Hmm maybe the acute effect was slight, then, because I never really noticed that. Or my pimples were too big. It did help reduce acne long term; but my skin began to hurt from it after regular application. And it is just so much effort to rub it onto my entire back, I just couldn't stick to the prescription. So I quit.
And I still use the Ibuprofen which you will scold me for...it works super well. About 100 or 200 mg on an average day (I only take it after I have slept less than 7 hours, and then I normally take 200 mg).
