What are the four main skin types?

The four main skin types are indeed normal, oily, dry, and combination. Each of these categories provides a framework for understanding how skin behaves and what care it requires.

Normal skin is characterized by a balanced amount of sebum; it typically has a healthy appearance, neither too oily nor excessively dry. Oily skin tends to produce more sebum, which can lead to a shiny appearance, enlarged pores, and a higher likelihood of acne. Dry skin lacks moisture and can feel tight, rough, or flaky, often requiring hydrating products to restore balance. Combination skin exhibits characteristics of more than one type, usually showing oily areas along with dry or normal patches.

Other options may list skin types that are specific conditions or concerns—like sensitive or reactive skin—but they do not encapsulate the four foundational categories used to assess skin types in a general context. Understanding these main skin types is crucial for choosing the right products and treatments tailored to individual needs.
