Which of the following best defines sensitive skin?

Sensitive skin is best defined as skin that reacts easily to products or environmental factors. This condition can manifest as redness, irritation, itching, or burning after exposure to certain substances, such as fragrances, alcohol, or harsh cleansers. Individuals with sensitive skin often have a compromised skin barrier, making it more vulnerable to irritants and allergens.

In contrast, skin that is prone to acne is characterized by breakouts caused by excess oil, clogged pores, and bacteria rather than responsiveness to products. Skin requiring frequent exfoliation typically indicates an accumulation of dead skin cells, which is not necessarily linked to sensitivity. Lastly, oily skin refers to a skin type characterized by excessive sebum production and shine, which is distinct from sensitivity. Understanding these distinctions is essential for skincare professionals in order to recommend appropriate products and treatments tailored to various skin types.
