Thanks for sharing your question. I can appreciate your concern.
Maintenance is a must for the long lasting results of your CO2 laser. You can start the maintenance as soon as 3 months (enough time to heal the wounds. ) However, you may start considering it only until the skin is healed and ready to tolerate more trauma. 3-6 months after.
Finally, make sure that you have a consultation with a board certified plastic surgeon.
Wishing you the best in your journey
