HI there. It is difficult to accurately answer your question without seeing a picture or knowing why you are desiring those procedures. Morpheus 8 is an excellent radiofrequency microneedling procedure that allows for controlled depth penetration of radiofrequency energy to decrease fat, induce collagen formation, and cause muscle contraction. It works on scars, reduced wrinkles, tightens skin and rejuvenates. PRP involves using your own spun down plasma which is ripe with growth factors, fibroblasts etc and injecting it back into a desired area also to rejuvenate, fill in wrinkles, treat scars etc. They both have similar purposes. I suppose the decision to add on prp would depend on what you are treating, how deep the lines or scars are etc. It is possible that the prp would add somewhat of a more instantaneous affect with the filing affect. They are great adjuncts together, but not always necessary to do together. With both procedures, some of the affects will develop over time over a month, two months, three months, etc.
