Combination skin reacts to seasonal changes because humidity, temperature, and indoor heating affect oil production and moisture. Generally, spring and summer increase oiliness in the T-zone due to warmth and humidity, while fall and winter bring dryer air that can accentuate flakiness or tightness on the cheeks.
Typical seasonal patterns:
To manage seasonality, adjust products rather than overhaul your entire routine: switch to lighter, non-comedogenic moisturizers and oil-control products for summer, and introduce richer barrier-repair creams and hydrating serums in winter. Use sunscreen year-round, and consider a gentle exfoliator during transitional seasons to prevent buildup in oil-prone zones. Monitoring how your skin responds each season helps you fine-tune care and avoid overreacting to temporary changes.
