Does your oily skin feel dry in winter? You are not alone. The seasons affect moisture levels in all skin types.
Seasonal changes are more noticeable in cold climates but warm, humid, climates also have fluctuations in moisture levels.
Trans epidermal water loss (TEWL) is the official name for loss of water through the skin to the surrounding atmosphere via the evaporation process. TEWL is a process which can take us by surprise, substantial dehydration sometimes occurs before a person realizes what is happening.
TEWL is affected by environmental factors such as humidity, temperature, the time of year and the moisture content of the skin. Your first line of defense is to stay properly hydrated internally.
Our skin is most dehydrated from December through March. Seasonal changes during April, May and June help the skin re-hydrate. The cycle of moisture loss begins again in July and continues until our skin is at its most dehydrated in December.
