Ah, the stratum corneum is that top layer of skin that's like the chaukhat of a house, no? A damaged barrier means that chaukhat is broken, letting irritants in and moisture out. People talk so much about acids making skin glow, but my own cheeks turned red and raw from over-exfoliating! Now I see that chasing that "glass skin" ruined my own strong barrier, yaar.
