Which skin type may require the most hydration?

Dry skin is characterized by a lack of moisture and oil, which can lead to a dull and rough texture. This skin type often shows signs of dehydration more prominently, such as flakiness, tightness, and even irritation. People with dry skin typically have compromised natural moisture barriers, making it essential for them to use products that provide ample hydration.

In contrast, oily skin already produces excess oil, which can contribute to a shiny appearance. Combination skin has both oily and dry areas, while normal skin tends to be well-balanced, requiring less intensive hydration than dry skin. Therefore, among the options presented, dry skin indeed requires the most hydration to restore balance and maintain a healthy, supple appearance.
