Technically speaking, acne and pimples are not the same disease. Acne is included in pimples because people who are not in puberty can also have acne. In medical terms, there is no such term as acne. The so-called acne clinically usually refers to pubertal acne, which is caused by overproduction of androgens, overproduction of sebaceous glands, infection by Propionibacterium acnes and hyperkeratosis of the hair follicle opening during puberty (usually between the ages of 10 and 25), and usually occurs on the face, chest and back. In addition to puberty, acne can also occur at any age. The onset of acne is not necessarily due to excessive androgen secretion, but may also be caused by other factors, such as poor sleep, dietary stimulation, environmental factors, and the use of certain medications. Patients are advised to go to the dermatology department of a hospital in a timely manner and use medication reasonably under the guidance of a professional doctor, rather than treating it on their own or listening to advertisements to avoid aggravating the condition.
