Nanofat: What It Is and How I Use It in Facial Rejuvenation

One of the biggest misconceptions in facial rejuvenation is that every treatment has to add volume.

It doesn't.

A lot of patients hear the word fat and immediately think, I don't want a fat face. That's a reasonable reaction. It's also the wrong frame for nanofat. As Dr. Grady Core explains it, “Nanofat is completely different. We use it for rejuvenation, not volume.”

At Core Plastic Surgery in Birmingham, nanofat is used to help the skin regenerate. The fat comes from the patient, is processed into a finer form than regular fat grafting, and is placed into the skin using microneedling or other methods. This supports skin quality instead of changing facial shape. Dr. Core is known for his experience in minimally invasive plastic surgery, and he sees nanofat as a practical way to improve aging skin, not just a trendy treatment.

Volume is one problem. Skin is another.

A lot of facial rejuvenation gets flattened into a single question: how do you look younger without looking done? In reality, that question usually contains several smaller ones. Is the problem descent? Is it volume loss? Is it skin texture? Is it etched-in lines around the mouth? Is it darkening under the eyes? Those aren't interchangeable issues, and they shouldn't be treated as though they're.

That's where nanofat becomes useful, conceptually. It isn't there to replace every other category of facial treatment. It's there because skin quality can become its own problem. A patient may have decent structure and still feel that the skin around the mouth looks creased and tired. Another may have lower eyelid hollowing, but the more stubborn complaint is the crepey texture or discoloration sitting on top of it. In those situations, adding volume alone doesn't solve the right problem.

Dr. Core explains nanofat in plain terms: fat is harvested, broken down “to the molecular level,” and then used in the skin for rejuvenation. His phrasing is intentionally practical. “We're just putting fat into the dermis itself. So, this isn't a volumizing procedure.” The goal, in his view, is to place back “building blocks that the dermis can use to rebuild itself.”

That general approach has been studied, though the literature is still relatively small. The 2018 randomized case-control study on facial rejuvenation enrolled 12 women with moderate to severe facial rhytides and compared nanofat treatment on one side of the face with saline on the other. The authors reported a statistically significant reduction in wrinkle severity and improvement in skin quality on the treated side.

That doesn't make nanofat a settled answer to every skin problem. It makes it more than a buzzword.

Around the mouth, the complaints are usually specific

The most revealing part of Dr. Core’s commentary on nanofat is how often he returns to the perioral region. This isn't abstract anti-aging language. It's a very particular part of the face, and patients tend to describe it in concrete terms. “Probably one of the most common questions we get,” he says, “when we say, you know, what seems to bother you the most? They all say the lines around my mouth.” He points to a familiar detail: lipstick that starts to bleed upward into the lip lines.

That's a useful clinical observation because it reflects how aging is actually experienced. Patients aren't usually fixated on a textbook category. They're reacting to a daily annoyance that makeup has started to expose instead of hiding.

Dr. Core also makes a more specific point about who tends to notice this first. “In women, the perioral region seems to be an area that ages very rapidly starting in the 30s,” he says, attributing that pattern largely to estrogen effects combined with sun damage. That is his clinical read, and it helps explain why the mouth becomes such a frequent target for skin-quality treatment. He describes focusing on the lip border, the corners of the mouth, and adjacent fold areas, trying to “rebuild the dermis.”

This is an important distinction in facial rejuvenation generally. A facelift can reposition tissue. It doesn't directly fix the etched surface change. Professional guidance from the American Society of Plastic Surgeons similarly separates skin rejuvenation concerns, such as texture, fine lines, and sun damage, from lifting procedures alone.

Why Dr. Core uses it with microneedling and laser

Nanofat isn't usually presented by Dr. Core as a standalone miracle. He talks about it as part of a broader regenerative plan.

Dr. Core often uses nanofat with microneedling and laser because he sees it as additive, not substitutive. The laser does one job. The nanofat does another. His goal is to place the refined components of the patient’s own fat into the dermis through microneedling, particularly in areas where skin quality has started to decline.

That places nanofat where it probably belongs clinically. Not as a replacement for resurfacing when resurfacing is indicated, but as an adjunct meant to support skin repair and regeneration.

The published literature lines up with that broader idea. A 2023 randomized comparative clinical trial looked at autologous fat transfer with nanofat versus platelet-rich plasma for infraorbital dark circles in 30 patients. The study evaluated outcomes over time and treated nanofat as a targeted tissue-based option for under-eye skin quality and discoloration.

A 2025 systematic review in Aesthetic Surgery Journal Open Forum evaluated nanofat in the management of skin scars, and like much of the literature in this area, the evidence remains limited and heterogeneous. That suggests nanofat should be discussed as a developing regenerative tool, not as a settled universal answer. Dr. Core’s own view is narrower than that anyway: he uses it as an additive treatment, particularly alongside microneedling and laser.

Your own tissue is the point

Regenerative aesthetics often gets buried under terminology. Stromal fraction. biologics. signaling molecules. exosomes. growth factors. The language gets technical fast, and sometimes that obscures the simplest reason certain treatments appeal to both surgeons and patients.

“The neat thing about it is you are using your own tissue,” Dr. Core says. “This is not something that was developed in a lab or something like that. This is actually your own tissue that is being used to rebuild your own skin.”

That's a strong statement of philosophy, and it helps explain why nanofat has gained traction in some aesthetic circles. It's autologous. It comes from the patient. That doesn't mean it works equally well in every application, and it doesn't remove the need for judgment, processing technique, or careful patient selection. But it does place nanofat in a different conceptual bucket from off-the-shelf products.

The available reviews support that framing. Recent overviews describe nanofat as an autologous product derived from mechanically processed adipose tissue and used in wound healing, scar management, and facial skin rejuvenation research. At the same time, these reviews repeatedly emphasize the need for more standardized protocols and larger studies.

That combination of promise and restraint feels appropriate here. Dr. Core’s language is confident, but it isn't mystical. He isn't claiming nanofat replaces surgery. He isn't claiming it replaces lasers. He isn't even claiming it replaces standard fat grafting when volume loss is the real issue. He's saying it has a role when the skin itself needs better raw material.

The most useful way to think about nanofat

Nanofat makes more sense when it is understood as a skin-quality treatment derived from fat, not as a filler alternative and not as a catchall fix.

If the issue is hollowing, that may call for traditional fat grafting or another volumizing strategy. If the issue is tissue descent, that may call for surgery. If the issue is surface change, etched lines, under-eye discoloration, or dermal quality, nanofat may have a role. The treatment only sounds confusing when all of those problems are collapsed into one.

Dr. Core says a “little bit of fat will go a long way,” and that is probably the right note to end on. Nanofat is not about putting more in. It is about putting the right material in the right place.

For patients in Birmingham trying to sort through regenerative facial treatments, that is the clearer frame. Nanofat is not there to make the face fuller. It is there to support rejuvenation at the level of the skin, often in areas such as the mouth and lower eyelids where the skin itself starts to show age first. The published evidence is real, though still developing. The clinical rationale is straightforward. And the treatment makes the most sense when it is used with precision rather than hype.
