PRP vs PRF: What Is the Real Difference?

Both treatments start with your own blood. Both concentrate platelets. Both get injected for similar purposes.

The differences come down to how the blood is processed and what that changes about the final product. This guide explains what actually separates them and which tends to suit which purpose.

The Short Version

The comparison of PRP vs PRF comes down to two processing choices: whether an anticoagulant is added, and how fast the blood is spun.

PRP uses an anticoagulant and a faster spin. The result is a liquid concentrate of platelets.

PRF uses no anticoagulant and a slower spin. The blood begins to clot naturally, forming a fibrin mesh that traps platelets and white blood cells.

That fibrin mesh is the meaningful difference. It releases growth factors more gradually rather than all at once.

How PRP Is Made

The process takes place during your appointment.

Blood is drawn, typically 15 to 60 milliliters depending on the treatment area
An anticoagulant is added to prevent clotting
The sample spins at relatively high speed in a centrifuge
Components separate into layers by density
The platelet-rich layer is drawn off
That concentrate is injected or applied

The result: A liquid rich in platelets, which carry growth factors involved in tissue repair.

How PRF Is Made

The process looks similar but differs in two specific ways.

Blood is drawn
No anticoagulant is added
The sample spins at lower speed for a shorter time
Natural clotting begins, forming a fibrin matrix
That matrix, containing platelets and white blood cells, is collected
It is injected, or used as a gel-like membrane

The result: A scaffold rather than a liquid. Because clotting starts immediately, PRF must be used within minutes of preparation.

The Three Real Differences

Everything else follows from these.

1. Additives

PRP contains an anticoagulant. PRF contains nothing but your own blood. For patients who prefer no added substances, that matters.

2. Release rate

PRP delivers growth factors relatively quickly. The fibrin matrix in PRF releases them more gradually over a period of days, which is the main clinical argument for it.

3. White blood cell content

PRF generally retains more white blood cells. These take part in healing and immune signaling. Whether more is better depends on the application and is still debated.

Side-by-Side Comparison

Factor	PRP	PRF
Anticoagulant	Yes	No
Spin speed	Higher	Lower
Final form	Liquid	Fibrin matrix or gel
Growth factor release	Faster	More gradual
White blood cell content	Lower	Generally higher
Time before use	More flexible	Must be used quickly
Research volume	Larger	Smaller, newer
Typical cost	Varies	Often similar or slightly higher
Can be combined with fillers	In some protocols	Used as a natural volumizer

Which Suits Which Purpose

Providers generally choose based on the treatment area.

PRP is often preferred for:

Hair restoration, where it has the largest research base
Joint injections
Combination with microneedling
Situations requiring a more liquid product

PRF is often preferred for:

Under-eye treatment, where its gradual release and natural composition are advantages
Facial volume support
Areas where a slower, sustained effect is desired
Patients who prefer no additives

Either may be used for:

General facial rejuvenation
Combination protocols with microneedling
Scalp treatment

An honest note: Provider preference and training influence this choice as much as evidence does. Ask your provider why they recommend one for your specific situation.

What the Evidence Shows

PRP has the larger body of research, particularly for hair restoration and certain joint applications. Study quality varies because preparation protocols differ widely between clinics, which makes comparing results difficult.

PRF is newer. Research is growing, particularly in dental and oral surgery contexts where it has been used extensively. Aesthetic applications have less published data.

What neither has: Large, standardized trials directly comparing the two across cosmetic applications. Claims that one clearly outperforms the other are not well supported.

Practical takeaway: Both are reasonable options. Neither is dramatically superior across the board. Preparation quality and injector skill likely matter more than which one you choose.

What to Expect at Your Appointment

The visit follows the same general pattern for both.

Consultation and evaluation of the treatment area
Blood draw, similar to any routine lab draw
Numbing cream applied while the sample processes, roughly 20 to 30 minutes
Centrifuge processing
Injection or application, typically 15 to 30 minutes
Aftercare instructions

Afterward:

Mild swelling, redness, or bruising for a few days
Tenderness at treatment sites
Return to most normal activity the same day
Avoid strenuous exercise for about 24 hours
Avoid alcohol and blood-thinning supplements as directed

Results timeline: Both work gradually. Expect early changes around weeks 4 to 8 and fuller results at 3 to 6 months, depending on the application.

Safety and Candidacy

Because both use your own blood, allergic reaction risk is minimal.

Reasonable candidates:

Generally healthy adults
Realistic expectations about gradual improvement
No active infection at the treatment site
Normal platelet function

Not appropriate for people with:

Platelet disorders or significant clotting abnormalities
Active infection at or near the site
Active cancer
Certain blood disorders
Pregnancy or breastfeeding
Anticoagulant therapy, without physician clearance

Discuss with your physician if you: take blood thinners, have an autoimmune condition, or have had a poor response to a previous treatment.

Conclusion

The practical difference between these two is processing: PRF skips the anticoagulant and spins slower, producing a fibrin matrix that releases growth factors gradually. PRP is a liquid concentrate with faster release and a larger research base.

Both are reasonable, and neither is clearly superior overall. Ask your provider which they recommend for your specific area and why, and pay more attention to their experience than to which product they use.

FAQs

Is PRF better than PRP?
Neither is clearly better overall. PRF releases growth factors more gradually and contains no additives. PRP has more research behind it, particularly for hair.

Does the procedure hurt?
Numbing cream makes it tolerable. Most people describe pressure and brief stinging rather than significant pain.

How many sessions will I need?
It depends on the application. Facial and hair protocols commonly start with three sessions, followed by maintenance.

Can I be allergic to it?
Allergic reaction is essentially not a concern, since the material comes from your own blood.

How long do results last?
Typically several months to a year depending on the area and your individual response. Maintenance sessions are usually recommended.

Is PRF used for under-eye hollows?
Yes, it is a common application. Its gradual release and natural composition are the usual reasons given for choosing it there.

Can I combine either with microneedling?
Yes. Combining with microneedling is a common protocol for facial treatment.

Do I need to stop any medications first?
Your physician will advise. Blood thinners and certain supplements typically require discussion before treatment.
