Big red pimple on my nose!

Hi,
I'm having a problem with pimples. I'm 13 years old, and this is NOT caused by puberty... It seems that I have bacteria trapped under the skin on my nose, and every... 3-4 months a BIG Huge pimple appears on my nose... at first I thought that it could be acne cysts, but I figured out that it was not... I seriously do not know what to do... I applied Benzyl Peroxide 5% on it.. I used to apply 10% and that would usually do the job, but I can't find it anymore.  

I usually popped the pimples when they were ready to be popped, and that would cause scarring.. since when I was 11 years old I had these kinds of pimples, and there's nothing I can do to get rid of them...

I still have scars on my nose, and my nose is still red and remains red from all the scars.. that's what is leading me to believe that there is bacteria under my skin...

Is there anyway that I could get rid of this bacteria?

Acne is caused by hormones, oil and bacteria. It may be that you can only get 10% benzyl peroxide on prescription, but there are a lot more effective products. Ask your doctor for a topical lotion like differin and a course of oral anti-biotics such as oxytretracycline. If you are female you could go on the pill when you're a bit older as this can help (sorry if you're not!) do not squeeze spots as this can spread the bacteria. This redness and scarring sounds superficial and will fade as your skin is young. Loiloi x
