Cortisol, often referred to as the "stress hormone," does not directly darken skin. However, prolonged exposure to high levels of cortisol can lead to skin changes that may make it appear darker.
Here's how:
- Increased melanin production: Cortisol can indirectly stimulate the production of melanin, the pigment responsible for skin color. This can result in a darkening of the skin, especially in areas prone to hyperpigmentation, like the face, neck, and hands.
- Inflammation and acne: High cortisol levels can trigger inflammation, which can lead to acne breakouts and post-inflammatory hyperpigmentation (PIH), causing dark spots on the skin.
- Skin thinning: Chronic stress and high cortisol levels can thin the skin, making it more susceptible to sun damage and hyperpigmentation.
It's important to note that while cortisol can contribute to skin darkening, other factors play a significant role, including genetics, sun exposure, and certain medications.
If you notice significant skin darkening, it's crucial to consult a dermatologist to determine the underlying cause and discuss appropriate treatment options.
