Which set lists four common skin types?

• A. Normal, dry, oily, and combination
• B. Balanced, dry, greasy, and mixed
• C. Normal, hydrated, oily, sensitive
• D. Normal, dry, combination, oily

Answer: (A)

Skin types describe how the skin produces oil and moisture, guiding how treatments and products should be chosen. The four standard categories most beauty therapists teach are normal, dry, oily, and combination. Normal skin has balanced oil and moisture, dry skin tends to feel tight or flaky due to low oil, oily skin produces excess sebum with shine and often larger pores, and combination skin is a mix, usually oily in the T‑zone and drier on the cheeks. This combination of terms is the one that matches the widely taught four categories, making it the best answer. Other options use terms like balanced, hydrated, greasy, mixed, or sensitive, which describe moisture status or conditions rather than the four primary skin types, so they don’t fit the standard classification.
