There are many causes of skin heat in the zygomatic area, which can be categorized as physiological and pathological, with pathological causes such as rosacea and contact dermatitis. 1. Physiological: This symptom may occur if the skin has been exposed to the sun for a long time recently, or if a hot compress has just been applied to the area. These are normal physiological phenomena and do not require special treatment. 2. Rosacea: formerly known as rosacea, is a chronic inflammatory skin disease that occurs in the middle of the face and is characterized by persistent erythema and dilated capillaries. Erythema occurs symmetrically in the middle of the face, especially on the nose, cheeks, forehead, jaw, etc., and there is persistent redness, often accompanied by dryness, burning or tingling sensation. 3. Contact dermatitis: it is an acute or chronic inflammatory reaction that occurs in the contact area of skin and mucous membrane after contacting certain exogenous substances. Typical skin lesions are erythema with clear boundaries, and the morphology of the lesions is related to the contact material, which can be self-conscious itching and burning. There are more reasons for skin fever in the zygomatic region, and it is recommended to go to the hospital in time to clarify the cause and standardize the treatment.
