Modern dermatological science increasingly recognises that chronic inflammatory skin conditions are frequently direct manifestations of gastrointestinal dysbiosis. Patients presenting with stubborn, adult-onset acne often request aggressive topical astringents, completely unaware that the primary catalyst lies within their daily diet.

High consumption of refined carbohydrates and certain dairy proteins can trigger a cascade of systemic inflammation, elevating insulin-like growth factor 1 (IGF-1) and subsequently upregulating sebaceous gland activity. Managing these complex dermatoses requires a sophisticated dual approach: utilising topical agents to control local bacterial proliferation while concurrently adjusting dietary habits to restore the intestinal microbiome.
