Final answer:
Acne is a disorder involving the clogging of follicles that leads to infection and inflammation. It is characterized by redness, pimples, and sometimes scarring, often triggered by hormonal changes and excess sebum production.
Step-by-step explanation:
A disorder in which follicles become clogged, resulting in infection with redness and inflammation is known as acne. Acne is a common skin disorder that involves the clogging of pores which can lead to infection and inflammation. Acne typically occurs on areas of the skin with high concentrations of sebaceous glands such as the face and back. This skin disturbance can occur in adolescents, often due to hormonal changes, but can also affect infants and continue into adulthood.
Excessive secretion of sebum by these glands can plug hair follicles. The sebum, together with keratin, forms a plug that is initially white and, upon oxidation, turns black. The clogging creates an ideal environment for acne-causing bacteria (like Propionibacterium and Staphylococcus) to thrive, leading to inflammation, redness, pimples, nodules, and potentially scarring. The immune system's response to this bacterial infection results in the visible symptoms of acne, such as swelling and the formation of pus-filled lesions.
