Acne and the different severities of acne has generally affected all of us in one way or another. From blackheads to pustules, pimples, inflammation, nodules, cysts, papules, white heads and then to what is actually causing your acne - the possibilities are variable to each individual.
Acne is a combination of inflammation with the infection of a pore. Within the pore you tend to see a build up of dead skin cells which have failed to complete the natural skin cell turnover. Each pore is connected to a sebaceous gland, which produces an oily substance called sebum. Extra sebum can plug pores, causing the growth of a bacteria known as Propionibacterium acnes, or P. acnes. Your white blood cells attack P. acnes, leading to skin inflammation and acne.
