Sensitive skin occurs when the skin’s protective barrier is compromised, making it more prone to irritation, redness, and reactions to external factors. This can happen due to a variety of reasons, including environmental stressors, harsh skincare products, climate changes, or even underlying skin conditions like eczema or rosacea. When the skin's natural barrier is weakened, it struggles to retain moisture and defend against pollutants, leading to heightened sensitivity. In some cases, genetic factors may also play a role, making certain individuals more predisposed to sensitive skin. Managing sensitive skin typically involves using gentle, hydrating products that restore the skin's protective layer and avoid triggers that could worsen irritation.
