About
The stratum corneum functions as the primary permeability barrier, following a 'bricks and mortar' model — corneocytes (bricks) held together by lipid bilayers (mortar) composed of ceramides (~50%), cholesterol (~25%), and free fatty acids (~15%). Compromised barrier function underlies many dermatologic conditions.
Common Symptoms
Increased transepidermal water loss (TEWL)
Sensitivity to irritants
Stinging or burning with products
Redness
Dry and flaky skin
Increased susceptibility to infections
Risk Factors
- Filaggrin gene mutations
- Aging
- Over-washing with harsh cleansers
- Low humidity
- Nutritional deficiencies (essential fatty acids, ceramides)
- Topical retinoid use
- Atopic predisposition
