Recommendation for doctors who do nanofat injections (grafting) in New York metro area?

Have dermal skin atrophy under eye (periorbital) and interested in nanofat for stem cell healing benefits to help regenerate dermal structure, but not looking to add any substantial bulk. I've read true nanofat is processed to break down all the larger fat cells to just leave a thin emulsion rich in stem cells. From reading, it seems some add PRP to enhance and use micro cannulas to inject so as to reduce bruising? Does this enhance effectiveness?
