How is skin type primarily determined?

Skin type is primarily determined by pore size, as this feature is closely linked to the activity of oil glands and the overall texture of the skin. Different skin types—such as oily, dry, combination, or normal—are categorized based on the size of the pores and how much oil is produced.

For instance, larger pores are typically associated with oily skin because the oil glands are more active, leading to a shiny complexion and possibly more acne. Conversely, smaller pores often characterize dry skin since there is less oil production, resulting in a tighter and possibly more sensitive skin condition.

The other factors mentioned, like skin color, elasticity, and the presence of acne, play significant roles in how skin appears and feels, but they do not primarily determine the skin type itself. Skin color can vary widely among all skin types and does not reflect the oil production level. Skin elasticity relates more to the skin's aging process and overall health rather than its classification. The presence of acne can occur across different skin types and may be more of a symptom than a determinant of skin type. Thus, pore size stands as the most crucial factor in identifying an individual's skin type.
