"i&#039;ve been prescribed to take this medicine twice a day for 15 days and have really bad cystic acne. i&#039;m about a week in and i think i&#039;m in the purging period. all of the deep cysts in my face are becoming nodules!! i hope this goes away fast. i suggest not using many other products with this as it makes your skin super sensitive and i&#039;ve been having a really red face if i use anything too harsh."
