YOU by Acorn at Southwest Plastic Surgery: Banking Your Cells, Bottling Your Secretome, and Why It Belongs Next to Morpheus8

A vial of personalized YOU by Acorn secretome serum derived from the growth factors and proteins produced by the patient's own hair follicle mesenchymal stem cells, applied through microneedling, Morpheus8, or fractional laser microchannels at Southwest Plastic Surgery in El Paso, Texas, with Dr. Frank Agullo, MD, FACS, double board-certified plastic surgeon.

If you have walked through the doors at Southwest Plastic Surgery in the last few months, you may have noticed a small refrigerated case at the MedSpa station that was not there a year ago. Inside are personalized vials, each labeled with a single patient’s name, holding a serum that did not exist on the United States market until very recently.

The product is called YOU by Acorn. Each patient’s vials are made from the growth factors and proteins produced by their own hair follicle mesenchymal stem cells. The cells are collected at our MedSpa, shipped to Acorn Biolabs (a Canadian company that runs its lab in California), expanded and stressed in culture for fifteen days, and the secretome they produce is what comes back as that patient’s personal serum. Our medical director, Dr. Frank Agullo, MD, FACS, has been using it on his patients (and on himself) since the start of the year. We sat down with him to walk through what the product actually is, where it sits among the regenerative options on the market, and why the practice has folded it into our MedSpa programs alongside Morpheus8, microneedling, and hair restoration.

So What Does Secretome Mean, Really?

“Look, the first generation of stem cell hype got the basic idea wrong,” Dr. Agullo said. “People thought you’d put stem cells in someone and they’d turn into the tissue you wanted. They don’t, mostly. What they actually do, when they’re alive in the body, is read the room. They sense what the surrounding tissue needs, and they secrete the signals to make that tissue healthier. That secretion, the whole package of it, is the secretome.”

Concretely, that package includes growth factors, cytokines, collagens, proteins, and exosomes (the carriers). All in the proportions a patient’s own cells produced when they were stressed in a lab.

A point Dr. Agullo wants to be very clear on, because patients keep asking: the bottle is the secretome, not the cells. “The vial doesn’t contain stem cells. It contains everything those cells made when we put them to work. The cells themselves are banked separately, frozen, stored as the patient’s property. Two different products from one collection.”

The signal that matters is autologous. “It’s yours. It comes from cells we collected from you. There’s no donor. There’s no rejection risk. Your body already recognizes everything in the bottle as part of you.”

Where the Cells Come From (and Why Fifty Hairs Is Enough)

There are three ways clinicians have historically tried to harvest mesenchymal stem cells. Aspirating the iliac crest, which is painful. Pulling them out of liposuctioned adipose tissue, where they are surrounded by oils and difficult to isolate. Or, more recently, plucking them from the base of hair follicles. That third option is the one Acorn built its platform around.

“There are roughly 1,500 to 4,500 mesenchymal stem cells at the base of every one of your follicles,” Dr. Agullo said. “We pluck about fifty hairs from the back of the scalp, where the nerve density is forgiving. The lab needs about twenty-seven viable follicles to bank a patient. Fifty gives the lab enough cushion to get a clean run.”

Patients keep telling us, somewhat sheepishly, that the collection is the easiest part of the visit. Dr. Agullo agreed, with a laugh: “Honestly, this is the least painful thing that happens at our clinic. Let’s be real.”

What Ends Up in Each Vial

A first-time YOU by Acorn collection produces a personalized batch of twelve 2cc vials, refrigerated, ready for use over multiple visits. (For patients who are not sure they want to commit to the full course, the lab also offers a six-vial entry option.)

The published characterizations Acorn shares with prescribing clinicians:

That is the full FDA-cleared use case as of this writing. YOU is not an injectable. The product is delivered into the brief few-hour window after a procedure has opened thousands of microchannels into the dermis or scalp.

How It Stacks Up Against PRP, PRF, Recombinant PDGF, and Generic Exosomes

This is the table the team uses with patients in MedSpa consults. It is also the cleanest way to see why Dr. Agullo changed his mind about generic exosomes.

What it is Source Blood draw? Dose consistency Where it fits at SWPS in 2026
PRP (platelet-rich plasma) Patient’s own blood, single spin Yes Drops measurably with age and patient health on the day of draw Reasonable for younger, healthier patients. We still use it.
PRF (platelet-rich fibrin) Patient’s own blood, slower spin Yes Slightly more consistent than PRP. Less age-dependent. Useful scaffold for under-eye and orthopedic indications.
Recombinant pure PDGF (Ariessence pure PDGF+) Recombinant rhPDGF-BB in HA No Identical dose every kit Excellent post-microneedling topical when one specific signal at a controlled dose is the goal.
Generic donor exosomes Cultured donor stem cell media, often filtered to exosomes only No Rarely characterized. Carriers without published payload. Not used at SWPS.
YOU by Acorn secretome Patient’s own follicle-derived mesenchymal stem cells, expanded and stressed in lab. Bottle is the secretome only; cells are banked separately. No (one painless follicle pluck) The same biology the patient’s body produces, concentrated, characterized Default for patients who want the broadest, most personalized regenerative signal currently available, applied through microneedling, Morpheus8, or fractional laser channels.

“Honestly, the generic exosome conversation is the one I’m happiest to retire,” Dr. Agullo said. “An exosome by itself is a carrier. An empty Easter egg unless you actually know what’s loaded inside it. Most exosome bottles ship the carriers without the surrounding signal, and without published assays of the payload. With YOU, we have both. The carriers, the cargo, and the data.”

Where It Fits in Our MedSpa, Treatment by Treatment

YOU is a topical that requires microchannels in the skin or scalp to reach the compartment that responds to it. The currently FDA-cleared applications are post-microneedling, post-Morpheus8 RF microneedling, post-fractional laser, on the face, and post-microneedling on the scalp for hair. That is where most patients first encounter the product.

For Morpheus8 RF microneedling, the team typically reconstitutes two YOU vials with the topical-grade hyaluronic acid that ships with the kit, and the secretome solution is applied immediately after the radiofrequency pass and rolled or microneedled into the freshly opened channels. Patients can take a small dropper home and continue topical application twice a day while the channels are still open. The recovery window has been visibly shorter for patients on this protocol.

For fractional laser resurfacing and decollete work, twelve vials disappear quickly, and the post-procedure recovery profile has been consistent with what we see on Morpheus8.

For hair restoration, we use YOU for Hair as a microneedled scalp treatment in series. Patients already invested in PRP or PRF for hair do not have to choose between regimens. We layer the secretome into their existing schedule for one or two sessions and let them tell us what they prefer once they have seen both.

A Surgical Sidebar: Dr. Agullo’s Own Experiment

For patients curious about what the protocol actually looks like in practice, Dr. Agullo has been candid about running it on himself before recommending anything to patients.

“I’m fifty-two,” he said. “I’ve been on GLP-1s for about a year. Lost roughly thirty pounds. There’s no question my skin would have lost more elasticity than it has if I hadn’t been keeping up with my MedSpa protocol. So I scheduled a Morpheus8 session in my own clinic, microneedled two cc of YOU by Acorn into the freshly channeled tissue, and went home. One week later, my wife noticed. She said my face looked better than it had a week earlier. Morpheus8 alone is good. Morpheus8 with YOU was different. The recovery was visibly faster, and the skin quality at one week looked like what I would have expected at three weeks.”

Cell Banking, and Why Patients Are Signing Up at Any Age

Every YOU by Acorn collection cryopreserves one quarter of the patient’s mesenchymal stem cells. Those cells are stored at the age the patient was on the day of collection, and they remain the patient’s property. Acorn’s banking subscription includes individual and family options.

For patients reading this who are wondering whether they are too old, Dr. Agullo’s clinical answer is encouraging: “We’ve banked patients as old as eighty-two. As long as the lab confirms viable stem cells in the collection, age is not a hard limit. The product isn’t reversing the biological clock. But the secretome we generate from the youngest banked version of you is, by definition, the youngest version of your own signaling we can still get our hands on.”

Acorn’s lab can also induce banked mesenchymal stem cells back into a pluripotent state and derive lineages including bone, cartilage, pancreatic cells, neurons, and natural killer cells. The clinical translation of that work is years away. The bank, in the meantime, gives patients the option to make their own cells available, with their consent, to future therapies derived from their own biology.

Where MedSpa Fits, and Where It Does Not

YOU by Acorn lives in our MedSpa programs, paired with Morpheus8, microneedling, fractional laser, ElixirMD post-procedure recovery, and our hair restoration protocols. It is not a substitute for sunscreen, a retinoid, or the procedure itself. And it is not, in Dr. Agullo’s framing, a turn-back-the-clock product.

For the patient whose conversation needs to start with surgery rather than MedSpa (a deep plane facelift, a Ponytail Lift, a breast preservation program, a body contouring plan), YOU is a complement on the recovery side rather than the answer. The team will tell you that directly in the consult.

The Growth Factor Replacing PRP After Microneedling: Dr. Frank Agullo on Ariessence Pure PDGF+

A patient receives radiofrequency microneedling at the cheek with a pen-style device at the Southwest Plastic Surgery MedSpa, illustrating the post-procedure window when topical recombinant pure PDGF (Ariessence pure PDGF+) is applied. Reviewed by Dr. Frank Agullo, MD, FACS, double board-certified plastic surgeon in El Paso, Texas.

For about five years, every Morpheus8 appointment at our El Paso MedSpa started the same way. Patient checks in. Vitals. A small tube of blood drawn from the inside of the elbow. The tube goes into a centrifuge. Twelve minutes later, our team paints platelet-rich plasma onto freshly microneedled skin. Patient leaves with a small bandage on the inner arm and (usually) a glow.

Then, sometime around the start of the year, the routine changed. The blood draw disappeared. The bandage on the arm disappeared. Patients started asking the obvious question. What happened to the PRP.

We took the question to Dr. Frank Agullo, the medical director of Southwest Plastic Surgery. He has been running this MedSpa long enough to remember when PRP was the new exciting thing nobody had heard of. He gave us the long answer.

The shorthand version

“PRP works,” Dr. Agullo told us. “It still works. We did not stop because PRP failed. We stopped because something cleaner showed up. Recombinant pure PDGF, in a controlled dose, with no blood draw. The brand we use is Ariessence pure PDGF+.”

The longer version of that explanation is worth a few minutes. The MedSpa team has been getting a version of this question every week since the change, and the answer is genuinely interesting once a patient takes the time to hear it.

What is PDGF, in plain English

The body has a small set of proteins it relies on to handle injury. When tissue gets cut, scraped, microneedled, lasered, or otherwise irritated, platelets release a cocktail of proteins called growth factors. PDGF is one of the leaders of that cocktail. It calls in the cells that lay down new collagen. It helps the body build the new blood vessels healing tissue needs. It is, in a real sense, the molecule the dermis is asking for at the exact moment it just got injured.

For most of the past decade, the way clinicians delivered PDGF to skin in an aesthetic context was indirect. They drew a tube of patient blood, spun it down in a centrifuge, and applied platelet-rich plasma on freshly microneedled or lasered skin. PDGF rode along, mixed with several dozen other proteins, in concentrations that varied with the patient and the technician.

Recombinant pure PDGF is what you get when a lab makes only the PDGF molecule itself. The protein is produced in cultured cells from a human gene, then purified to a single active species. The dose is the same in every patient. There are no human-derived components in the formulation. The Ariessence product pairs the recombinant PDGF with a hyaluronic acid serum and is mixed in the treatment room in under a minute.

“Same idea as PRP,” Dr. Agullo said. “Just a cleaner version of the same idea. The thing the body was asking for, in a controlled amount, every time.”

Why right after a microneedling session, and not as a take-home serum

Patients ask if Ariessence is something they can buy and apply at home. The answer is no, and the reason is mechanical.

PDGF on intact skin sits on top of the stratum corneum. The stratum corneum is the skin’s outer barrier. It is highly effective at keeping large molecules out. A growth factor in a jar at home is mostly a moisturizer with an interesting label.

The post-procedure window changes that. After Morpheus8, RF microneedling, fractional laser, or a medium-depth peel, the skin has thousands of microchannels open into the dermis for a finite period. The treatment area is briefly ready to receive what gets applied to it.

“That window closes inside a couple of hours,” Dr. Agullo said. “Whatever I put on the skin in the first ten minutes is the second half of the procedure. We do not waste it on water.”

The study patients keep asking about

In September 2025, Michael Gold and colleagues published a randomized controlled trial in the Journal of Cosmetic Dermatology. Healthy adults between thirty and sixty got a single Morpheus8 RF microneedling session. They were randomized to receive either bland Aquaphor or topical recombinant pure PDGF-BB immediately after. A blinded evaluator graded them at seven and thirty days using a global aesthetic score, the Canfield Visia imaging system, and patient experience surveys.

The PDGF group did better on the global aesthetic score at thirty days. The result was statistically significant. The PDGF group came out ahead on six of the seven Visia metrics. Patient experience favored the PDGF group across the experience measures. No serious adverse events were reported.

We asked Dr. Agullo for his read.

“Two reads at the same time,” he said. “Patients deserve both.”

He started with the honest read. Topical recombinant pure PDGF after RF microneedling beat a bland emollient on the measures that matter for skin rejuvenation. The margin was not subtle.

Then the careful read. The manufacturer puts a disclaimer in writing. The exact formulation tested in the trial is not identical to the marketed Ariessence bottle.

“So I do not tell my patients the trial proves the bottle,” he said. “I tell them the science of the category is real, the trial supports the approach, and the bottle on our shelf is the closest commercial expression of that science right now. Both things are true. Better they hear it from me than from a Reddit thread at 2 in the morning.”

Where Ariessence sits next to PRP, PRF, and exosomes

The MedSpa team is asked about all of these in roughly the same week. Here is the comparison Dr. Agullo had us put together.

Modality Source Blood draw Dose predictability 2026 role at our MedSpa
Aquaphor Petroleum jelly No Total, but no biological signal Default barrier, used after most procedures
PRP Patient blood, single-spin Yes Variable patient to patient Available on request, not the default
PRF Patient blood, slower spin Yes Slightly more consistent than PRP Not currently in rotation
Exosomes Stem cell conditioned media (donor) No Manufacturer-dependent, regulatory uncertainty Not in rotation
Ariessence pure PDGF+ Recombinant rhPDGF-BB in HA serum No Identical dose every kit Default after Morpheus8, RF microneedling, fractional laser, or medium-depth peel

“That table changed in our practice this year,” Dr. Agullo told us. “It will change again. The right answer to a patient’s question is whatever the most current science supports. I am not married to a tray.”

Where MedSpa fits, and where it does not

A version of one question shows up in our consultations every week, particularly with patients in their forties and fifties. How far can MedSpa take me, the question goes, before I really do need to think about surgery.

Dr. Agullo’s answer has been more or less the same for years.

“Our MedSpa has real tools, not props,” he said. “Botox, hyaluronic acid fillers, BBL Forever Young, laser resurfacing, Morpheus8 RF microneedling, chemical peels, and now Ariessence on top of all of those for cleaner recovery. Every one of them earns its keep. On a forty-year-old face the whole toolbox can buy years before surgery is the right move. The catch is that none of those tools repositions deep tissue. They treat surface, volume, and tone. Try to use them as a permanent stand-in for a facelift on a face that has actually descended, and what you get is not a younger face. You get a fuller one. Puffy cheeks, no jawline, an upper lip nobody asked for. We call that the filler tax.”

He spends almost as much time on sequencing.

“In your forties and early fifties, lean into MedSpa. Be sparing and precise with injectables. The day structure actually starts to slip is the day to be sitting at a surgery consultation. Earlier than later. After the facelift heals, MedSpa picks back up. Skin care, energy-based treatments, growth factors after each procedure for faster recovery, and small injectables on a careful cadence. Not a wall of syringes.”

That arc is something the surgical team and the MedSpa team plan together for facelift patients. It is one of the reasons our practice draws patients from out of state for the long view, not just one operation.

What patients should ask about Ariessence specifically

We asked Dr. Agullo what questions he wishes patients would put to any provider who is offering Ariessence, or for that matter any other growth-factor adjunct.

He came back with four.

First, what procedure are they pairing it with? The right answers are Morpheus8, RF microneedling, fractional laser, or a medium-depth peel. If the provider tells you “oh, you can just take it home and apply it daily,” he says, walk out.

Second, how fast is it going on after the procedure ends, and how is the kit being mixed in front of you? Within roughly ten minutes is what you want. Hours later is past the point where it does much.

Third, what is the dose, and where does the protein come from? Recombinant pure PDGF-BB, controlled concentration, no human-derived material, is the standard he wants you to ask the provider to confirm. Vague answers there are a red flag.

Fourth, is the product being marketed and used as a topical cosmetic, or is somebody quietly offering to inject it? Topical cosmetic is the entire regulatory category for this product. A provider offering to inject it has decided to operate outside that category, and that is not a position you want a stranger making on your face.

What it is not, said cleanly

Ariessence pure PDGF+ is sold as a topical cosmetic. It is not an FDA-approved drug. It is not approved to diagnose, treat, cure, or prevent any disease or condition. It is not for injection. The four FDA-approved drug products that contain PDGF (GEM 21S, Augment, Augment Injectable, Regranex) are unrelated formulations approved for non-cosmetic medical indications. Their long safety record informs the molecule’s general safety profile, but does not transfer regulatory approval to the cosmetic.

The MedSpa is clear about this with every patient. So is Dr. Agullo. So is the manufacturer.
