What should I do if my face is allergic, red, and rough?

When experiencing facial allergies, redness, and roughness, the following measures can help alleviate symptoms: 1. Avoid irritation: Discontinue the use of cosmetics, skincare products, or cleansers that may cause allergies. Avoid excessive rubbing or squeezing of the skin. 2. Cleanse and moisturize: Choose a mild, non-irritating facial cleanser. After washing your face, use a moisturizer suitable for your skin type to maintain skin hydration. 3. Anti-inflammatory and antiallergic treatment: Under a doctor's guidance, you may take antiallergic medications such as loratadine or chlorpheniramine, or apply topical anti-inflammatory agents such as calamine lotion or hydrocortisone cream to relieve allergic symptoms. 4. Cold compress: Soak a towel in cold or ice water and gently apply it to the affected area. This helps constrict blood vessels and reduce redness, swelling, and itching. 5. Dietary adjustment: Avoid foods that may trigger allergies, such as seafood and mangoes. Maintain a balanced diet and consume more foods rich in vitamins C and E, which can help strengthen the skin's resistance. 6. Seek medical advice: If symptoms persist or worsen, promptly consult a doctor for allergy testing to enable more targeted treatment.
