Review demonstrates enhanced efficacy when adding platelet-rich plasma to microneedling for atrophic acne scarring, suggesting synergistic benefits in collagen remodeling.
Key Points
To critically review clinical trials evaluating the therapeutic efficacy of microneedling monotherapy compared with combination microneedling and platelet-rich plasma for atrophic acne scars.
Reviewed recent clinical trials assessing outcomes of microneedling monotherapy versus microneedling paired with autologous platelet-rich plasma (PRP).
Analyzed biological mechanisms involving controlled microinjury, collagen synthesis induction, and the delivery of concentrated autologous growth factors and cytokines.
The combination of microneedling with PRP delivers supraphysiologic levels of platelets and cytokines directly to microtrauma sites, promoting accelerated tissue remodeling.
Clinical evaluations consistently show synergistic enhancements in scar revision and skin recovery when combining PRP with microneedling compared to microneedling alone.
