Introduction
In general, allergic reactions around the corners of the mouth may be caused by vitamin deficiencies, food allergies, contact dermatitis, perioral dermatitis, angular cheilitis, or other reasons.

Patients are advised to seek timely medical attention when symptoms occur and to receive standardized treatment under a doctor's guidance, which can help promote recovery.
Generally, allergic reactions around the corners of the mouth may be caused by vitamin deficiency, food allergies, contact dermatitis, perioral dermatitis, or angular cheilitis. Treatment should be based on the specific cause. Details are as follows:
1. Vitamin Deficiency
Imbalanced nutrition in daily life, especially insufficient intake of vegetables and fruits, may lead to inadequate levels of vitamins in the body and result in allergic symptoms. Under medical guidance, treatment may include vitamin D drops or B-complex vitamin tablets.
2. Food Allergy
When allergens are ingested or come into contact with the skin, allergic reactions around the corners of the mouth may occur, including itching, redness, and swelling of the lips and mouth corners. In severe cases, medications such as cetirizine hydrochloride tablets or loratadine tablets can be used under a doctor's supervision.
3. Contact Dermatitis
This condition is usually caused by skin exposure to external substances such as pollen or animal hair. Inflammatory stimulation may lead to redness and itching. Treatment options include topical application of compound acetic acid dexamethasone cream or oral administration of methylprednisolone tablets, under medical guidance.
4. Perioral Dermatitis
This may be related to long-term use of topical corticosteroids or excessive use of facial cosmetics, leading to itching and burning sensations around the mouth. Medications such as pimecrolimus cream or tacrolimus ointment can be used under a doctor’s direction.
5. Angular Cheilitis
Angular cheilitis is a common perioral skin condition that may be triggered by various factors, including cold, heat, dryness, vitamin deficiency, or bacterial infection. It causes cracking, pain, and itching at the corners of the mouth. Patients may use antifungal creams such as clotrimazole cream or miconazole nitrate cream as directed by a physician.
Avoid scratching with hands and maintain local cleanliness. Individuals experiencing discomfort should seek timely medical attention and receive standardized treatment under professional guidance to promote recovery.
