Do you think that this will work???

I have had acne since I was about 11 and ever since then I have tried pretty much everything to treat acne, and all the stuff you can get at the stores. It would work for a while then stop after a few months, but never once did they completely clear my face. I always made sure to take real good care of my face, but I would still break out. It was so frustrating, especially on self-conscious levels and the pain that acne causes. It was also very frustrating and time consuming to have to put on make up to cover the acne and scars and all the rituals to take care of my face. I went to a dermatologist who gave me Accutane, which still didn't do the trick completely.I was surfing on the net recently to know about some medication against acne and found this, I have quoted it to show you:http://www.drugdelivery.ca/s3194-s-DIFFERIN.aspx
Do you think that this gel is worth taking to treat acne???
