Short-Term Effects of Stress on Skin: Dryness, Acne, Sensitivity, and Management

Acute stress activates the HPA axis and sympathetic nervous system, releasing cortisol, catecholamines, and neuropeptides (substance P, CRH) that directly affect skin:

1. Barrier disruption: Cortisol ↓ lipid synthesis (ceramides, cholesterol) → ↑ TEWL → dryness, flaking.
2. Increased sensitivity: Mast cell degranulation, nerve ending sensitization → reactivity to products, temperature.
3. Acne flare: Cortisol ↑ sebocyte lipogenesis; CRH ↑ sebaceous gland activity → comedones, inflammatory papules.
4. Periorbital changes: Vasodilation + lymphatic stasis → dark circles, puffiness.
5. Inflammatory dermatoses: Stress exacerbates psoriasis, atopic dermatitis, rosacea, seborrheic dermatitis via neuroimmune crosstalk.

Management

• Gentle, barrier-supportive skincare (ceramides, hyaluronic acid).
• Stress reduction: CBT, mindfulness, sleep hygiene, exercise.
• Short-term topical steroids/calcineurin inhibitors for flares (dermatologist-guided).
• Avoid known irritants during high-stress periods.

Chronic stress accelerates aging (telomere shortening, MMP upregulation, collagen degradation).
