What determines an individual’s skin type?

An individual’s skin type is predominantly determined by genetics. Genetic factors influence the skin’s natural oil production, moisture retention, thickness, sensitivity, and overall composition. For example, someone with a family history of oily skin is likely to inherit similar characteristics, while those from a lineage with dry skin may also experience that skin type.

Other factors do play a role in skin characteristics, such as diet, environment, age, and skincare routines, but these primarily affect the condition of the skin rather than its inherent type. For instance, environmental conditions like weather can influence moisture levels but do not change genetic predispositions. Similarly, while a skincare routine can alter the skin's appearance and health, it cannot change the fundamental genetic makeup that determines the skin type. Thus, genetics remains the primary determinant.
