Which of the following is NOT a sign of sensitive skin?

Hydration is indeed not a sign of sensitive skin. In fact, sensitive skin is often characterized by a lack of moisture, leading to symptoms such as dryness, itching, and redness or erythema. Sensitive skin reacts more strongly to environmental factors, products, and even changes in temperature, which can exacerbate the signs of discomfort. When the skin is well-hydrated, it generally exhibits a barrier that helps to protect against irritants and reduces the likelihood of sensitivity. Thus, hydration is a healthy condition for the skin, contrasting with the indicators of sensitive skin, which highlight a compromised barrier function or irritation.
