Outlined Squares After Micro Laser Peel

This can occur. Usually the geometric pattern of the laser is overlapped such that there aren't any intervening bridges or entirely untreated skin. It is possible that the treatment areas were not overlapped where you see boxes. This will likely settle over time and not require additional treatment. However, it is possible to go back and treat those areas if they persist after healing to provide a more uniform appearance. Stephen Weber MD, FACS

The outlined squares should be confluent over most of the face after a full face 50 micron laser peel but you may have some areas with defined squares not touching the others.  This is due to the way the scanner on the laser lays down the pattern and it is up to the operator to make the patterns slightly overlap one another to obtain a uniform treatment.

I would return to your provider to assess the areas which you believe may be hyper pigmentation so that the may be evaluated and addressed appropriately.

Yes it is normal to have a geometric pattern of dots after any fractionated treatment.  The ablative energies utilized, pulse duration and density (how far the dots are separated) are the important parameters for long-term results, but the dot pattern in the skin can vary.  Some areas of your skin will peel more slowly and show the dot pattern for a longer time, which initially makes the treatment look irregular, but the long-term results are more based on the density used across the whole face.

If you think an area was missed and you have an area of intact skin that did not peel, you should contact your laser surgeon for examination of this area.
