Can i use PRP system treatment as a full body skin lightening procedure?

We would not recommend this PRP it is not guaranteed to lighten the skin.  If you're looking to treat the full body in one treatment it would require too much blood to be drawn for the treatment.

PRP is not used to my knowledge as a full body lightening treatment, but your question is not very detailed to begin with. You may want to consider skin brightening topical creams if you are seeking lightening treatments. Best, Dr. Anil Shah

This can’t possibly be done. It would drain your blood. I’ve not used Prp for skin lightening either. There are other systemic options like glutathione but topicals make more sense.
