🌿 FACT FRIDAY ✨
The Impact of Elevated Cortisol on the Skin Barrier
When stress levels are high, cortisol (the body’s primary stress hormone) can significantly affect skin health.
Key effects of elevated cortisol on the skin:
• Weakened barrier integrity
Cortisol disrupts the skin’s protective barrier, making it less effective at retaining moisture and defending against environmental stressors.
• Increased dehydration & dryness
A compromised barrier leads to increased transepidermal water loss (TEWL), resulting in tight, flaky or dehydrated skin.
• Heightened inflammation
Chronic stress keeps the immune system activated, promoting inflammation that can trigger redness, sensitivity and flare-ups of conditions such as eczema and rosacea.
• Slower repair & healing
Elevated cortisol can slow cell turnover and wound healing, meaning breakouts, irritation and skin damage take longer to resolve.
• Increased oil production & breakouts
Cortisol stimulates the sebaceous glands, increasing sebum production and contributing to congestion and acne.
🌿 Supporting the Skin When Stress Is High
• Focus on hydrating, barrier-supportive skincare
• Avoid over-exfoliation and harsh actives
• Use gentle cleansers to protect the skin barrier
• Prioritise sleep, hydration and regular movement
• Incorporate stress-reducing practices such as meditation, massage or holistic treatments
Healthy skin isn’t just about products — it’s about supporting the nervous system too 💚
