DPL System by MUAC (Make Up Artists Choice) vs. Gentle Waves. Is Doxycycline Okay?

I am looking at Gentle Waves therapy to address 40+y/o female hormonal acne/cystic acne and fine lines. It's $50/session in the office. I was looking at the Quasar line but that would take a long time to do daily. The DPL System by MUAC is free standing and would take less than 20 minutes and would be worth the $350/ if it works. I'm on doxycycline, is that a problem? If so how long should I wait until I am off the doxy? I've been off Accutane 6 months (no results) can I try the LED txs now?
