"i&#039;m 15 years old and i&#039;ve been on this treatment for around about a year. straight away when i started using it my skin totally cleared up within weeks. i stopped using the treatment for around about 2-3 weeks and i immediately noticed within a week of not using it my spots had came back. i couldn&#039;t get hold of the duac because there was a manufacturing problem but when i could get it again and i started using it my spots wouldn&#039;t go away. it took around 2 month to get clear skin the first time around but the second it took around 8 months. another problem i&#039;ve had with duac is about 2-4 times i&#039;ve used the duac its burnt my face so i&#039;ve had to rub it off and it tends do give me really flakey,dry, tight skin. overall i think its really good"
