What treatments should I get for my ice pick and boxcar scarring? I do not mind traveling (Photo)

I have ice pick and boxcar scarring. I have had several Microneedling and Chemical Peel sessions for them and nothing has worked. I am beginning to lose hope. Many dermatologists and estheticians in Texas do not know much about scarring and only offer micro needling, chemical peels and skincare products that do not help. I need to find an expert dermatologist who can help me.
