← Human Body & HealthIf a hydrophobic pollutant disrupts the skin's lipid bilayer, which consequence follows regarding the stratum corneum barrier?
A)Enhanced antimicrobial peptide penetration
B)Increased trans-epidermal water loss✓
C)Upregulation of filaggrin production
D)Accelerated keratinocyte differentiation cascade
💡 Explanation
Disruption of the lipid bilayer compromises the skin's permeability barrier, because the intercellular lipids prevent excessive water loss. Therefore, increased trans-epidermal water loss occurs, rather than enhanced peptide penetration or altered differentiation, which involve different mechanisms.
