Look bro I have tried most all solutions and here are the ones that I think work.
So you want it gone fast and you want a solution that is strong and also cheap?
Try DOXYCYCLINE (dox i SYE kleen) - Antibiotic from the doc depending on what country you live in. Works fast if you really just don't want to mess around and you want to kill the acne at the source.
Once you have tried everything and the acne is still bad and you want to drop the hammer on it for good..
Try ACCUTANE - Will need a dermatologist and it takes 5 to 6 months with blood work every month. Plus it is very expensive so hope you have medical else you will be spending thousands every month. It is hell to go through this but after you don't get any acne and life is great.
Really the only thing you can do other than that is try to dry your skin out and keep it clean via some ot the products mentioned above (most of which use alcohol to dry out the oilly skin).
RetinA can help if you just want to use a cream, but it is not as fast and you will not be able to be in the sun. In fact, none of the afforementioned solutions allow you to go in the sun. The easiest for sun exposure would be the DOXY. Also the shortest recovery time (4 to 8 weeks).
peace,
