Final answer:
The presence of obvious pores usually indicates areas of oily skin, which can lead to acne due to blocked pores by oil, bacteria, and dead skin.
Step-by-step explanation:
When determining skin type, the presence of obvious pores indicates areas of oily skin. Each pore on your skin is the opening to a follicle, composed of a hair and a sebaceous gland that releases sebum. In cases where there is overproduction of sebum, it can lead to skin concerns like acne, which occurs when these pores become blocked by oil, bacteria, dead skin, and dirt. Cleaning your skin daily with a mild soap to remove excess oil and dirt can help prevent acne, a common skin disorder characterized by pimples, blackheads, nodules, or other skin lesions that occur when bacteria infect sebum-clogged pores.
