Isotretinoin is taken orally and is a strong drug that can have side effects that need to be considered in consultation with your doctor. In addition isotretinoin causes serious birth defects. Women need to start taking precautions a month before starting the drug and continue those precautions a month after stopping the drug. If you aren't a teenager but you still get acne, you aren't alone. AAD says there are some differences though.
Teens tend to get acne in what is called the t-zone, the forehead, nose and chin.
Adults tend to get acne along the jaw, lower cheeks, chin and neck. Women also seem to be impacted more in adulthood by hormonal fluctuations caused by menstruation and pregnancy. Although there are many things that can trigger acne, there's one thing experts say does not. Both the AAFP and AAD say the role of greasy food and chocolate in acne is greatly exaggerated. In fact research has shown that they have little if any impact on acne.
