Seborrheic skin is defined by an overproduction of sebum, resulting in persistent oiliness, enlarged pores, and a tendency toward breakouts or irritation. This condition is driven by hyperactive sebaceous glands, often influenced by hormonal shifts—particularly androgens—as well as genetic predisposition.

A key contributor is Malassezia, a yeast that naturally lives on the skin but can proliferate in oily conditions, triggering inflammation and sometimes leading to seborrheic dermatitis. Environmental factors like heat, humidity, stress, and overly harsh skincare routines can further disrupt the skin’s balance. Rather than stripping the skin, effective care aims to regulate oil production, soothe inflammation, and restore the integrity of the skin barrier and microbiome.

Managing seborrheic skin requires a balanced approach. Over-cleansing or using drying products can worsen the problem by disrupting the skin barrier and triggering rebound oil production. Instead, effective care focuses on gently regulating sebum, calming inflammation, and supporting the skin’s microbiome to restore a healthy, balanced state.
