Acne may have started in your teen years, that time when age and hormones meet to cause those awful breakouts. It is a common problem that many teenagers face. However, many adults suffer from acne as well. Women typically develop acne during their menstrual cycle. Cause is hormones surge before or during menstrual cycles causing excess oil to clog pores. Acne may appear as deeper lumps (cysts or nodules) on the face, neck, chest, back and sometimes shoulders.
