ABSTRACT: Rosacea is a surprisingly little-known disorder that affects almost 15 million people in the United States. Classified into 4 subtypes, rosacea is often misdiagnosed as sunburn, acne, or conjunctivitis, and it is often accompanied by acne and/or seborrheic dermatitis, which may complicate treatment. Although no cure is available, proper care can lead to relief of symptoms and delay of exacerbations. Effective rosacea management includes patient education, skin care, and therapy. Medication choice should take into account the need to preserve barrier function and to avoid exacerbation of concomitant skin disorders. Patients' involvement in designing their own course of treatment is likely to lead to better outcomes. They must not only consistently apply medications but also avoid triggers and follow cleansing and moisturizing regimens. Dermatologic nurses can play an important role in fostering treatment success through education and support.
