Planning on getting a facial peel....who should i consult....aesthetician or dermatologist??

Getting facial peel...who would be most suitable to get the most desired result, and more importantly who will cost less and how much will the difference be..a lot...or not much??|||I have had a few done and they were all performed by a cosmetic physician at my dermatologists. I was very pleased with the results. I paid $100 per peel. Hope this helps.
