Why is using very hot water considered detrimental to skin barrier integrity during bathing?
Answer
It strips the skin of its natural oils more effectively than lukewarm water
The temperature of the water used for showering or bathing significantly impacts the skin's lipid barrier. Very hot water is highly effective at dissolving and washing away the essential natural oils (lipids) that protect the stratum corneum. These lipids are crucial for keeping the skin supple and preventing water evaporation. In contrast, using lukewarm water minimizes this aggressive stripping action, helping to preserve the protective matrix and reducing the post-wash feeling of tightness.
