What should you know about red face swelling?

Swelling may affect one area, both cheeks, the eyelids, or the lips. New cosmetics, skincare, medication, food, or an insect bite can cause an allergic or irritant reaction. Infection is more concerning when redness is warm, painful, tender, rapidly spreading, or accompanied by fever. Flushing and rosacea can cause facial redness and warmth, while swelling points to additional inflammation or another process. A red swollen face does not by itself establish the cause.

Stop any newly introduced product and gently rinse the area if a product may have touched it. Use a cool compress, keep the head raised, and avoid rubbing, heat, alcohol, and heavy makeup. Do not apply steroid or antibiotic creams near the eyes or lips unless a clinician has advised it. Photograph the change and record possible exposures, medicines, bites, pain, itch, and how quickly the swelling developed. Arrange assessment if it is not settling or the cause is unclear.

Call emergency services for trouble breathing, wheezing, faintness, confusion, or swelling of the tongue, throat, or lips. Seek urgent assessment for rapidly increasing swelling, severe pain, fever, eye pain, vision change, or difficulty opening the eye. Same-day medical advice is sensible for warm spreading redness or swelling after a bite, wound, injection, or procedure.

Could this be an allergic reaction, infection, or rosacea-related inflammation? Which exposures should I avoid? Is treatment safe around my eyes? What symptoms should prompt emergency care?
