"i was diagnosed with pcos (ploy cystic ovary syndrome) and my spots were horrible, on my face, back, shoulders. since in been using duac - once every two days as told by my gp, my confidence is returning, i don&#039;t feel the need to wear make up all the time, all i now have are some acne scars on my chin and back, which will clear up in time. i give my body a week to two weeks off at the 12 week cycle and re start as my hormones release the spots again. don&#039;t know what i&#039;d do without duac!!!"
