What is the difference between allergic skin and sensitive skin?

The differences between allergic skin and sensitive skin are mainly reflected in their causes, symptoms, and treatment approaches. 1. **Causes**: Allergic skin is a skin type primarily triggered by exposure to allergens such as food, pollen, and dust mites, leading to increased skin vascular permeability. In contrast, sensitive skin is a constitutional condition, potentially related to genetic factors and impaired skin barrier function, primarily manifesting as an overreaction to external stimuli. 2. **Symptoms**: Symptoms of allergic skin include itching, localized redness, and hives. Sensitive skin may present with dryness, enlarged pores, redness, stinging, or warmth; in severe cases, flaking and erythema may occur. 3. **Treatment**: The key to managing allergic skin is avoiding allergens and using antiallergic medications when symptoms are severe. For sensitive skin, symptom relief involves improving lifestyle habits, avoiding irritants, using mild and non-irritating skincare products, and focusing on restoring the skin barrier function. If you have any concerns, please consult a healthcare professional.
