Regenerative Medicine in Plastic Surgery: The Work of Dr. Greg Chernoff
Regenerative medicine in plastic surgery is rapidly changing what’s possible for patients with scars, acne, and aging skin. At the forefront of this movement is Dr. Greg Chernoff, a plastic surgeon with over 34 years of experience in esthetic, plastic, and reconstructive surgery—and more than 30 years in cellular medicine.
In this episode, Dr. Chernoff explains how stem cells, exosomes, and advanced scaffolding technologies are helping patients achieve better healing, fewer recurrences of keloids, and profound improvements in self-esteem.
From Cancer Surgery to Cellular Medicine
Before focusing on cosmetic surgery, Dr. Chernoff performed complex head and neck cancer surgeries on patients who often continued to smoke and drink despite treatment. After seeing many of them die within a few years, one pivotal moment—catching a tracheotomy patient smoking through the trach—convinced him to shift his focus.
Today:
- His clinical work is 100% esthetic plastic and reconstructive surgery
- 25% of his practice is dedicated to research in regenerative medicine
- He founded the Survivors of Violence Foundation, donating surgery to battered spouses and survivors of violence, giving him extensive experience in scar and wound healing
This combination of clinical work, trauma care, and research laid the groundwork for his innovations in cellular medicine.
Early Work: Autologous Cellular Therapies
Dr. Chernoff’s journey into cellular medicine began in the late 1980s and early 1990s with autologous therapies—treatments that use a patient’s own cells.
His early protocol included:
- Taking post-auricular skin biopsies (from behind the ear)
- Culturing and expanding fibroblasts
- Cryopreserving these cells
- Re-injecting them into facial folds, lips, and scars
This work led to one of the first FDA-approved autologous injectable fibroblast therapies in aesthetic medicine and paved the way for future stem cell–based treatments.
He later collaborated with Dr. Mark Berman on autologous fat-derived stem cells, publishing:
- A paper on injectable fibroblasts (2000)
- A paper on autologous fat-derived stem cells in facial plastic surgery
These early publications helped define how stem cell therapy in plastic surgery could safely be integrated into clinical practice.
Exosomes and Placental Stem Cell–Derived Therapies
As regulatory pathways for autologous fat-derived stem cells stalled, Dr. Chernoff began searching for an off-the-shelf form of cellular medicine that aligned with FDA guidelines.
This led to his work with human placental mesenchymal stem cell–derived exosomes, in collaboration with Duncan Ross of Chimera Lab.
Over the last 7+ years, his team has treated nearly 800 patients with exosomes in plastic surgery, focusing on:
- Aging skin
- Chronic acne
- Wound care
- Scar therapy, including keloid scars
These exosome therapies for skin are showing powerful results, especially when combined with advanced scaffolding and delivery systems.
Keloid Scar Treatment: From 100% Recurrence to Under 1%
One of the most dramatic applications of regenerative medicine in plastic surgery is in keloid scar treatment.
Traditionally, surgically removing a keloid resulted in:
- Near-100% recurrence rates
By integrating exosomes and scaffolds, Dr. Chernoff’s protocol now involves:
- Excision of the keloid
- Application of an amniotic membrane graft over the treated area
- Flooding the graft with exosomes to support regenerative healing
Results so far:
- Recurrence rates reduced to under 1%
- More than 50 patients followed for close to five years without recurrence
For patients with large, disfiguring keloids on the ears, chest, or other visible areas, this approach can be life-changing—not only cosmetically, but psychologically.
Stromal Vascular Fraction (SVF) and Automated Fat Processing
Another key tool in Dr. Chernoff’s practice is stromal vascular fraction (SVF), derived from a patient’s own fat.
Thanks to modern automated devices, the process can now be completed in about 45 minutes, often in a single operative session:
- Harvest about 100 cc of fat
- Process it with enzymes in closed, automated systems
- Isolate the stromal vascular fraction, rich in regenerative cells
- Deploy these cells based on the patient’s specific needs
Although SVF therapy is still working through regulatory pathways in the United States, it remains a major area of research and clinical interest in cellular medicine and stem cell therapy for scars and skin rejuvenation.
Scaffolds and Scarless Healing: Moving Toward Biological Regeneration
To improve how regenerative products stay and act in the body, Dr. Chernoff leverages scaffolding technologies.
Working with Dr. Sherry Harbin at Purdue University, he has used an injectable scaffold sometimes referred to as a “colomer” (columnar) gel:
- Injected initially as a liquid into a wound
- Solidifies into a biogel within about 45 seconds
- Can be pre-loaded with exosomes or other regenerative products
In preclinical studies, tissue defects filled with this scaffold have been replaced over time with normal, regenerated tissue, hinting at the possibility of truly scarless healing.
A key biological model discussed is the axolotl salamander, an animal capable of complete, scarless regeneration. Its healing profile—rapid hemostasis, fast re-epithelialization, and minimal inflammation—explains why controlling inflammation is critical in human wound and scar treatment.
Nitric Oxide and Predictive Permeation: Smarter Topical Delivery
Because many therapies must currently remain topical to comply with FDA regulations, delivery into the skin becomes crucial.
Dr. Chernoff collaborated with Dr. Nathan Bryan, an authority on nitric oxide, to enhance topical absorption:
- An oral nitric oxide lozenge
- Paired with a topical nitric oxide serum
- Creates about a 45-minute “window” of enhanced skin absorption
His team then spent three years developing predictive permeation strategies that allow them to:
- Deliver molecules up to 800 Daltons
- To specific depths within the epidermis and dermis
- Help maximize the effectiveness of topical exosome therapy and other regenerative products
For patients, this means more targeted, safer, and more effective non-invasive treatments for acne, aging, and scarred skin.
Emotional Healing: Self-Esteem, Trauma, and Regenerative Results
Beyond the technical details, one of the most powerful outcomes of regenerative plastic surgery is its impact on self-esteem and trauma recovery.
Dr. Chernoff still treats survivors of:
- Rape at knifepoint
- Domestic violence
- Severe facial and body trauma
For these patients:
- Visible scars are constant reminders of the event
- Passing comments from strangers or children can be deeply wounding
- Their physical scars often mirror—and reinforce—psychological scars
Through exosome therapy, stem cell–based approaches, and advanced scar revision, Dr. Chernoff has seen profound transformations:
- Patients who once avoided eye contact now look straight into the camera
- Formerly withdrawn individuals smile more and engage socially
- Quality of life improves dramatically, not just appearance
This is where regenerative medicine in plastic surgery moves beyond aesthetics into the realm of mental health, identity, and quality of life.
The Future of Regenerative Medicine in Plastic Surgery
According to Dr. Chernoff, the field is still at the “scratching the surface” stage.
He envisions a future where:
- We fully map the microRNAs and messenger RNAs involved in wound healing
- Genetically engineered, patient-specific products are created from simple samples of saliva, blood, or urine
- Exosome diagnostics allow us to:
- Detect cancers and disease states at Stage 0
- Potentially outperform even full-body MRI in sensitivity
On the regulatory and scientific side, he stresses the importance of:
- Standardization
- Well-designed clinical trials
- Ethical data collection and transparent reporting
These principles are essential to advancing the field responsibly and ensuring that regenerative therapies are both safe and effective for patients.
From Fringe to Mainstream: Standing Room Only
Just a few years ago, regenerative medicine sessions at conferences were sparsely attended. Today:
- Rooms are standing room only
- More clinicians are exploring stem cell therapy, exosomes, and SVF
- Patients are increasingly educated and proactive about using their own tissues and regenerative tools
While regulatory approval for some autologous stem-cell–based therapies is still pending, the trajectory is clear: regenerative medicine in plastic surgery is moving rapidly from fringe concept to mainstream, evidence-based practice.
Conclusion: Living Better, Not Just Longer
Regenerative medicine is redefining what’s possible in plastic and reconstructive surgery. Through:
- Stem cells and stromal vascular fraction
- Exosomes for skin and scars
- Advanced scaffolds and predictive permeation
- And a relentless focus on both outcomes and ethics
Dr. Greg Chernoff and his colleagues are helping patients:
- Heal scars more completely
- Avoid keloid recurrence
- Clear chronic, inflammatory acne
- Regain confidence, identity, and quality of life
In a world where people are often judged by outward appearance, these tools don’t just change how someone looks—they can fundamentally change how they feel about themselves and how they move through the world.
