Final answer:
Acne is a skin condition that presents papules, pustules, and sometimes scars mostly on the face, neck, and forehead due to clogged hair follicles. It usually results from hormonal changes that increase sebum production, leading to bacterial infection and subsequent inflammation.
Step-by-step explanation:
Papules and papulopustules are types of skin lesions associated with acne, characterized by small raised bumps on the skin which can evolve into pus-producing lesions. Accompanied by fine white scales and hyper-pigmented macules, which are areas of discoloration that appear where previous acne lesions have ruptured. These symptoms are primarily located on the inferior chin, neck, and forehead, which are areas rich in sebaceous glands.
Acne is a common skin disorder that affects many people, especially during puberty but can persist into adulthood. It occurs when hair follicles become clogged by shed skin cells and sebum, leading to various types of lesions including, comedones, which can be both non-inflammatory (whiteheads and blackheads) and inflammatory (pustules and nodules). Acne can cause skin discoloration or lead to scarring, particularly when not treated properly.
Acne lesions are often itchy or sore, and when they resolve, the skin may be left with areas of hyperpigmentation or scarring. The condition is typically triggered by hormonal changes that stimulate excess sebum production, which mixes with dead skin cells to block pores, creating an environment conducive to bacterial infection.
