[Dermatology and Venereology] How should combination skin be cared for?

Mixed skin is a common dermatological condition characterized by simultaneous oily and dry areas on the face—typically with increased sebum production in the T-zone (forehead, nose, and chin) and drier, sometimes flaky or tight-feeling skin on the cheeks and periorbital regions. This variation arises from regional differences in sebaceous gland density, hormonal influences, environmental exposure, and genetic factors.

Effective management focuses on balancing hydration and sebum control without over-drying or over-stimulating the skin. Begin with a gentle, non-comedogenic, pH-balanced cleanser used once or twice daily—avoiding harsh sulfates or alcohol-based products that can disrupt the skin barrier and trigger compensatory oil production. Follow with targeted application of lightweight, oil-free moisturizers to dry zones and mattifying, niacinamide- or salicylic acid–containing formulations for the T-zone.

Sun protection is essential: use a broad-spectrum, non-comedogenic SPF 30+ sunscreen daily, preferably in a fluid or gel-based formulation to minimize pore congestion. Incorporate active ingredients thoughtfully—low-concentration retinoids (e.g., adapalene) may improve texture and regulate sebum when introduced gradually, while hyaluronic acid supports hydration across all zones. Avoid physical scrubs or excessive exfoliation, which can compromise barrier integrity; instead, opt for mild chemical exfoliants (e.g., low-percentage lactic or mandelic acid) no more than 1–2 times weekly if tolerated.

Consistency and individualization are key: monitor response closely and adjust based on seasonal changes, stress levels, or hormonal fluctuations. If persistent redness, inflammation, acne, or barrier dysfunction develops—or if over-the-counter regimens prove ineffective—consult a board-certified dermatologist for personalized assessment and potential prescription therapies such as topical azelaic acid, low-dose oral contraceptives (in eligible individuals), or isotretinoin in severe cases.
