At the Forefront of What's Next
Dr. Macrene Alexiades doesn't just formulate skincare. She conducts the research that shapes the future of aesthetic medicine.
Her latest work centers on platelet-rich fibrin (PRF)—and the findings are redefining how we think about skin regeneration.
"My research centers on platelet-rich fibrin (PRF), and I have developed the largest case series in aesthetic medicine to date. This work positions PRF as a meaningful advance over the better-known platelet-rich plasma (PRP), and the distinctions are both biological and clinical.
PRP, while widely adopted, is an anti-coagulated plasma concentrate. It delivers a bolus of growth factors, but those factors are released rapidly and the preparation requires additives such as anticoagulants or activating agents. PRF, by contrast, is produced without additives—it is spun at a lower centrifugation speed, preserving a natural fibrin matrix that acts as a slow-release scaffold for growth factors, cytokines, and leukocytes. The result is a more sustained, structured, physiologic delivery of regenerative signals to the treated tissue. Put simply, it is your own body's filler with sustained release of growth factors and stem cell factors over a long duration.
Clinically, this translates to several advantages. In my case series and in my artistic hands, PRF demonstrates immediate improvements in wrinkles, laxity and skin quality. It is showing proof of superior tissue regeneration, enhanced collagen stimulation, and a favorable safety profile—precisely because it is an entirely autologous, additive-free preparation. Patients also benefit from a more natural integration, with far less risk of inflammatory reaction or delayed puffiness as seen with manufactured fillers.
My data thus far are clear: PRF represents the next generation of autologous biologics in aesthetic medicine, not merely an incremental refinement of PRP, but a fundamentally different and more sophisticated biological tool."

Why This Matters for Your Skin
Dr. Macrene's research reveals a fundamental truth that guides everything she does—clinically and in her formulations: the most sophisticated regenerative signals are already inside you.
PRF works because it harnesses your body's own growth factors, cytokines, and stem cell signals—delivered slowly, naturally, and without synthetic additives. No foreign materials. No inflammatory reactions. Just your biology, optimized.
This is the same philosophy behind MACRENE Actives.
From the Clinic to Your Routine
Dr. Macrene's clinical research doesn't stay in the procedure room—it directly informs every formula she creates. The same principles that make PRF revolutionary in aesthetic medicine guide her skincare approach:
Sustained release over rapid delivery
PRF's slow-release fibrin scaffold mirrors how MACRENE formulations deliver actives—concentrated botanicals and peptides absorbed gradually, working continuously rather than spiking and depleting.
Additive-free, clean formulations
PRF's power comes from its purity—no anticoagulants, no activating agents. MACRENE Actives are formulated with the same philosophy: no toxic preservatives, no synthetic additives, nothing that doesn't serve your skin's biology.
Growth factor and collagen stimulation
PRF's clinical advantages center on collagen stimulation and tissue regeneration. High Performance Face Serum's peptide complex works through identical pathways topically—signaling the same collagen synthesis and structural regeneration that Dr. Macrene witnesses clinically every day.
Natural integration without inflammatory reaction
PRF's autologous nature means minimal inflammatory response. MACRENE's clean botanical formulations are designed with the same tolerance principle—clinical potency without triggering the inflammation that undermines results.
