Acne is a dermatosis characterized by different stages of inflammation that affects the hair follicle and the sebaceous gland. Acne is aided by hyperkeratosis, which is a phenomenon where the skin responds to the irritation caused by the sebum, the composition of which has been modified by the bacteria in the hair follicle.
Acne-prone skin is generally impure skin that produces a fair amount of sebum.
Due to excess sebum, the pores in this type of skin can sometimes clog and fill with sebum and small fragments of dead epithelial cells.
This is how a blackhead is created, which can then transform into the classic “pimple” (pustule), or a papule can appear.
Acne-prone skin generally has localized areas that are more shiny, such as the T area (forehead and nose) or areas with larger sebaceous glands.
