Understanding your skin barrier

The outermost layer of skin behaves like a wall: cells held together by lipids that keep water in and irritants out. When that wall is intact, skin tolerates weather, products and treatment. When it is not, everything stings.
Barrier damage usually happens gradually. Frequent exfoliation, multiple active ingredients started at once, very hot water and long gaps between moisturising all contribute. The result is often mistaken for sensitive skin, when it is really a temporary, reversible state.
In clinic, we usually pause actives, simplify the routine to a gentle cleanser, a barrier-supporting moisturiser and daily sunscreen, and then reintroduce treatment slowly. Recovery is often faster than people expect.
If irritation persists despite a simplified routine, it is worth a dermatology consultation. Conditions such as eczema, contact allergy and rosacea can look similar and are managed differently.
