Understanding Your Skin Barrier
Stinging, tightness, sudden sensitivity to products you have used for years — usually a barrier problem, not a new skin type.

The outermost layer of skin works like a brick wall: cells are the bricks, lipids — ceramides, cholesterol, fatty acids — are the mortar. When the mortar thins, water escapes and irritants get in.
What a compromised barrier feels like
- Products that never stung now sting
- Tightness after cleansing that does not settle
- Redness that lingers
- Flaking alongside oiliness
- Breakouts that appear after adding an active
The usual causes
Over-exfoliation is first by a wide margin. Then harsh cleansers, too many actives at once, very hot water, and long stretches in air conditioning.
How to recover
Take everything out except three things:
1. A gentle cleanser
2. A bland moisturiser with ceramides
3. Sunscreen in the morning
No acids, no retinol, no vitamin C, no scrubs, no clay masks. Two to four weeks. It feels like doing nothing; it is the thing that works.
Reintroducing actives
One product. Twice a week. Two weeks. If skin stays calm, increase slowly. If it stings again, you moved too fast.
Prevention
Exfoliate two or three times a week at most, not daily. Keep one strong active in a routine rather than three. And when in doubt, moisturise — a barrier rarely suffers from too much of a plain cream.
