Which of the following are common skin types?

The option indicating oily and dry skin types is correct because these are widely recognized categories when classifying skin types. Oily skin is characterized by excess sebum production, which often leads to a shiny appearance and can result in acne breakouts. Dry skin, on the other hand, may lack moisture and can feel tight or flaky. Both oily and dry skin types are fundamental concepts in esthetics, as they guide estheticians in tailoring skincare regimes and treatments to meet individual client needs.

Other skin types mentioned in other choices, while they may exist, do not represent the primary categories commonly used in esthetics. For instance, sensitive skin is not a type as much as it is a condition that can occur across various skin types, and mature skin pertains more to age-related changes rather than a skin type itself. Translucent skin is also not a standard classification in esthetics. Therefore, the distinction of oily and dry skin types is foundational to understanding and addressing the diverse needs of clients in skin care.
