Demodex red flags help identify when symptoms need medical attention instead of home treatment alone. Severe swelling, vision changes, intense pain, spreading infection, unexplained hair loss, persistent eyelid inflammation, bleeding, ulceration, or symptoms that continue despite treatment may signal a deeper issue. Many cases of rosacea, blepharitis, folliculitis, perioral dermatitis, and scalp irritation improve with proper care, but some require immediate professional evaluation. Recognizing these Demodex red flags early helps prevent long-term complications and supports faster healing.
