Pimples are usually inflammatory papules, pustules, etc. Both pimples and acne belong to acne, and they are in different stages of occurrence. Pimples usually belong to the initial stage of acne, while the formation of pimples is triggered by the inflammatory infection of acne.
Acne is mainly caused by hyperkeratosis at the opening of the sebaceous glands of the hair follicles, resulting in localized narrowing and occlusion, and overproduction of sebum that cannot be discharged, leading to localized formation of pimples. Acne is also classified into whiteheads and blackheads: the former are atretic and appear to have raised whiteheads that are more difficult to extrude; the latter are formed when whiteheads are open and come into contact with air oxidation.
If acne is not treated in time, Propionibacterium acnes at the follicular sebaceous gland unit proliferates locally, leading to inflammation, which leads to the formation of inflammatory papules, pustules, etc., which are commonly known as pimples. Inflammatory papules have a reddish, tough surface and contain no pus, while pustules are elevated and contain cloudy gel, and may be surrounded by redness, swelling, and pain.
What people call “pimples” and “acne” are clinical manifestations of different stages of acne. It is recommended that patients with acne or pimples go to a professional hospital in time and actively cooperate with doctors for standardized treatment.
