Had Morpheus8 for facial tightening, but now left atrophic grid marks on my face.

Had perfect skin only looking for a little tightening. I had one session of Morpheus8 4 months ago. Now 3 atrophic lesions developed over my cheeks. They have the same shape of the machine handpiece, volume loss and fat atrophy is evident. What is earliest time for fat transfer? Skin texture looks slightly bumpy overall. Went to a highly regarded PS in NYC, but obviously he didn't know the proper settings (depths, energy levels) or technique to operate the Morpheus8 safely.
