PRP vs. PRF: What’s the Difference and Why Rejuvenescence Uses Only Natural Fillers

By Dr. Karin Davis, DMD, MPAS, PA-C | Rejuvenescence Med Spa, Duluth, GA

When patients come to Rejuvenescence for facial rejuvenation, one of the first things they notice is that we do not offer hyaluronic acid fillers. No Juvederm. No Restylane. No Sculptra. This is not an oversight. It is a deliberate clinical philosophy: we believe the best material to restore your face is your own biology.

Instead, we use PRP (platelet-rich plasma) and PRF (platelet-rich fibrin), two regenerative injectables derived from a small sample of your own blood. Both harness your body's natural growth factors to stimulate tissue repair and collagen production. But they are not the same, and choosing between them matters clinically. Here is the complete explanation.

What Is PRP?

Platelet-rich plasma is produced by drawing a small blood sample, spinning it in a centrifuge at high speed to separate the components by density, and extracting the plasma layer concentrated with platelets. This platelet-rich fraction is then injected into the treatment area.

Platelets are best known for clotting, but they also contain a rich payload of growth factors including PDGF, VEGF, TGF-beta, and EGF, signaling proteins that orchestrate tissue repair and regeneration. When injected into aging or damaged tissue, these growth factors stimulate fibroblast activity, collagen synthesis, and new blood vessel formation.

PRP is liquid in consistency, making it injectable through fine needles into a wide range of treatment areas. It has a relatively short tissue retention time because it is rapidly metabolized, but its growth factor payload is released quickly and potently.

What Is PRF?

Platelet-rich fibrin is a second-generation refinement of PRP that uses a different centrifugation protocol, slower spin speed and no anticoagulant additives, to produce a more complex biological matrix. The result is a gel-like material that contains not only platelets and growth factors but also a three-dimensional fibrin scaffold threaded with white blood cells and stem cells.

This fibrin matrix is what distinguishes PRF from PRP clinically:

• Slower, sustained growth factor release: the fibrin scaffold acts as a natural reservoir, releasing growth factors gradually over 7 to 14 days rather than all at once. This more closely mimics the body's natural healing timeline and produces a more sustained regenerative response
• Gel-like consistency: PRF can be used as a soft tissue filler that provides mild immediate volume while simultaneously stimulating collagen over weeks and months. In its gel form, it can be injected into the under-eye area, nasolabial folds, lips, and other areas that benefit from both immediate lift and long-term regeneration
• Stem cell and white blood cell content: the inclusion of these additional cellular components enhances the regenerative and anti-inflammatory response beyond what PRP alone provides

PRP vs PRF: Side-by-Side Comparison

	PRP	PRF
Centrifugation speed	High speed	Lower speed (no anticoagulants)
Consistency	Liquid	Gel (can be used as filler)
Growth factor release	Rapid, concentrated burst	Slow, sustained (7-14 days)
Fibrin scaffold	No	Yes
Stem cells included	Minimal	Yes
White blood cells	Minimal	Yes
Immediate volume	Minimal	Mild (gel form)
Duration of effect	Shorter	Longer (collagen builds for months)
Best applications	Scalp, microneedling, joint injection	Face, under-eye, lips, skin rejuvenation
Available at Rejuvenescence	Yes	Yes

Why Rejuvenescence Uses Only PRP and PRF

Most aesthetic practices use hyaluronic acid (HA) fillers like Juvederm and Restylane as their primary volume restoration tools. These are safe, effective, and reversible, and there is nothing inherently wrong with them. So why do we choose not to offer them?

Our philosophy is grounded in Dr. Davis's dual training in oral and maxillofacial surgery and aesthetic medicine. From a surgical perspective, the most durable and natural-looking outcomes come from supporting and regenerating the body's own structures rather than adding foreign material to them. HA fillers add volume externally. PRP and PRF stimulate your own tissue to produce and rebuild.

Practical reasons we prefer natural fillers:

• No foreign material: PRP and PRF are derived entirely from your own blood, eliminating the risk of foreign body reactions, delayed hypersensitivity, or biofilm formation that can occur with any synthetic filler
• Genuine regeneration rather than masking: HA fillers fill space. PRF stimulates collagen and elastin production, improving the quality of the skin itself over time rather than simply adding volume beneath it
• Progressive natural improvement: results build gradually over weeks and months as new collagen matures. The result looks natural because it is natural
• No reversal needed: because there is no synthetic material injected, there is no risk of the complications associated with HA migration or the need for enzymatic reversal

Patients who choose Rejuvenescence understand that they are choosing a different philosophy: slower, gradual, natural improvement built on their own biology rather than immediate volume from synthetic material. This is not better or worse than HA fillers universally. It is better for patients who share this philosophy.

What Can PRP and PRF Treat?

PRF as a Natural Filler

• Under-eye rejuvenation: PRF gel addresses the hollowing and dark circles of the tear trough without the risk of Tyndall effect (bluish discoloration) that can occur with HA fillers in this delicate area
• Nasolabial folds and marionette lines: gradual collagen stimulation in fold areas improves skin quality and mild to moderate depth
• Lip enhancement: subtle, natural-looking lip volume and improved perioral skin quality
• Cheek and mid-face: mild volume restoration with significant skin quality improvement over 3 to 6 months

PRP Combined with Other Treatments

PRP is also used at Rejuvenescence in combination with Morpheus8 RF microneedling, applied topically or injected immediately following the microneedling session to amplify collagen stimulation and accelerate skin healing. This combination is one of our most popular regenerative protocols.

Who Is the Right Candidate for Natural Fillers?

• Patients who prefer regenerative, biologic treatments over synthetic materials
• Patients with mild to moderate facial volume loss, hollowing, or skin laxity
• Patients who have had reactions or concerns with HA fillers previously
• Patients who want progressive, natural-looking improvement over 3 to 6 months rather than immediate dramatic results
• Patients combining regenerative injectables with Morpheus8, Emface, or AccuTite for a comprehensive non-surgical facial rejuvenation approach
