When the skin barrier is compromised, the priority is usually not another strong active—it is reducing irritation and restoring hydration and barrier lipids.
The outermost layer of skin relies heavily on lipids such as ceramides, cholesterol and fatty acids to limit water loss and protect against external irritants.
Common signs that your routine may be overwhelming your barrier include:
- unusual tightness
- increased dryness
- burning from previously tolerated products
- flaking
- increased sensitivity
Which ingredients can help?
Niacinamide has evidence supporting stratum-corneum barrier function and reduced transepidermal water loss.
Panthenol has also been studied in moisturizers, with improvements in hydration and barrier recovery.
Ceramides are structural components of the skin barrier and can be useful when appropriately formulated into topical skincare.
Research also exists on particular Bifidobacterium lysates for reactive skin, although this should not be assumed to apply identically to every fermented cosmetic ingredient.
Breeze & Be’s Probiotic Day Cream contains Bifida Ferment Filtrate and niacinamide, alongside peptides and emollients.
Dr. Roy’s take:
When your barrier is struggling, simplifying the routine is often more useful than searching for another aggressive treatment.
