You should not use aloe vera gel for facial allergies. Facial allergies are usually caused by certain ingredients in cosmetics or other external factors, such as pollen, sun exposure, seasonal changes, etc., which stimulate skin cells and cause skin cells to produce antibodies, resulting in allergies. The use of aloe vera gel at this time can aggravate the allergic reaction and cause adverse consequences. Symptoms of facial skin allergy are usually itching, which may be accompanied by redness, dry flakes, blisters or crusting of lesions and exudate. Occasionally, tightness, numbness and swelling of the face may occur. In rare cases, allergic reactions can even be life-threatening, such as anaphylaxis. Facial allergies should be treated promptly and medication should be administered according to medical advice. Firstly, allergens need to be found for targeted prevention; secondly, anti-allergy medications such as loratadine and cetirizine should be chosen for treatment, and topical medications such as 3% boric acid solution can be used for local wet compresses. For symptoms of blistering or exudation, use Ravnol solution for wet compresses and avoid applying hormonal drugs as much as possible. Wash your face with lukewarm water, use mild cleansing products, moisturize well, and avoid using irritating products such as fruit acids, exfoliators, and alcohol-based lotions. Work and rest regularly, ensure sufficient sleep and proper exercise, and keep your mood relaxed.
