Acne in Adults: Hormonal and Lifestyle Factors
By Dr. Navaneeth K. Unni•Published on 2026-07-01•Patient Group: Adults
Clinical Overview & Pathophysiology
Adult acne is different from teenage acne. Often located on the lower face, jawline, and neck, it is closely linked to hormonal fluctuations, chronic stress, and inflammatory dietary habits.
Key Clinical Facts & Indicators
- Androgen Sensitivity: Excess sebum production caused by fluctuations in testosterone or insulin.
- Gut-Skin Connection: Diets high in refined sugar and dairy raise insulin, triggering skin inflammation.
- Chronic Stress: High cortisol levels stimulate adrenal glands to produce more pore-clogging sebum.
- Cosmetic Congestion: Heavy makeup or comedogenic skincare blocking pores.
Lifestyle & Nutritional Guidelines
Address adult acne by adopting a low-glycemic diet and limiting dairy. Use non-comedogenic skincare products. For hormonal acne related to PCOS, check our Women's Health guidelines and use our Diet Planner.
Frequently Asked Questions
Q: Why does stress trigger acne breakouts?Stress releases cortisol and androgens, which stimulate the sebaceous glands to produce excess sebum, leading to blocked pores.
Q: How does dairy contribute to acne?Dairy contains growth hormones and can increase IGF-1 levels, which promotes sebum production and follicular inflammation.
