Oily skin is characterized by an overproduction of sebum (natural oils) from the sebaceous glands, which can lead to a shiny appearance, clogged pores, and an increased likelihood of breakouts. This skin type often has a thicker texture and enlarged pores, particularly in the T-zone (forehead, nose, and chin). Oily skin can be caused by genetics, hormonal changes, stress, or environmental factors. While oil is essential for skin health, excessive sebum can lead to clogged pores and acne. The key to managing oily skin is finding a balance with gentle, oil-controlling products that hydrate without over-drying.
