Possible Effect of Fraxel Laser on Acne Cyst?

I am a 40 yr old woman who is scheduled for my first Fraxel Restore treatment on Feb 11, for acne scars. Accutane kept my skin cyst-free for about 20 years, until I developed a large cyst 2 months ago. It was injected by a Derm PA in mid December. It improved somewhat, but I am left with a firm and non-fluctuant .5cm raised nodule.

What are the possible effects of Fraxel on this acne cyst? I'm thinking of two possible scenarios: a. break up the wall of the cyst, which can either speed resolution or empty contents and cause more scarring; b. increase cyst size by increasing sebum production. Thanks for any opinion on this.
