What the barrier does
The outermost layer of skin works like a wall: cells held together by lipids that keep water in and irritants out. When that structure is intact, skin feels comfortable, looks smooth and tolerates active ingredients well.
What weakens it
Over-cleansing, hot water, too many actives at once, sun, pollution, air conditioning and professional procedures all draw on the barrier. Oily skin can be barrier-compromised too; dehydration isn't the same as dryness.
How to support repair
Simplify. Cleanse gently, moisturise morning and evening, protect with sunscreen, and pause strong actives until skin is comfortable again. Then reintroduce them slowly, one at a time.
