If a person's sebum production decreases substantially while living in a cold, dry climate, which consequence follows regarding skin integrity?

💡 Explanation

Decreased sebum results in reduced lipid content on the skin surface, because sebum creates a hydrophobic barrier that minimizes water evaporation. Therefore, trans-epidermal water loss accelerates, rather than being offset by keratinocyte activity or related to collagen changes or melanin synthesis.
