Acne Is Not Just for Teenagers
You thought acne would end with adolescence, but here you are – dealing with breakouts well into your 30s, 40s, or beyond. Adult acne is frustrating, confidence-eroding, and far more common than most people realise. At our practice in Zürich Seefeld, I treat adult acne not just as a skin problem but as a signal from your body that something internal needs attention.
Why Adults Get Acne
Hormonal imbalances: The most common driver, particularly in women. Excess androgens, high DHEA-S, or relative oestrogen-progesterone imbalances stimulate sebaceous glands and promote breakouts. Acne that flares before menstruation, around the jawline and chin, or after stopping hormonal contraception is almost always hormonally driven.
Insulin resistance: Elevated insulin increases androgen production and IGF-1 levels, both of which drive sebum production and skin cell proliferation. The link between diet, blood sugar, and acne is well established.
Gut dysfunction: The gut-skin axis is real. Dysbiosis, intestinal permeability, and SIBO can trigger systemic inflammation that manifests as acne. Many patients notice that their skin improves dramatically when gut health is addressed.
Stress: Cortisol and adrenal androgens (DHEA-S) both increase during stress, stimulating sebum production and inflammation. Stress-triggered acne is common in high-pressure professional environments.
Food sensitivities: Dairy is a well-documented acne trigger for many people, as it contains hormones and growth factors that stimulate sebaceous glands. High-glycaemic foods similarly worsen acne through insulin pathways.
Nutrient deficiencies: Zinc, vitamin A, vitamin D, and omega-3 fatty acids all play roles in skin health and inflammation regulation.
How We Investigate Adult Acne
I assess hormonal status (testosterone, free testosterone, DHEA-S, oestradiol, progesterone, SHBG), metabolic markers (fasting glucose, insulin, HbA1c), thyroid function, zinc, vitamin D, and inflammatory markers. For women, I evaluate the menstrual cycle pattern and screen for PCOS when relevant. Gut assessment may be indicated if there are concurrent digestive symptoms.
What We Do: Treating Acne From the Inside Out
Hormonal balancing: Addressing androgen excess through lifestyle modifications, targeted supplements (spearmint tea, saw palmetto, DIM), or when necessary, hormonal interventions.
Dietary optimisation: Reducing high-glycaemic foods and dairy, increasing anti-inflammatory foods, and identifying personal trigger foods.
Insulin sensitivity: Improving insulin sensitivity through diet, exercise, and targeted supplementation (berberine, inositol for PCOS-related acne).
Gut healing: Addressing dysbiosis and intestinal permeability to reduce the systemic inflammation driving skin breakouts.
Targeted supplementation: Zinc (30 mg/day), omega-3 fatty acids, vitamin D, and probiotics with evidence for skin health.
Topical and medical treatment: When needed, I prescribe appropriate topical treatments (retinoids, benzoyl peroxide, azelaic acid) or systemic medications, always as part of a comprehensive plan rather than as the sole intervention.
Conclusion
Adult acne is rarely just a skin problem – it is a reflection of internal imbalances that deserve investigation. By addressing hormones, blood sugar, gut health, and nutrition, most patients achieve significantly clearer skin without relying solely on topical treatments. If adult acne is affecting your confidence and quality of life, book a consultation at our practice in Zürich Seefeld.
