Common Skincare Mistakes that Dermatologists Don’t Make
From a clinical perspective, winter oily skin represents a barrier dysfunction problem, not an oil problem. Your sebaceous glands produce oil at relatively consistent rates year-round; it's your compromised moisture barrier creating the illusion of increased oiliness. When cold air and indoor heating damage your barrier, transepidermal water loss (TEWL) increases dramatically. Your skin responds by producing more sebum as protection.
