Why do both sides of my cheeks keep itching?

Generally, persistent itching on both sides of the cheeks may be caused by factors such as dry skin, elevated skin temperature, contact dermatitis, seborrheic dermatitis, or neurodermatitis. Measures such as maintaining skin moisture, cooling the skin, and using medications as directed by a physician can be taken. It is advisable to seek timely medical attention and follow medical guidance for treatment. Specific causes are as follows:

1. Dry Skin: If the skin on both sides of the cheeks becomes excessively dry and lacks sufficient moisture and oil, the skin's barrier function may become compromised, leading to itching and possibly redness. Use moisturizing toners and lotions to hydrate the skin and maintain its moisture. Avoid using overly harsh facial cleansers or washing the face too frequently, as this may exacerbate dryness.

2. Elevated Skin Temperature: Increased skin temperature can be caused by high ambient temperatures, emotional excitement, vigorous exercise, or similar factors. Excessively high skin temperature accelerates evaporation of surface moisture, causing dryness and dehydration, which can lead to itching and possibly a mild burning sensation. Applying cold compresses can help cool the skin, while adequate hydration and moisturizing are also important. Avoid prolonged exposure to high-temperature environments, reduce intense physical activity, and maintain emotional stability.

3. Contact Dermatitis: When the skin on both sides of the cheeks comes into contact with certain irritants or allergens, an inflammatory reaction may occur, causing symptoms such as itching, redness, and swelling, sometimes accompanied by blister formation. As directed by a physician, topical treatments such as calamine lotion, mupirocin ointment, or clobetasol propionate cream may be used to relieve itching and inflammation.

4. Seborrheic Dermatitis: Seborrheic dermatitis may be associated with factors such as heredity, endocrine disorders, and fungal infections. These factors can cause overactivity of the sebaceous glands, leading to excessive oil production, skin inflammation, and itching, often accompanied by oily skin. Under a physician's guidance, medications such as tacrolimus ointment, pimecrolimus cream, or itraconazole capsules may be used to exert anti-inflammatory and antimicrobial effects.

5. Neurodermatitis: Neurodermatitis is a chronic inflammatory skin condition primarily influenced by dysfunction in the inhibitory and excitatory functions of the cerebral cortex. Emotional fluctuations, mental stress, anxiety, and other factors can increase cortical excitability, triggering or worsening symptoms, which may include a burning sensation. Antiallergic medications such as loratadine tablets, cetirizine hydrochloride tablets, or epi-stitting capsules may be used under medical supervision.

In daily life, adjusting dietary habits and engaging in regular physical exercise can help enhance overall immunity.
