Demodex mites and skin: what to know

Demodex are microscopic mites associated with hair follicles and oil glands. Their presence is not the same as a visible skin infection, and many people have no related complaint. When the surrounding skin becomes inflamed, the surface may feel gritty or sensitive and may show small bumps, redness, or flaky areas, often on the central face.

Skin appearance alone cannot confirm the cause. Acne, rosacea, eczema, irritant dermatitis, and bacterial or fungal conditions can overlap with these features. A clinician considers timing, distribution, itch or burning, products used, and eye symptoms before recommending a mite-directed approach.

Wash gently, moisturise with a non-irritating product, and use daytime sun protection if tolerated. Avoid squeezing bumps, harsh scrubs, and frequent product changes. Keep cosmetics and applicators clean, and do not share eye makeup. If inflammation continues, a dermatologist may recommend a prescription medicine for the specific area; treatment for [Rosacea](/conditions/rosacea/) may be considered when the pattern includes persistent facial flushing or sensitivity.

Seek an appointment for a rash that lasts, repeatedly returns, or affects the eyelids or eyelashes. Prompt assessment is warranted for eye pain, vision change, strong light sensitivity, marked swelling, pus, fever, or rapidly expanding redness. These symptoms should not be attributed to mites without examination.

What is the most likely cause of my skin changes? Are the eyelids or follicles involved? Would a sample or close examination help? Which products should I stop? What treatment is suitable for my skin area and how will we judge improvement?
