    Sensitive skin can stem from various factors, making it a complex issue to pinpoint. One primary cause is an impaired skin barrier. The skin’s outermost layer, known as the stratum corneum, acts as a protective barrier against environmental aggressors. When this barrier is compromised due to genetics, harsh skincare products, or environmental factors like pollution or UV radiation, the skin becomes more susceptible to irritation and sensitivity.

    Another common cause is inflammation. Skin inflammation can result from allergies, reactions to certain ingredients in skincare products, or underlying skin conditions like eczema or rosacea. Inflammation triggers the release of pro-inflammatory molecules, leading to redness, itching, and a heightened sensitivity response.

    Additionally, lifestyle factors such as stress, hormonal changes, diet, and climate can contribute to sensitive skin. Stress, for instance, can weaken the skin’s defenses and exacerbate existing sensitivities. Hormonal fluctuations, especially during puberty, pregnancy, or menopause, can also influence skin sensitivity. Dietary choices, particularly consuming inflammatory foods or lacking essential nutrients, may impact skin health, while extreme climates or pollution can further aggravate sensitive skin conditions.
