Sensitive skin is defined by its heightened reactivity to various stressors, including certain skincare products. The degree of sensitivity can range from mild irritation in response to these stressors to more pronounced issues such as persistent redness, itching, and discomfort. Importantly, sensitivity may not always manifest visibly; it can also be about how the skin feels rather than what is immediately observable. Individuals with sensitive skin require extra care and should choose products that are gentle and soothing to avoid triggering adverse reactions.
