Which type of skin condition is indicated by excessive oil production?

Oily skin is characterized by excessive oil production from the sebaceous glands, which can lead to a shiny appearance and may cause issues such as acne and enlarged pores. Individuals with oily skin often find that their skin feels greasy and may be more prone to breakouts and blackheads due to the accumulation of oil and dead skin cells that can clog pores.

This skin type typically has a thicker texture and a more pronounced pore size, particularly in the T-zone (forehead, nose, and chin). The increased oil production can be influenced by various factors, including hormonal fluctuations, genetics, and environmental conditions.

In contrast, dry skin lacks sufficient oil and moisture, resulting in a rough, tight feel and sometimes leading to irritation or flakiness. Normal skin has a balanced oil and moisture level, creating a healthy skin barrier without excessive shine or dryness. Combination skin exhibits characteristics of both oily and dry skin in different areas of the face, often being oily in the T-zone while dry or normal on the cheeks.

Thus, the defining feature of oily skin is its excessive oil production, which distinguishes it from the other skin types.
