Common forms of skin rash that may appear on the face include rosacea, atopic dermatitis, contact dermatitis, psoriasis, shingles and acne, according to Mayo Clinic. Frequent causes and drivers of facial rash include genetic conditions, allergic reactions, stress, heat and humidity, and a lack of specific nutrients in the diet.
Rosacea is a condition that commonly produces reddened and dry skin, and it affects over 16 million Americans, according to the National Rosacea Society. Although medical professionals do not fully understand what causes rosacea or how to cure it, there are options for treating and managing the symptoms, such as prescriptions, oral and topical medications, and identification and avoidance of environmental trigger factors.
Eczema, or atopic dermatitis, affects between 10 and 20 percent of infants and around 3 percent of adults in the United States, according to WebMD. It is a recurrent condition that tends to periodically flare up and subside, but the causes of severe episodes vary.
Contact dermatitis is often the result of an autoimmune response to an allergen or irritant, such as poison ivy or a corrosive chemical, explains Mayo Clinic.
Psoriasis is a common, chronic disease that alters the life cycle of skin cells, causing dead cells to build up rapidly near the skin's surface, yielding dry, itchy, red patches, according to Mayo Clinic.
Shingles is a painful malady of the skin that results from a reactivation of varicella zoster, the same virus that causes chickenpox. A shingles vaccine called Zostavax is available, according to the University of Maryland Medical Center.
