Grid marks and stamp marks on face after CO2 laser, will they go away? (Photo)

The grid pattern and marks are definitely within the realm of those seen 2 days after laser resurfacing treatments.  Make sure to contact the office of your board-certified dermatologist or plastic surgeon who performed the treatment, to review what you should expect over the coming days and weeks.  Best wishes. 

Two days? These are expected, your specialist who performed this procedure would have shown you the expected recovery times and healing process. This is very early scar remodelling. Impossible to give you an accurate healing time as it depends on the energy levels, density and passes- all this would have been covered prior to your consult. As a general rule 1-4 months, depending on skin type as well. All the best, Dr Davin S. Lim. Brisbane. Australia.
