Age 57 & had 2 PRF treatments all over my face, neck & hands

I have had two PRF treatments. I decided not to do the PRF microneedling because I am a performer and didn't want a lot of down time. I received small injections of my own plasma all over my face, neck and she even did my hands. I'm told 4 or more treatments are best and if done with a biostimulator you can really see great results. I'm also told it can take months before you start to see results like thicker skin. I'm especially concerned about the skin around my mouth below the lower Lip. I'm losing volume there as well as in the temple and check area. I am trying to avoid fillers. Ive had a face and neck lift about 7 years ago. I'm 57 years old. I'm in the entertainment business where YOUTH is a large component. Has anyone had PRF treatments without microneedling and I'm wondering what is better? With microneedling or with biostimulators or both?
