Myths vs facts: Cortisol and skin. A common myth is that cortisol alone causes acne. In reality, elevated cortisol can increase sebum production, but acne is multifactorial (bacteria, keratinization, genetics). Another myth: cortisol permanently ages the skin. Fact: chronically high cortisol degrades collagen and elastin, leading to wrinkles and thinner skin – supported by studies (e.g., in Cushing syndrome). However, effects from everyday stress are moderate and modifiable by lifestyle (sleep, diet). The notion that topical corticosteroids are always dangerous is nuanced: short-term use is anti-inflammatory, but long-term use risks skin atrophy and telangiectasias. The MyBody-X context provides no specific data on cortisol and skin; this answer relies on general medical evidence. Conclusion: cortisol affects skin, but relationships are complex and not monocausal. Beware of exaggerated marketing claims that blame stress alone for skin issues.
