Research into the relationship between psychological stress and dermatological health has progressed from observing physical symptoms to identifying specific biological mechanisms.

Initial observations indicated that psychological stress can compromise the skin barrier, leading to moisture loss, dehydration, increased sensitivity, and the worsening of acne. These effects often manifest as a combination of oily appearance, redness, itching, and tightness.

Subsequent findings from researchers at Fudan University have identified a specific neural pathway connecting brain stress to skin inflammation. Utilizing mouse models and analysis of patients with atopic dermatitis, the study mapped how sympathetic neurons, specifically Pdyn+, act as a direct link between the brain and the skin’s immune system. When activated by stress, these neurons release signals that attract eosinophils, which trigger redness and itching. Experimental results showed that blocking these neurons could prevent stress-induced inflammation.
