Acne is due to a regular skin bacteria called P. acnes, everybody has this bacteria in skin, but some strains of the bacteria are known to cause acne.
It is unknown why some ppl have more of this strains of bacteria making them prone for acne. The bacteria will clog the pores due to being happier in anaerobic environments, and feast on the sebum the pore produces. This clogged pores can turn into cystic zits from a immune system response, basically your body recognizes an infection and attacks it. It is not known the exact mechanism why this occurs mostly after cycle. An hypothesis can be that stopping the cycle will dramatically drop the sebum production making the P. acnes bacteria to attack other tissues, or to go deeper into the pore.
If cystic acne is present better to go to dermatologist and ask for accutane, it should be taken under medical supervision. Low dose isotretinoine works good for acne, needs minimum 6 months treatment. Accutane has serious side effects, it is harsher than taking oral steroids , but it is the only solution for some type of acne, not to be taken lightly.
