What role does Cortisol play in Haut?

Cortisol, the body's primary stress hormone, directly and indirectly affects the skin. Acutely, it increases sebum production and can exacerbate inflammation – a well-documented mechanism in stress-related acne (human-strong). Chronically elevated cortisol impairs collagen synthesis, weakens the skin barrier, and accelerates aging. It also delays wound healing. Genetic variants in NR3C1 (glucocorticoid receptor) or CRHR1 may modulate individual sensitivity, but effect sizes are small and consumer DNA tests currently lack predictive power for cortisol-driven skin issues (evidence: unclear). MyBody-X does not offer a specific cortisol-skin analysis. Practical measures like stress reduction, adequate sleep, and an anti-inflammatory diet are more impactful than genetic testing. For persistent skin concerns, consult a dermatologist.
