2. Barrier Damage Increases Sensitivity to Products

When the skin barrier is compromised, irritants and allergens can penetrate more easily, leading to heightened sensitivity during makeup application. This may manifest as redness, burning, or stinging sensations, especially when introducing new products or formulas.
People with resilient skin typically tolerate cosmetics well, while those with weakened barriers often struggle with discomfort and visible reactions. According to the Mayo Clinic, barrier dysfunction increases susceptibility to external irritants, making it crucial to prioritize barrier repair before makeup for a comfortable, flawless finish.
