Malar rash is a distinctive facial rash that typically appears as a butterfly-shaped pattern across the cheeks and nose. It is often associated with autoimmune conditions, particularly lupus erythematosus. The rash can vary in color and may be flat or raised, sometimes accompanied by other symptoms like redness or swelling. This type of rash can be triggered by sun exposure, stress, or certain medications. While it is not contagious, it can indicate an underlying health issue. Treatment usually focuses on managing the underlying condition and may include topical creams or medications to reduce inflammation.
