Hi,
You have not described the nature of the
rash nor is the photo available but nonetheless the most common causes for
rash on the face would be allergy and acne.
Azelaic acid (FINACEA Gel), 15%, is indicated for topical treatment of inflammatory papules and pustules of mild to moderate rosacea.
Rosacea begins as erythema (flushing and redness) on the central face and across the cheeks, nose, or forehead.
