On TikTok, the “cortisol face,” or a puffy face caused by stress, has become the bane of beauty influencers. But behind this trendy concept, there is a more precise medical reality. Dr. Gérald Kierzek explains what a “cortisol face” really is (and it has nothing to do with beauty).
They are there, tracking down the slightest change, the slightest subtle swelling of their face in front of the camera. On Tik Tok, beauty influencers do everything to drain their face, and avoid what is called “cortisol face”, a face puffy from stress. But are they right?
The “cortisol face”, Tik Tok version
The obsession gave birth to this word, cortisol face or “moon face”, two expressions that we now willingly share on social media to talk about our skin and face. On TikTok, the expression refers to a puffy face, which is generally attributed to too much stress in one’s life. Cortisol is in fact the body’s main stress hormone, regulated by the adrenal glands. But there is no medicine in their testimonies: what interests the influencers is the appearance of their face.
On the lookout for the slightest feature that is a little too round, they exchange their best tips for regaining a sculpted face: gua sha, massage, hours of sleep, or even relaxation… This “cortisol face” is ultimately a good excuse to take care of yourself.
Only a serious health condition will change your face
The medical version is another matter. Consulted on the subject, Dr. Gérald Kierzek, medical director of Doctissimo, wishes to re-establish a little truth.This ‘cortisol face’ is a term popularized on social media to describe the symptoms of facial swelling and puffiness linked to high cortisol levels.” In times of stress, he grants, the body increases cortisol production, which can lead to water retention and fat deposits in the face, giving a rounder, puffier appearance.
“But in reality, only chronically elevated levels of cortisol can lead to more pronounced physical changes, such as the development of what is called “moon face.” Even everyday stress does not give this appearance; it takes real diseases such as Cushing’s syndrome or prolonged use of corticosteroids. Although stress can cause fluctuations in cortisol, they are insufficient to cause these symptoms.”
If your face is swollen, see a doctor (not Tik Tok)
Therefore, the term cortisol face seen on social media would be quite inaccurate. But if you notice persistent changes in the appearance of your face or other symptoms associated with high cortisol levels, such as unexplained weight gain, sleep disturbances, or skin problems, it is advisable to consult a healthcare professional. “Tests may be needed to assess your cortisol levels and determine the cause,” concludes the doctor.
