Even the rain breaks me out. What's the dillio? I'll be just walking, minding my own buisness, then all of a sudden a drop will drop on my cheek. An hour later, and a lovely cyst has formed. Or if it's windy outside and my hair will be flowing in my face I break out. Oh mother nature..
Does anyone else have this problem? 
And if so, or if not, how come this happens?
I urge you to get cortisone shots whenever you get cysts or nodules. The pimple will go away fast, but there still will be a red mark for a while. This will prevent any real scarring. I think I have one real scar from before I knew about cortisone shots.
Also, try oral antibiotics. They are a really good preventative measure and a million times better than just benzoyl peroxide. They can be bad in the long run, but killing your stomach flora temporarily is nothing compared to the pain that comes from acne.
