Just use an antibacterial wipe 3 times a day, as soon as you wake up, in the middle of the day and before bed, this SHOULD work, but, if it doesnt you should think about taking an antibiotic to get rid of it, dont just take any though because most affect protein synthesis which i assume you wont want so use one called augmentin if the improved hygiene way doesnt work.
Im not being rude either when i say improved hygiene because it happens to a lot of people, its just that if your suffering from acne then you need to step up removing bacteria from the affected areas, i once got a few boils on my back when i was using sus and using the antibacterial wipes as well as my usual 2 showers a day got rid of them in about 2 weeks.
