Abstract

BACKGROUND: Exosomes are regenerative mediators for skin rejuvenation. Human platelet extract (HPE) is an allogeneic exosome product derived from US-sourced, leukocyte-reduced apheresed platelets with consistent purity and potency. OBJECTIVES: The authors sought to better characterize the safety and tolerability of novel HPE (plated) Intensive Repair Serum (Rion Aesthetics, Rochester, MN) and its maximal effects on skin rejuvenation at 6 weeks. METHODS: This prospective, single-arm, non-randomized, longitudinal study investigated the safety and efficacy of HPE. Structured sub-analysis evaluated multifactorial improvement in skin health following standardized skin care regimen to determine the maximal effect. Evaluation at baseline and 6 weeks included participant questionnaires and photo documentation with VISIA-CR Generation 5 3D PRIMOS (Canfield Scientific Inc, Fairfield, NJ). RESULTS: VISIA-CR imaging yielded quantifiable and statistically significant improvements in overall skin health (skin health score). A greater score correlated to greater overall skin health, and there was a statistically significant mean delta improvement of 224.2 ± 112.8 (mean ± standard deviation, P ≤ 0.0001) in skin health score at 6 weeks compared with baseline. This correlated to reduction in redness, wrinkles, and melanin production across all cosmetic units (P = 0.005, P = 0.0023, P ≤ 0.0001, respectively) and significant improvements in luminosity and color evenness (P ≤ 0.001). CONCLUSIONS: A topically applied platelet-derived exosome product, HPE, induced normalization to skin health at 4 to 6 weeks with improved various clinical measures of facial photodamage and cutaneous aging. It is safe, well-tolerated, and well-liked by participants.
