Plasma Pen gone wrong...please help. How can I treat these white dots all over my neck? (Photo)

I had a Plasma Pen procedure in May 2020 and was not properly pre-treated. When I noticed that my pigmentation had lightened where the plasma pen procedure was done, the nurse did 3 additional procedures on my neck in one sitting. She did a Traditional Micro-Needling, Micro-Needling with RF, and an IPL. After these procedures were done, the white spots became hypertrophic. Now I have white dots all over my neck. PLEASE HELP! I am completely devastated by this!
