Detailed answer

Redness and sensitivity can be caused by multiple factors. Inflammation is a common cause, triggered by factors such as irritation, allergies, or skin conditions like rosacea. When the skin's protective barrier is compromised, it becomes more susceptible to redness and sensitivity. This can occur due to using harsh skincare products, over-exfoliation, or excessive sun exposure. Certain skin conditions like eczema or psoriasis can also contribute to redness and sensitivity. Additionally, environmental factors such as pollution, cold weather, and wind can exacerbate these issues. It is important to identify and address the underlying cause of redness and sensitivity for effective treatment and prevention.
