Thank you for your question. The experience of the operator is an important factor in the efficacy of the procedure. Always consult with a board certified facial plastic surgeon.
Thank you for your question and photos. Typically the direction of the laser will not make a difference once you have recovered from the laser. Once you have exfoliated and your skin has re-epithelialized, the texture and overall appearance of your skin will appear even and smooth. Good luck.

Tracking can occur when a laser is treated in only one direction. Making sure there is careful overlap minimizes these track marks. In most procedures with laser we usually 'mow the lawn', ie treat in overlapping passes in order to give even, smooth and consistent results.
The direction of the pattern doesn't matter as long as the total surface was evenly treated. You won't even notice those lines when you finish recovering.
The direction of fractional CO2 laser resurfacing does not typically matter if the provider is experienced. However, I typically go in both directions to provide an overall more even, consistant result.

I hope this helps.
Overall, it should not make a difference in the long run but initially you may see this pattern for a few days to weeks depending on the laser that was used. If they did more than one pass, this might just be the last direction the doctor went in.
It should even out as you heal, but may see the pattern for a while. Usually we try to go in both directions so there is not visible pattern. If they did more than one pass you may just be seeing the last direction they went in.
