"i recommend this for people who have tried bc/otc treatments to no avail. i&#039;ve had acne all my life and everytime it gets super cystic, painful and covers my entire face i get back on the low dose. this past treatment i started in january with incredibly cystic painful acne on my chin, jaw, cheeks, and forehead. i would describe it as borderline severe acne. by june all of my acne was gone (unfortunately because my acne was so severe i am left with scars on my cheeks and chin). the only downside is it gets worse before it gets better and it takes a pretty long time to work."
