Suggest Medication To Swelling Due To Impetigo Outbreaks

I ve had probably 2-3 impetigo outbreaks a year since I was 6. I ve gotten it in my eye, nose, eyelid, chin, and cheeks, but it almost always occurs somewhere on my chin. I have medication but it doesn t really help much anymore, even when it s relatively new. I ve resorted to diluted bleach baths which usually help a lot and get rid of it within 2 days. I have it again, and it doesn t itch anymore but it s really red and looks bad. It s about a 3cm diameter on my chin and is making my chin swell slightly (which has never happened except when I got it on my lower eyelid). Is this due to the bleach treatment? What should I do to make the skin heal?
