Does everyone have demodex mites?

Demodex mites are microscopic organisms that use hair follicles and oil glands as part of their life cycle. They can be part of the normal skin environment, particularly on facial skin, without causing visible disease. Problems are considered when the skin shows a pattern of inflammation such as persistent redness, roughness, itching, burning, bumps, or eyelid irritation.

A test that identifies mites needs to be interpreted alongside the examination. Skin sensitivity, barrier damage, dermatitis, folliculitis, and [Rosacea](/conditions/rosacea/) can produce overlapping symptoms. Treating a test result without matching symptoms may irritate the skin and miss the real cause.

If your skin feels well, no special mite-clearing routine is needed. Keep cleansing gentle, moisturise when dry, and avoid squeezing bumps or using harsh exfoliants. If symptoms are troublesome, arrange a dermatology assessment rather than trying several products at once. For scalp concerns, ask whether [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/) is relevant to the diagnosed condition.

Seek routine care for persistent facial itching, burning, scaling, bumps, or repeated eyelid irritation. Prompt assessment is needed for eye pain, blurred vision, light sensitivity, pus, rapidly increasing swelling, or spreading redness. These warning signs may indicate eye or skin inflammation that needs treatment beyond basic hygiene.

Are mites actually causing my symptoms, or are they an incidental finding? What other conditions should be considered? Do I need treatment, and what improvement should I watch for before returning for review?
