What should I do if my face becomes red, itchy, and allergic after using cosmetics?

In general, facial redness and itching caused by allergic reactions to cosmetics can be managed through measures such as discontinuing the use of cosmetics, washing the face, cold compresses, dietary adjustments, and medication. If discomfort persists, it is advisable to seek medical attention promptly. Specific approaches are as follows:

1. Discontinue use of cosmetics

If you have an allergic constitution or are sensitive to certain ingredients in cosmetics, stop using them immediately to prevent worsening of the allergic reaction.

2. Wash the face

If the cosmetic product contains irritating ingredients, wash the affected area with running lukewarm water to reduce skin irritation and help alleviate symptoms.

3. Cold compress

Apply a cold pack or ice bag wrapped in a clean cloth to the affected area to constrict local capillaries and relieve itching.

4. Dietary adjustment

Maintain a balanced diet and avoid spicy or irritating foods such as chili peppers and hot pots. Also avoid allergenic foods such as seafood and lamb, which may exacerbate allergic symptoms.

5. Medication

If allergic symptoms are severe, antiallergic medications such as loratadine tablets, ebastine tablets, or calamine lotion may be used under a doctor's guidance.

In daily life, ensure adequate rest and sufficient sleep, avoid staying up late, and engage in moderate outdoor activities such as walking or light exercise, which may aid recovery.
