Yes, it is safe to do ablative lasers like fractional co2 even while on Accutane/ Isotretinoin.
The latest research published in 2018 shows that it is safe to have Laser treatments - even Ablative laser treatments without a 6 month delay in Isotretinion.
Practically speaking, there is an increase in skin dryness after an ablative laser - especially for the first 1 week. Some patients experience this effect more than others.
This dry-ness might be further worsened by Isotretinoin/Accutane.
Hence, I usually restart my patients on Accutane 1 week after the laser treatment to avoid excessive dry skin.
My advise is to check with the doctor who performed laser treatment for the most appropriate time to restart Accutane.
Hope that this helps!
Warmest regards,
