A rash on the face around the nose indicates conditions with causes that range from allergic reactions to environmental factors, explains the U.S. National Library of Medicine. Diseases such as lupus, eczema and impetigo can cause rash symptoms on the face.
Rashes are results of skin inflammation, notes the U.S. National Library of Medicine. Contact dermatitis rashes occur from exposure of the skin to chemicals from rubber or latex products, ingredients in soaps, dyes in clothing, or poison ivy. Seborrheic dermatitis most commonly occurs around the face, especially near the nose and mouth. This condition worsens with age, stress, changes in weather, oily skin and alcohol-based lotions. Rashes caused by eczema are usually scaly and itchy.
People who have impetigo experience red spots around the nose or mouth, WebMD adds. These become blisters, which ooze fluid. Treatable with antibiotics, it is the result of bacteria entering a cut on the skin.
One symptom of lupus is a red, butterfly-shaped rash on the face, reports Mayo Clinic. The rash usually occurs after exposure to sunlight, and is most visible around the nose and cheeks.
Most causes of rashes on the face are treatable with hydrocortisone cream, calamine lotion and the avoidance of allergens, according to the U.S. National Library of Medicine. Rashes accompanied by shortness of breath, facial swelling or fever require immediate medical attention.
