Skin Care Review: Differin

I have had on and off moderate acne since forever and my pediatrian prescribed me benzamycin, which worked well and then it didnt so i went to a dermatologist and she prescribed me differin gel. However, this gel had absolutely no effect on my skin, it did not clear up my skin at all. I do not recommend differin gel...the information sheet tells the user that it will take about 2 months to become effective and for the first couple weeks that acne will appear to worsen, however, my acne did not worsen, furthermore, nor did it improve. Differin gel seems to be no different from ordinary over-the-counter medication, maybe even less effective...
