination or sample is useful; which products should be stopped; and how long to use any prescribed treatment before reviewing the response.
