Platelet-rich plasma (PRP) is an extract enriched with growth factors that facilitate skin regeneration and rejuvenation. Here, the functionalities of PRP derived from various animal sources have been investigated and compared, focusing on its potential therapeutic applications in skin regeneration. Total antioxidant capacity, wound closure, and melanin content in cultured keratinocytes were used to evaluate the efficacy of different animal PRP sources. The PRP derived from deer exhibited the highest performance and was selected for subsequent proteomic and metabolomic analyses. Our findings indicate that deer blood is an optimal source of animal-derived PRP, demonstrating significant properties in promoting wound healing, anti-inflammatory responses, and skin regeneration. This identified PRP from deer sources can be developed as a safe and effective product for skin rejuvenation and regeneration.
