The mechanism described (stress → cortisol → water retention, fat redistribution, inflammation → puffy face) is real, but only at cortisol levels far beyond everyday stress — that's the clinical picture of Cushing's syndrome, a rare disease. Dermatologists and endocrinologists cited by GQ, Ohio State Health, and the University of Colorado are consistent: everyday stress isn't expected to produce a permanently round, puffy face; most temporary puffiness comes from sodium, alcohol, poor sleep, or allergies rather than a measurable hormone excess. The good news: the four fixes offered (sleep, movement, hydration, less processed food) are solid, well-supported general wellbeing habits, even though they won't "correct" a genuine medical cortisol elevation. Nothing here is dangerous or sells a product — it's an over-simplified explanation of something real but rare, presented as if it applies to any ordinary workday stress. Verdict: mixed — the cited mechanism is real, the scale attributed to everyday stress doesn't match the evidence.
