Can I scratch or rub my face if it's allergic?

Generally, facial allergies should not be scratched. If necessary, it is recommended to seek medical attention promptly. Detailed explanation is as follows:

During facial allergies, the skin typically exhibits symptoms such as redness, swelling, and itching. Scratching the affected area with hands may further irritate the skin, worsening the allergic reaction. Additionally, hands may carry bacteria, which can easily enter the skin through scratches, leading to infection, skin damage, or even skin erosion, thereby increasing treatment difficulty and prolonging recovery time. Moreover, excessive scratching may compromise the skin's barrier function, making it more susceptible to external irritants and infections.

Scratching the allergic areas on the face can also lead to long-term effects such as skin pigmentation and scar formation. These consequences not only affect appearance but may also cause psychological stress to the patient. Therefore, when experiencing facial allergies, scratching with hands should be avoided to prevent worsening symptoms and aesthetic complications.

In daily life, it is important to avoid contact with known allergens, such as pollen, dust mites, and certain foods, to reduce the likelihood of allergic reactions.
