Acne around Mouth

I've noticed recently that I have acne appearing on the rim of my lips - not actually on my lips, but on the edge of them.

They don't bother me most of the time, like any other type of acne, but I'm a trumpet player, so when my lips buzz, it rubs against the bump and causes mild irritation.

I noticed that they showed up when I started using chapstick more often - I use Burt's beeswax...

Is there any reason why this happening, and if so, can I prevent it?

I was really freaked out, as I am with any bumps, period, because I only have mild acne.

However, having them close to my lips bothered me.

Thank you.
