The “skin barrier” is part of our skin's top layer called the stratum corneum. It is made up of skin cells and a lipid interface that glues them together. It is also called the “brick-mortar” structure—skin cellsas the brick and lipid interface as the mortar. The lipid interface is made up of fatty acids, cholesterol and ceramides.
The skin barrier’s main roles are:
- Protecting your body from external stressors/microorganism
- Retaining water to keep your body and skin hydrated
When the protective barrier becomes damaged or impaired, it loses or becomes unable to hold on to the vital substances that keep skin cells intact, this leads to water loss and skin becoming more vulnerable to all external aggressors.
Some signs of a damaged skin barrier:
- Redness
- Dehydrated skin
- Dry, scaly skin
- Acne
- Tightness and itching
- Sensitive, irritated or inflamed areas
- Bacterial, viral, or fungal infections
It would be impossible to list every potential source of skin barrier impairment; everything from your genetic to your lifestyle can affect your skin barrier’s health.
Common causes of skin barrier damage:
- Alkaline cleansers (also over-washing)
- Over-exfoliating
- Pollution/UV radiation/Sun damage
- Misuse of actives like retinoids
