Dry indoor air and winter winds, hot summer weather and sun exposure – every season brings a different set of challenges to the skin. In winter months, skin becomes more susceptible to irritation caused by cleansing products, while its barrier function and moisture regulation become compromised. As spring begins and the days grow longer, people spend more time outdoors and the need for UV protection increases.

Facial skin is generally oilier in the summer. UV rays cause photo-aging and thickening of the stratum corneum, and activities like swimming lead to cutaneous dehydration. When the leaves begin to turn and autumn approaches, the skin needs support regenerating after the effects of summer. Temperatures decline, the stressors of winter return and the cycle begins again.
