← Human Body & HealthWhy does excessive hyaluronic acid degradation in dermal tissue impair skin barrier function?
A)Reduced melanocyte UV protection occurs
B)Keratinocyte differentiation rates decline
C)Diminished moisture retention compromises stability✓
D)Collagen synthesis accelerates excessively instead
💡 Explanation
Hyaluronic acid's primary function is retaining water, because it binds to numerous water molecules in the extracellular matrix, and its degradation reduces the skin's ability to maintain hydration; therefore, the skin barrier function is impaired, rather than protection from melanocytes or affecting collagen synthesis directly.
