Why am I breaking out after microdermabrasion?

I had microderm done a week ago. I was on retin a and had used it the night before. I mentioned this to the esthetician and she said my skin could tolerate it. She went over active acne and said she extracted them and it did seem like it at first but a couple days later my acne got worse. The pimples she said she extracted got a lot bigger and others starter popping up! Still breaking out a week after, is this normal?
