Can CO2 laser induce growth of keloids?

Hello, I had a CO2 laser procedure 3 weeks ago on face keloid (on the chin). The treated keloid got very red and swollen, seems like its size increased. I have used fusidic acid since day 2 for 20 days and mometazone since day 3 for 15 days. Also, doctor injected botox in the keloid right before the CO2 treatment. Could all these result in a bigger keloid?
