Facial dermatitis is a common skin problem, typically presenting with redness, swelling, itching, and red patches on the skin. Based on the patient's symptoms, it may be caused by an allergic reaction to cosmetics or decreased immunity. Here are some treatment and precautionary measures: 1. **Avoid allergens**: Immediately stop using all suspected cosmetics that may cause an allergic reaction. When choosing cosmetics, opt for fragrance-free and preservative-free products. 2. **Keep the skin clean**: Clean your face daily with a gentle cleanser and avoid using products with irritating ingredients. 3. **Use medications**: According to the doctor's advice, you can use Uriage Xémose cream to alleviate symptoms. If the symptoms are severe, consult a doctor to see if antihistamines or steroid creams are necessary. 4. **Avoid irritants**: Avoid washing your face with hot water and exposure to strong winds or sunlight to prevent further skin irritation. 5. **Moisturize**: Keeping the skin hydrated is crucial to relieve symptoms. Use fragrance-free and additive-free moisturizers. 6. **Diet adjustment**: Drink plenty of water and maintain a light diet, avoiding spicy foods and alcohol. 7. **Monitor symptoms**: If symptoms do not improve or worsen, seek medical attention promptly. Although facial dermatitis is common, proper care and treatment can quickly alleviate symptoms. We hope these suggestions help, and wish you a speedy recovery!
