Have you ever looked in the mirror and felt like your face was rounder than usual? You might be experiencing what is known as “moon face” or “cortisol face” – a condition in which the face appears swollen and puffy.

This health concern has been popping up on TikTok and Instagram, where users are sharing their experiences and seeking answers.

Moon face, medically known as moon facies, refers to the swelling that builds up on the sides of the face, giving it a rounder, puffier appearance.

While the condition is trending online for being stress-induced, medical professionals have long recognised this condition as a symptom of various health issues or medication side effects.

“The concept of cortisol face trending on social media as a common phenomenon for everyone experiencing stress is largely a myth,” says Dr Vijay Murthy, a doctor of functional medicine based in London, in the UK.

You might remember television sitcom Modern Family star Sarah Hyland’s social media posts about having a swollen face following her kidney transplants because of the steroid prednisone, a glucocorticoid medication mostly used to suppress the immune system and decrease inflammation.
