Which of the following is NOT a primary skin type?

The classification of skin types typically revolves around primary characteristics that define the skin's inherent traits and behavior. Oily, dry, and combination skins are well-established as primary skin types.

Oily skin is characterized by an overproduction of sebum, leading to a shiny appearance and often associated with larger pores. Dry skin, on the other hand, is marked by a lack of moisture and a more textured, sometimes flaky surface. Combination skin exhibits traits of both oily and dry skin, often with an oily T-zone (forehead, nose, and chin) and dry or normal areas elsewhere on the face.

Reactive skin, however, is not categorized as a primary skin type. Instead, it refers to skin that is sensitive and prone to reactions from external factors like irritants, allergens, or environmental changes. This condition can affect any of the primary skin types and is seen more as a secondary characteristic of skin rather than a standalone type.

Identifying the differences between primary skin types and conditions like sensitivity is crucial for understanding skin care needs and tailoring treatments accordingly.
