Can you have eMatrix over a probably cystic pimple?

I have ematrix tomorrow and have a small cystic pimple that wont go away and has been there for close to 2 weeks..i have a small acne scar under the pimple and wanted it "zapped" by the ematrix and I'm wondering if I can have the pimple area treated with the ematrix and if it will help it go down and prevent/lessen scarring or if ematrix should never be done on a cystic like pimple? can doing ematrix on a pimple CAUSE scars?
