Final answer:
Oily skin is the type with a rough texture, blackheads, and enlarged pores, often linked to acne which is exacerbated by hormonal changes and can be influenced by diet.
Step-by-step explanation:
The skin type that has a rough texture with blackheads and enlarged pores is oily skin. This condition is often associated with acne, a common skin disorder where pimples, blackheads, nodules, or other skin lesions occur. The onset of puberty is a prime time for the development of acne due to the hormonal changes that increase the production of sebum. The overproduction of sebum can cause hair follicles to become clogged, creating an environment for bacteria to infect the pore, leading to acne lesions.
Maintenance of oily skin often involves a diligent skincare routine, which includes cleaning with a mild soap to help prevent the accumulation of excess oil and dirt. It is crucial to note that a diet high in refined sugars or carbohydrates, such as bread and chips, can also exacerbate acne.
