What is a characteristic of sensitive skin?

Sensitive skin is characterized by its propensity to react negatively to various products, environmental conditions, or certain skincare treatments. Individuals with sensitive skin often experience irritation, redness, burning, or stinging sensations when exposed to certain ingredients in skincare products, extreme weather conditions, or even harsh fabrics. This sensitivity indicates that the skin's barrier function may be compromised or that there is an underlying condition, influencing how the skin responds to stimuli.

The other choices do not accurately capture the nature of sensitive skin. For example, having resistance to all products does not align with the experience of sensitivity. Additionally, sensitive skin can show signs of aging like any other skin type, and it typically requires more careful attention and specialized products rather than minimal care. This context reinforces why the characteristic of being easily irritated is the defining feature of sensitive skin.
