Oily skin is characterized by excess oil production, often resulting in a shiny appearance and enlarged pores. Individuals with this skin type typically experience an overproduction of sebum, the natural oil produced by sebaceous glands. This can lead to various skin issues, such as acne and blackheads, as the excess oil can trap dirt and bacteria in the pores.

In contrast, dry skin lacks sufficient moisture and can feel tight or rough. Normal skin has a balanced level of oil and moisture, while sensitive skin can react to various stimuli, leading to redness or irritation. Understanding these differences helps in selecting appropriate skincare products and treatments tailored for each skin type.
