Can egg white be applied to the face for allergies?
Generally, it is not recommended to apply egg white to the face during facial allergic reactions. If any abnormalities occur, prompt medical attention is advised. The detailed analysis is as follows:

Egg whites contain proteins and other components that may act as allergens. During an allergic reaction, the skin’s barrier function is weakened, and direct contact with egg white can trigger a more severe allergic response, such as spreading redness or intensified burning sensation. Moreover, raw eggs may carry microorganisms like Salmonella, increasing the risk of infection if applied to broken or damaged skin.
Theoretically, if allergy symptoms are mild and there is confirmed non-sensitivity to egg white, its astringent properties might temporarily reduce redness. However, actual effectiveness varies significantly among individuals. Even in cases of mild symptoms, some people may experience stinging sensations or develop new rashes after contact, and there is currently no solid scientific evidence supporting its efficacy.
During an allergic episode, avoid using unsterilized natural ingredients on the face. Instead, opt for medical-grade dressings with simple formulations or skincare products clinically proven to be safe. If symptoms persist or worsen, seek immediate medical evaluation to rule out possible infection.
