Quick answer
Most "sudden sensitivity" is a damaged barrier, usually self-inflicted by too many actives. It repairs in weeks if you stop the cause.

The outermost layer of skin: cells held together by lipids — ceramides, cholesterol and fatty acids. It keeps water in and irritants out.
Signs it is damaged
Stinging from products that were previously fine. Tightness after washing. New redness, flaking, or sudden sensitivity. Products "not absorbing".
Repair, in order
1. Stop every active for at least two weeks
Acids, retinoids, vitamin C, scrubs, clay masks.
2. Cleanse once daily, gently, lukewarm
3. Humectant on damp skin, then an occlusive moisturizer
4. Add ceramides
They are the material the barrier is built from.
5. Reintroduce one active at a time, twice weekly
How long
Most barriers recover in two to four weeks. If redness persists beyond that, or is itchy and spreading, see a dermatologist — it may be eczema or rosacea.

Frequently asked questions
Does a damaged skin barrier feel different on oily versus dry skin?
Yes, oily skin often shows shiny, bumpy patches with sudden breakouts, while dry skin shows flaking and visible redness. Both need the same core fix: stop actives and rebuild with a gentle cleanser, humectant and moisturizer.
How do I know a barrier repair cream I bought in Bangladesh is genuine?
Check that the batch code on the tube matches the outer box, confirm the seal is intact, and watch for a texture or smell that feels off compared to what you expected. The free checker at theskinproof.com/product-checker can also confirm a batch code.
Can Dhaka's humidity make a damaged skin barrier worse?
Humidity alone usually does not damage the barrier, but combining sweat, hard tap water and over-cleansing in hot weather can slow recovery. Stick to one gentle cleanse a day and pat the skin dry instead of rubbing.
