CAN AIR CONDITIONING (AC) DRY OUT THE SKIN ?
Yes. Water has a tendancy to go from the least to most concentrated environment. In this way, the water that is naturally contained in the skin has a tendancy to evaporate, going to into drier surrounding air. It is what is called transepidermal water loss, a phemonenon limited by the presence of the skin barrier that slows excessive evaporation. Air conditionning, which dries out the surrounding air, just like heating or wind, tends to accentuate this phenomenon. In this way, skin is dehydrated and even more so if the barrier function is compromised.
