What fundamental process leads to skin dryness medically termed xerosis?
Answer
The skin loses too much water or essential natural oils faster than it can retain them
Skin dryness, or xerosis, fundamentally results from a disruption in the skin's moisture balance. This imbalance occurs when the rate at which the outermost layer, the stratum corneum, sheds water or its essential protective lipids exceeds the rate at which the body can replenish or retain those components. The barrier function relies on keeping these vital components intact; when this protective mechanism fails, excessive transepidermal water loss occurs, leading to the clinical signs of dryness.
