PRP and effectiveness for hollowness and skin redness?

There is a lot of pseudoscience and marketing that surrounds PRP, in part due to a lack of standardization of this modality. 
The reality is that it does 'not' do very much when injected for aesthetic reasons to the face. After a few minutes, it gets washed out by the blood flow. It is most certainly not a meaningful solution for hollowness! 
There are better 'variants' of PRP, mind you. Also, it should be used in conjunction with other modalities and products. When used in isolation, however, all it does is to give very temporary volumization with no other tangible change.

Hi NoVaFace,It's hard to tell what can be done without photos. But yes, microneedling with PRP could work. However, we don't suggest injecting the PRP but just spreading it on before and after microneedling. Ask your doctor whether you are a good candidate for dissolving vascular lesions and discoloration with lasers.All the best, Justin Harper, M.D.
