Effect of Topical Platelet Extract Daily Serum as a Cosmetic Product to Reduce Facial Redness

Objective: The primary objective of this pilot study was to demonstrate the benefits of topical human platelet extract (plated)™ serum for the improvement of persistent facial redness.

Methods: This single-center, open-label pilot study evaluated six subjects using (plated)™ serum containing human platelet extract (HPE) with Renewosome™ technology twice daily for six weeks. The primary efficacy endpoint was a reduction in the Clinical Erythema Assessment (CEA) grade, and a reduction in Patient Subjective Assessment grade at six weeks. Secondary endpoints included an improvement in quality of life related to facial redness, and a reduction in redness by Mexameter™ spectrometry measurement. Safety data included monitoring for adverse events.

Results: Topical HPE serum demonstrated a statistically significant improvement in facial redness at Week 9 when averaging the Mexameter™ spectrometry results across nine regions of the face (p=0.0052). The primary and secondary endpoints were achieved. CEA grade at Week 6 demonstrated that all subjects improved by at least one grade, while one subject improved by two grades. One patient reported dryness. No other adverse effects were observed.

Limitations: Study limitations included a small sample size and lack of darker skin types (Fitzpatrick IV-VI).

Conclusion: This study demonstrates that topical HPE with Renewosome™ technology provides statistically significant reduction in facial redness and is safe and well-tolerated.
