What is the term used for prolonged exposure that can lead to skin sensitivity?

The term that describes prolonged exposure leading to skin sensitivity is overexposure. When the skin or body is subjected to certain substances, particularly irritants or allergens, for an extended period, it can become overly sensitive. This concept is crucial in nail care and beauty practices, as professionals must understand that ingredients in products may be safe in small amounts or brief contact but can yield adverse effects when there is frequent or continual exposure.

In contrast, the other terms have specific meanings that do not align with prolonged exposure in this context. An allergy refers to an immune response to a substance, dermatitis is a general term for inflammation of the skin, and hypersensitivity indicates an exaggerated allergic response. While these conditions can also result from exposure to products, the term that specifically emphasizes the effect of extended exposure is overexposure.
