Which type of skin is sensitive to products due to a compromised barrier function?

1. Dry skin

2. Normal skin

3. Oily skin

4. Dehydrated skin

The correct answer is: Dry skin

Dry skin is often characterized by a compromised barrier function, which can make it highly sensitive to various products. This sensitivity arises because the outermost layer of the skin, known as the stratum corneum, is often unable to retain moisture effectively in dry skin. When this barrier is compromised, it can lead to increased transepidermal water loss, making the skin more vulnerable to irritants and allergens. Individuals with dry skin may experience reactions such as redness, itching, or stinging when using certain skincare products, particularly those that contain fragrance, alcohol, or harsh ingredients. Because of this heightened sensitivity, it is crucial for people with dry skin to choose gentle, hydrating products that support barrier repair and help retain moisture. In contrast, normal skin has a well-functioning barrier, while oily skin may have a different composition that offers a degree of protection against sensitivity. Dehydrated skin, although it can be sensitive, typically refers to a lack of water content rather than an inherent problem with the barrier function itself. Therefore, recognizing dry skin as the type that experiences heightened sensitivity due to barrier compromise is essential for effective skincare management.
