Katie is SO detail oriented and meticulous. I just love working with her because of her attention to detail and how specific she is with her work. She looks at your actual anatomy and proceeds based on the right work for your face! I also love that she has so many holistic alternative non toxic options like PRF Gel and PRP with microneedling to name a few. She is a very skilled injector and you will feel like a piece of art that she is curating when she works on you. I refer all of my people to her! So happy to have found her.

PRF injections in Scottsdale
nothing but your own blood
A small draw, spun slowly, injected back. No synthetic product, no filler, no allergy risk. PRF treats under-eye hollowing, thinning hair and skin quality by delivering your own growth factors over seven to ten days rather than in a single burst.

Your own biology,
concentrated
Platelet-rich fibrin is made from a small sample of your own blood. We draw it much as any clinic draws routine bloodwork, spin it in a centrifuge for around ten minutes, and separate the layer rich in platelets, white blood cells and fibrin. That layer is injected back into the area being treated.
Platelets are the body's repair signal. Concentrated and placed where you want regeneration to happen, they recruit the cells that build collagen, improve microcirculation and — in the scalp — extend the growth phase of a hair follicle.
The distinction from PRP is the spin. PRP is centrifuged fast with an anticoagulant added, producing a liquid that releases its growth factors quickly, largely within a day. PRF is spun slowly in a plain tube with nothing added, which allows fibrin to form a natural mesh. That mesh holds the platelets in place and releases growth factors gradually over seven to ten days — and it retains stem cells that PRP's processing discards.
- ✓Entirely autologous — your own blood, with nothing added
- ✓Free of allergy risk, because there is no foreign material
- ✓Gradual, building over weeks rather than appearing immediately
- ✓A regenerative treatment rather than a volumising one
- ✕A filler — it does not lift or project the way hyaluronic acid does
- ✕Reversible; unlike hyaluronic acid, there is nothing to dissolve
- ✕A single-session treatment — a course is how it works
- ✕A cure for advanced hair loss where follicles are no longer viable
By the session,
with the course planned
PRF is priced per session, and it works as a course — usually two to three sessions for the face and three to four for hair, spaced four to six weeks apart. We assess at consultation, tell you how many you are likely to need, and quote the course so you can judge the real cost before you begin rather than after session two.
Course length depends on the area and the concern. PRF EZ Gel and microneedling with PRF are separate treatments, quoted separately.
Seven things PRF
is genuinely good at
PRF is regenerative rather than volumising. Below is where that distinction works in your favour — and where a filler or a different treatment would serve you better.
Under-eyes · tear trough
The most requested PRF treatment. It improves skin quality, thickness and circulation in the thinnest skin on the body, softening hollowing and dark circles gradually. Because it is your own blood there is no risk of the blue-grey tint that superficial filler can cause here.
Dark circles
Where discolouration comes from thin skin and visible vasculature rather than pigment, PRF thickens the dermis and improves the way light passes through it. Pigment-driven circles need a different approach.
Thinning hair
Injected into the scalp, PRF extends the growth phase of the follicle and improves the blood supply feeding it. It works where follicles are miniaturising, not where they are gone — early intervention matters enormously here.
Receding hairline
Along the frontal hairline and temples, where thinning usually shows first. Often combined with medical therapy for a better result than either alone.
Overall skin quality
Fine lines, dullness, laxity and texture across the face and neck. Frequently paired with microneedling, which delivers PRF through the channels the needles create.
Acne scarring
PRF alone does relatively little for scarring; combined with SkinPen microneedling it noticeably accelerates and improves the collagen response.
Volume loss
Standard PRF does not lift or project. If you want structural volume restored, PRF EZ Gel gives a softer autologous option and hyaluronic acid filler gives a firmer one.
From blood draw
to new collagen
The whole process happens in one appointment, and most of it takes place while your numbing cream works.
A small draw
Much like routine bloodwork and over in under a minute. The amount depends on the area being treated — under-eyes need considerably less than a full scalp.
Slow spin, plain tube
Around ten minutes in the centrifuge at low speed, with no anticoagulant added. This is the step that distinguishes PRF from PRP and it is why the fibrin is able to form at all.
A fibrin scaffold forms
Fibrin creates a natural mesh that physically traps platelets, white blood cells and stem cells. Without an anticoagulant fighting it, the body's own clotting architecture assembles in the tube.
Placement
Cannula under the eyes, where blunt technique markedly reduces vascular risk. Fine needle across the scalp in a grid. The plane matters as much here as with any injectable.
Sustained release, then regeneration
Growth factors release from the scaffold over seven to ten days, recruiting fibroblasts and improving microcirculation. New collagen builds over the following weeks, which is why results appear at four to eight rather than immediately.
An hour,
most of it numbing
Assessment
We establish whether your concern is genuinely suited to PRF. Under-eye hollowing from volume loss, thin skin or pigment are three different problems with three different answers, and only some of them are this one.
Blood draw
A small draw, over in under a minute. Arriving well hydrated makes it easier and improves the yield.
Spin while you numb
Ten minutes in the centrifuge at low speed, running while your topical anaesthetic works. The two happen in parallel so nothing is added to your appointment time.
Injection
Cannula under the eyes, fine needle in a grid across the scalp. Ten to twenty minutes depending on the area.
Aftercare and your next session
Written aftercare and an honest warning about swelling if we treated under the eyes. Your next session is booked four to six weeks out.
PRF injections
before and after

Individual results vary. All photographs are of KORA patients, unretouched, in identical lighting and framing, published with written consent. PRF results are shown at least eight weeks after the final session.
PRF timeline, week by week
PRF under the eyes causes firm swelling for two to four days, more pronounced initially than hyaluronic acid filler. Results build gradually from around four weeks and reach full effect at eight to twelve weeks. PRF typically lasts 12 to 18 months.
Treating before an event? Allow at least three weeks per session, and remember the result itself takes two to three months to arrive. PRF cannot be rushed.
The swelling is firm,
and it surprises people
Under-eye PRF swells more in the first few days than hyaluronic acid filler does, and the swelling is firm rather than soft — patients frequently describe it as feeling like a small pad under each eye. It peaks at 24 to 72 hours and settles by day four to seven. This is not a complication; it is the fibrin matrix in place before the tissue absorbs it. Knowing that in advance is the difference between a patient who waits calmly and one who panics on day two. Plan around it: treat on a Thursday, allow three weeks before anything photographed, and expect no visible result at all for the first month.
- ✓Firm swelling for 2–4 days is expected
- ✓No visible result for roughly 4 weeks
- ✓Treat at least 3 weeks before any event
The trade-off
against filler
Hyaluronic acid filler under the eyes can be dissolved within days if you dislike it. PRF cannot — there is no hyaluronidase equivalent, because it is your own tissue. That is a genuine consideration and it cuts both ways. PRF carries no risk of the blue-grey Tyndall tint that superficial filler can cause here, no risk of the water-attracting puffiness that tear trough filler sometimes develops, and no allergy risk whatsoever. But it is also not reversible, so we treat conservatively and build across sessions rather than trying to achieve everything at once.
- ✓No Tyndall effect and no allergy risk
- ✓But no reversal option either
- ✓Treated conservatively across a course
It works on follicles
that are thinning, not gone
PRF improves the blood supply to a follicle and extends its growth phase, which is genuinely useful where hair is miniaturising — becoming finer, shorter and lighter. It does nothing at all where the follicle has been lost entirely, because there is nothing left to stimulate. This makes timing the most important variable in the whole treatment: patients who come at the first sign of thinning do considerably better than those who wait years. We will assess honestly and tell you if we think you are past the point where PRF will help, and where a surgical referral or medical therapy is the better route.
- ✓Effective on miniaturising follicles
- ✓Ineffective where follicles are lost
- ✓Early treatment substantially outperforms late
Why the spin speed
changes everything
PRP and PRF are used almost interchangeably in marketing and they are not the same treatment. PRP is centrifuged at high speed with an anticoagulant added to keep it liquid, producing a solution that releases its growth factors quickly — the majority within the first twenty-four hours. PRF is spun slowly in a plain tube with nothing added at all. Without an anticoagulant, fibrin forms a natural mesh that traps platelets, white blood cells and stem cells, releasing growth factors gradually across seven to ten days. For skin regeneration and for hair, where the follicle cycle runs over weeks rather than hours, we consider sustained release the better mechanism — and the absence of any additive means what goes back in is purely your own blood.
PRF or PRP, and when is filler better?
For under-eyes the real decision is between PRF and hyaluronic acid filler, and it turns on one question: is your hollowing a volume problem or a skin-quality problem? Filler restores volume immediately and can be dissolved. PRF improves skin thickness and circulation gradually and cannot. PRP is the same idea as PRF processed differently and less well. EZ Gel sits between them.

What Scottsdale says about PRF at KORA
Today I had my first appointment with Katie. She was lovely and very thorough with information about the service I received. I had been researching different options to treat under the eye for some hollowness and to refresh the skin in that area. I discovered that Katie offers PRF for under the eyes. I wanted a treatment that wasn't so aggressive or harsh. For me this was the best option. After discussing what to expect She drew my blood and numbed the area under my eyes. Then it was time for my platelets to be injected. It wasn't terribly uncomfortable but I did feel it slightly. My entire appointment was less than an hour long. It's only been about 4 hours since the injections and the swelling is visible but manageable. I have been applying arnica and its helped. I am in it for the long haul and don't expect the full results until months down the road after I've had at least 3 treatments. I'm really glad to have found Katie and I look forward to my next appointment.
Ally did PRF on my hair. It was my second treatment and she made me feel so comfortable! Further, it did not hurt and Ally is adept at finding areas on the scalp that are thinning! Glad I found Kora Aesthetics. Location is convenient and everyone at Kora truly cares about their clients!
How to prep & what the first week looks like
Hydration matters more than you would think
- Drink plenty of water the day before and the morning of. It makes the draw easier and genuinely improves the PRF yield.
- Eat a proper meal beforehand. Injections on an empty stomach after a blood draw are the most common cause of feeling faint.
- Avoid alcohol for 24 hours and caffeine on the morning of treatment.
- Tell us about any blood thinners, platelet disorders, anaemia or recent illness — these affect both the draw and the result.
- If treating under the eyes, allow at least three weeks before any event. Firm swelling lasts two to four days.
- Reschedule if you have an active infection or are unwell.
- Let us know if you are pregnant, trying to conceive or breastfeeding — we will not treat you.
The first week
- Under-eyes: expect firm swelling for two to four days. It is more pronounced than filler swelling and it is expected, not a complication.
- Ice gently for the first 24 hours and sleep with your head elevated for two nights.
- Do not rub or massage the treated area.
- Scalp: do not wash your hair for 12 hours, and avoid harsh products or heat styling for 48 hours.
- No strenuous exercise, sauna, steam or hot tub for 48 hours.
- Avoid alcohol for 24 hours and anti-inflammatories where your physician agrees — they can blunt the healing response PRF depends on.
- Expect no visible result for about four weeks. This is normal and is not a sign it has not worked.
- Call us for spreading redness, heat, pus, fever, or swelling that worsens rather than improves after day three.
PRF questions, answered properly
Basics
What is PRF?+
Platelet-rich fibrin, made from a small sample of your own blood. It is spun slowly in a plain tube with no anticoagulant, which allows fibrin to form a mesh that traps platelets, white blood cells and stem cells and releases growth factors gradually over seven to ten days.
How many PRF sessions will I need?+
Two to three for under-eyes and facial skin quality, three to four for hair, spaced four to six weeks apart. Maintenance is usually annual for the face and every four to six months for hair.
When will I see results from PRF?+
First changes appear around four weeks, with the full result at eight to twelve weeks after your final session. PRF is regenerative rather than volumising, so nothing is visible on the day.
PRF vs PRP
What is the difference between PRF and PRP for the face?+
PRP is spun fast with an anticoagulant added, producing a liquid that releases growth factors largely within the first day. PRF is spun slowly with nothing added, forming a fibrin scaffold that releases them over seven to ten days and retains stem cells that PRP processing discards. For facial skin regeneration we consider the sustained release the better mechanism.
PRP or PRF for hair — which is better?+
We use PRF. A hair follicle's growth cycle runs over weeks, so a gradual seven to ten day release suits it better than a single burst within twenty-four hours. PRF also retains stem cells and white blood cells that PRP processing separates out. Both are used clinically; PRF is the more recent evolution.
Under-eyes
What is PRF under-eye treatment?+
PRF injected into the tear trough to improve skin thickness, circulation and quality in the thinnest skin on the body. It softens hollowing and dark circles gradually rather than filling them, and because it is your own blood it carries no risk of the blue-grey Tyndall tint that superficial filler can cause here.
How much does PRF under the eyes cost?+
Priced per session and quoted at consultation, generally $500 to $900 a session in Scottsdale. Most patients need two to three sessions spaced four to six weeks apart, and we quote the full course upfront.
How long does PRF under the eyes last?+
Typically 12 to 18 months. Results build gradually over the course rather than appearing immediately, and most patients return for a single maintenance session annually.
What are the side effects of PRF under the eyes?+
Firm swelling for two to four days is expected and is more pronounced than with hyaluronic acid filler. Bruising, tenderness and small lumps that settle are also common. Because PRF is your own blood there is no allergy risk — but equally it cannot be dissolved, unlike hyaluronic acid.
How much swelling is normal after PRF under the eyes?+
A noticeable, firm swelling that peaks at 24 to 72 hours and settles by day four to seven. Patients often describe it as a small pad under each eye. It is the fibrin matrix in place before the tissue absorbs it, and it is expected.
Hair
Does PRF work for hair loss?+
It works where follicles are miniaturising — becoming finer, shorter and lighter — by improving blood supply and extending the growth phase. It does nothing where the follicle has been lost entirely. Timing is the most important variable, and early treatment substantially outperforms late.
Safety
Can PRF be dissolved?+
No. Unlike hyaluronic acid filler there is no reversal agent, because PRF is your own tissue. This is why we treat conservatively and build across sessions rather than attempting everything at once.
Is PRF safe?+
It is among the safest injectables available, because it contains nothing but your own blood — no synthetic material, no additives and no allergy risk. The usual injection risks of bruising, swelling and infection still apply.
Who should not have PRF?+
Anyone with a platelet or bleeding disorder, anyone on anticoagulants without physician clearance, anyone with an active infection, anyone with certain blood-borne conditions or active cancers, and anyone pregnant or breastfeeding.
Location
Do you treat patients from Paradise Valley?+
Frequently. Our clinic is on 69th Street just south of Shea — inside Scottsdale, a few hundred yards from the Paradise Valley boundary, usually a five to ten minute drive from most of PV.
Where in Scottsdale are you located?+
10505 N 69th Street, Suite 1300, Scottsdale, AZ 85253 — at 69th Street just south of Shea Boulevard, with free private parking. We are appointment only.

A proper assessment of what is actually causing your concern — thin skin, lost volume or pigment are three different problems — and an honest answer about whether PRF is the right treatment.
Nervous about the blood draw?
It is a small draw, much like routine bloodwork, and takes under a minute. The centrifuge runs while your numbing cream works, so it adds nothing to your appointment time.
Put off by the wait for results?
Fair — nothing is visible for about four weeks and the full result takes two to three months. If you need a change sooner, filler is the honest answer and we will say so.
Not sure whether you need PRF or filler under your eyes?
That is exactly what the consultation decides. Hollowing from lost volume needs filler; darkness from thin skin needs PRF; pigment needs neither. Many patients have a combination.
Worried it is too late for your hair?
It might be, and we will tell you honestly. PRF works on follicles that are thinning rather than gone. If you are past that point we would rather refer you than sell you a course.
