What it is
Adult hormonal acne concentrates on the lower face, jaw, and neck, tends to be deep and tender, and often coexists with dry skin elsewhere.
What's causing it
Relative androgen excess
As estrogen falls, testosterone and DHT influence sebaceous glands more strongly.
Insulin resistance
Raises IGF-1 and free androgens, worsening breakouts.
Cortisol
Stress increases sebum and inflammation.
Poor estrogen clearance
Sluggish detox pathways worsen the hormonal picture.
Nutrients commonly involved
What actually helps
- Rebalancing estradiol against androgens rather than treating skin in isolation
- Blood-sugar stability — the most underrated acne intervention in midlife
- Zinc, omega-3s, and a topical retinoid
