Think of your skin barrier as the studio door. While it’s closed and sealed, everything inside stays calm. Leave it propped open, and the weather gets in.
Signs the door is open
Sudden stinging from products that never stung. Tightness an hour after moisturising. A shiny-but-dehydrated look that no serum seems to fix. That’s not a product problem; it’s a barrier problem.
The repair kit is short: a cream with ceramides, lukewarm water instead of hot, and a two-week pause on every acid and scrub. The glamorous ingredients can wait — they work better through a closed door anyway.
