Pimple, also known as "acne", its pathogenesis is complex, but the cause of the pathology boils down to four factors: excessive keratinization of the hair follicles, excessive oil secretion, inflammation, Propionibacterium acnes infection. Pathologically, the occurrence and development of acne is roughly divided into the following four states:

The whole process is a gradual development: only the formation of the early stage of the naked eye can not see the formation of microcomedones, follicles sebaceous glands sebum and skin metabolites further accumulation of the formation of visible acne (Figure A and B), microcomedones and acne are non-inflammatory lesions, no redness, swelling, pain, some patients may be in the heat, localized pressure (such as wearing a mask). Some patients may experience localized itching when exposed to heat or localized pressure (e.g., wearing a mask). Inflammatory papules and pustules are formed when the lesions are further aggravated (e.g., Figure C), and if the inflammation is persistent and persistent, it may further develop into inflammatory nodules and cysts (e.g., Figure D). This is also the most serious manifestation, which will almost leave acne marks and scars.
