The addition of PRP to facial lipofilling: a double-blind placebo-controlled randomized trial.

Background: Lipofilling is a treatment modality to restore tissue volume, but may also rejuvenate the aging skin. Platelet-rich plasma has been reported to augment the efficacy of lipofilling, both on graft take and rejuvenation by altering the ADSC. Authors hypothesized that PRP addition would increase the rejuvenating effect while shortening recovery time. Methods: The study conducted was a single-centre, double blinded, placebo-controlled randomized trial (2012-2015). In total, a well-defined cohort of 32 healthy females enrolled in the study, with 25 completing the follow-up. All patients underwent aesthetic facial lipofilling with either saline or PRP added. Outcome was determined by changes in skin elasticity, volumetric changes of the nasolabial fold, recovery time and patient satisfaction during follow-up (1 year). Results: PRP did not improve the outcome of facial lipofilling when looking at skin elasticity improvement, graft volume maintenance in the nasolabial fold or patient satisfaction. Patient recovery after surgery however, dropped significantly. Furthermore, no skin rejuvenation effects from lipofilling could be observed. Conclusion: This study clearly demonstrates that the addition of PRP to the lipograft significantly reduces patient's reported recovery time, but does not significantly improve skin elasticity, volume retention nor overall patient satisfaction as compared to lipofilling alone. Moreover, reported effects of 'normal' (not SVF/ADSC enriched) lipofilling on skin rejuvenation, as has been reported and suggested to be seen in clinical studies when used in combination with facelift surgery, could also not be addressed.
