The stress hormone cortisol has a profound impact on more than just your emotional state. When you're stressed, cortisol levels rise, triggering physiological responses that can directly affect your skin. Elevated cortisol can lead to increased oil production, inflammation, and exacerbation of existing skin conditions, manifesting as acne, eczema, or psoriasis. Understanding this connection between stress and skin health is crucial for maintaining a clear, vibrant complexion and overall well-being.
