Acne is a common skin condition that is characterized by pimples, blackheads, and/or whiteheads on the face, chest, and back. These acne lesions usually form due to blocked pores where oil (sebum) from the skin's oil glands, also known as sebaceous glands, becomes trapped. This often occurs during puberty when hormone levels increase, causing the oil glands to produce more oil. This excess oil can then mix with dead skin cells and bacteria, leading to the formation of acne lesions. The other options, such as sweat, intestinal, and stomach glands, do not play a role in the development of acne and are therefore incorrect.
