The #1 mistake people make that damages the skin barrier is over-cleansing or over-exfoliating, often with harsh scrubs or foaming cleansers that strip natural oils. For Indian skin—whether oily, dry, sensitive, or acne-prone—I recommend barrier-repairing routines built around gentle, pH-balanced cleansers, ceramide-rich moisturizers, and hydrating ingredients like hyaluronic acid and niacinamide. For acne-prone skin, lightweight gel-based formulations with niacinamide work well, while dry or sensitive types benefit from richer creams with ceramides and fatty acids. A key myth to avoid is that 'more exfoliation equals clearer skin'—in reality, over-exfoliation weakens the barrier and worsens sensitivity. Barrier repair is about consistency, hydration, and protection, not aggressive treatments.
