Everything You Need to Know About NanoFat in Geneva

Stem Cells and Nano-Fat in Aesthetic Medicine: Definition

NanoFat is an adipose tissue (fat) preparation obtained through liposuction, then mechanically emulsified and filtered to produce a suspension rich in stromal vascular fraction (SVF) and adipose-derived stem cells (ADSCs), while containing very few viable adipocytes.

Objective: To harness the trophic factors, cytokines, and regenerative cells contained within the liquid fraction to improve skin quality (texture, firmness, wound healing), rather than to achieve volumetric augmentation.

Science, Indications, Protocols and Current Limitations

1. Introduction: From Volumization to Regeneration

Modern aesthetic medicine no longer aims solely to fill or tighten — it aims to regenerate.

In this paradigm shift, adipose-derived stem cells and the NanoFat technique play a central role.

While fillers such as hyaluronic acid primarily restore volume, regenerative approaches seek to improve:

• Dermal quality

• Skin density

• Texture

• Vascularization

• Pigmentation

• Tissue repair

This evolving field is now referred to as regenerative aesthetic medicine.

​

2. Stem Cells: Definition and Types

Stem cells are undifferentiated cells capable of:

Self-renewal

Differentiation into multiple cell lineages

In aesthetic medicine, the focus is primarily on:

➤ Mesenchymal Stem Cells (MSCs)

These are mainly derived from adipose tissue.

They exhibit:

Strong paracrine activity (growth factor secretion)

Anti-inflammatory properties

Pro-angiogenic effects

Dermal regenerative potential

​

3. Why Adipose Tissue?

Adipose tissue is:

• Easily accessible

• Rich in stem cells (significantly more than bone marrow)

• Autologous (therefore no immunologic risk)

• It contains the stromal vascular fraction (SVF), which includes:

• Mesenchymal stem cells

• Endothelial cells

• Pericytes

• Macrophages

• Growth factors

• ​

4. Nano-Fat: Principle and Technique

The Nano-Fat technique was first described by Tonnard and Verpaele in 2013.

Unlike conventional lipofilling (macro-fat or micro-fat), which restores volume, Nano-Fat is:

• Mechanically emulsified

• Finely filtered

• Injected superficially

• It contains virtually no viable adipocytes but preserves:

• Stromal cells

• Stem cells

• Growth factors

​

Technical Steps:

Harvesting via micro-lipoaspiration

Mechanical emulsification (repeated syringe-to-syringe passages)

Fine filtration

Superficial intradermal injection

​

5. Indications in Aesthetic Medicine

✔ Pigmented or fine hollow dark circles
Improvement of peri-orbital skin quality.

✔ Thin and crepey skin
Neck, décolleté, hands.

✔ Acne scars
Progressive improvement in skin texture.

✔ Dyschromia
Potential benefit in certain hyperpigmentation disorders.

✔ Post-inflammatory sequelae
Post-acne, post-laser treatments.

​

6. Mechanisms of Action

The primary effect is not volumetric but regenerative:

➤ Paracrine Effect

Secretion of:

VEGF

TGF-β

FGF

Anti-inflammatory cytokines

➤ Fibroblast Stimulation

Increased synthesis of type I and III collagen.

➤ Neoangiogenesis

Improved tissue oxygenation.

➤ Progressive Dermal Remodeling

Clinical results typically become apparent between 6 weeks and 6 months.

​

7. Nano-Fat vs Hyaluronic Acid

Nano-Fat and hyaluronic acid serve different purposes.

Nano-Fat → Regenerative approach

Hyaluronic acid → Immediate volumetric correction

They are complementary techniques rather than competing modalities.

​

​

8. Current Scientific Evidence

Published data demonstrate:

Histologic dermal improvement

Increased skin thickness

Improvement in scarring

Effects on pigmentation

However:

⚠ Protocols are not yet fully standardized.
⚠ Stem cell concentration varies depending on processing technique.
⚠ Regulatory frameworks differ between countries (particularly regarding enzymatic isolation of cells).

9. Limitations and Precautions

Requires a surgical setting

More invasive than injectable fillers

Results are not immediate

Higher cost

Inter-individual variability

Contraindications:

Coagulation disorders

Local infection

Active autoimmune disease

​

10. Future Applications

• Current research focuses on:

• Combination of Nano-Fat with PRP

• Enrichment with concentrated SVF

• Regenerative dermal matrices

• Tissue bioengineering

• Treatment of alopecia

• The boundary between plastic surgery, dermatology, and biotechnology continues to narrow.

​

11. Conclusion

Adipose-derived stem cells and the Nano-Fat technique represent a major advancement in regenerative aesthetic medicine.

They do not replace conventional treatments, but:

✔ Improve overall skin quality
✔ Enhance surgical outcomes
✔ Pave the way for a more biologic aesthetic approach

The future of aesthetic medicine will likely be not only volumetric, but regenerative and personalized.
