The Skin Barrier, Stress and Sensitivity
Your skin barrier is the outer layer that helps keep moisture in and irritants out. Some studies link psychological stress to slower barrier recovery, which may help explain why dryness, stinging and flare-ups of conditions such as eczema and rosacea can show up during stressful periods.
The articles below cover how the barrier works, what stress may change, and gentle ways to support it.
What to know
- Dryness and sensitivity have many possible causes. Stress is only one of them.
- Fragrance-free moisturizers and gentle cleansing are commonly recommended first steps.
- See a clinician if skin is cracked, weeping, very painful, or not improving.
