1. What is the ONE S.T.E.P. 1210nm technique

1.1 Definition

Innovation in liposculpture: less trauma, more viable cells, and accelerated healing

The ONE S.T.E.P. 1210nm technique therefore represents an advancement in the field of aesthetic and regenerative plastic surgery, especially in liposuction or liposculpture procedures. Thus, based on the use of a 1210nm wavelength diode laser, it aims to reduce trauma, preserve adipose cells and stem cells, and allow for faster recovery. In this article, we will explain, in a technically accessible way, how it works, its indications, benefits, risks, comparison with conventional techniques, and pre- and post-operative care.

• 🔬 Preservation of adipocytes and stem cells through the 1210nm laser
• 🩹 Less surgical trauma, bruising, and post-operative discomfort
• 📦 Possibility of grafting or use in regenerative medicine with quality fatty tissue
• 📉 Reduction of skin laxity by stimulating collagen and skin retraction
• 🧭 Precise indication: does not automatically replace all liposuctions — individual assessment is fundamental

The ONE S.T.E.P. 1210nm technique (“Selective Tissue Engineering Photostimulation Technique”) uses a 1210nm wavelength laser to act on subcutaneous adipose tissue with an affinity for fats. (“Selective Tissue Engineering Photostimulation Technique”) uses a 1210nm wavelength laser to act on subcutaneous adipose tissue with an affinity for fats.

Unlike traditional liposuction techniques that only aim to remove fat, this technique also incorporates the idea of utilizing aspirated tissue for grafting or regeneration.

1.2 Principle of operation

• The 1210nm laser is introduced through an optical fiber via a fine cannula into the adipose tissue.
• During application, there is selective photostimulation of fat cells and the extracellular matrix, releasing viable adipocytes and stem cells without causing extensive tissue lysis (destruction).
• The aspirated fatty tissue maintains high cellular viability, with viability of adipocytes and stromal vascular fraction (SVF) above 90% in some studies.
• In many cases, the collected tissue can be immediately grafted (lipofilling) or used in regenerative medicine (wounds, reconstructions) without extensive manipulation.

1.3 Difference from other laser techniques

While other liposuction lasers act by emulsifying or thermally destroying fat (conventional laser lipo), the ONE S.T.E.P. 1210nm technique aims not to destroy, but to preserve adipose tissue and its regenerative component.

Furthermore, the selectivity of the 1210nm wavelength favors adipocytes without significantly affecting muscles, nerves, or tissue water, according to expert reports.

2. Indications and clinical applications

2.1 Aesthetic indications

• Conventional liposuction or liposculpture with less trauma.
• Lipofilling (e.g., in buttocks, breasts or other volume areas) with high-quality fatty tissue.
• Body contouring procedures, reduction of skin laxity.

2.2 Regenerative and reconstructive indications

• Tissue regeneration such as skin, subcutaneous tissue, cartilage, mucous membranes as described in the technique materials.
• Breast reconstruction with lipofilling in post-mastectomy patients.
• Treatment of complex wounds, chronic lesions, general regenerative medicine using aspirated fat and derived cells.

2.3 Limitations and patient selection

Like any technique, ONE S.T.E.P. requires careful evaluation: the plastic surgeon must check the patient's clinical condition, presence of excessive laxity, skin quality, volume of fat available for removal/grafting, and general health. It is not indicated as an automatic substitute technique for all liposuction cases.

3. Main benefits

• Less surgical trauma: less bleeding, less edema and bruising, more comfortable recovery.
• Preservation of viable stem cells and adipocytes, which maximizes tissue utilization for grafting or regeneration. Example: authors' study achieved an average of ~15.6 million viable cells per gram of aspirated tissue, viability ~92.5%.
• Improved skin retraction and less laxity, due to photobiomodulatory action that stimulates collagen.
• Versatility: can be applied in aesthetic and reconstructive procedures, a “one-step procedure” according to one of the brochures.
• Fast processing time: according to the study, stromal vascular fraction processing was less than 20 minutes, facilitating immediate grafting.

4. Risks, contraindications and care

4.1 Risks common to liposuction

Even with a more “friendly” technique, typical liposuction risks persist: infection, bleeding, contour irregularities, asymmetries, scars, possibility of residual laxity depending on the skin.

4.2 Specific or potential risks

• Although less invasive, it still requires a cannula, laser, and manipulation — experienced surgeon is needed.
• As it is a relatively new technique, although there are studies, the long-term volume (10-20 years) is still smaller compared to traditional techniques.
• The effectiveness of the technique depends on correct indication and patient’s skin and tissue quality. If there is severe laxity, it may not resolve on its own.

4.3 Contraindications

• Patients with clinical conditions that contraindicate surgery (poor cardiovascular condition, organ failure, clotting problems).
• Patients with unrealistic expectations or who do not accept the use of aspirated fat for grafting or regeneration.
• Areas with very lax or poor quality skin that may require concomitant abdominoplasty or lift.

4.4 Post-operative care

• Compression garment traction as directed by the surgeon.
• Early mobilization, hydration, balanced diet.
• Monitoring for signs of infection, hematoma, or irregularity.
• Monitoring the evolution of skin texture, contour, and grafted area volume (if any).

5. Comparison with conventional liposuction or other laser technologies

Technique	Approach	Cell/adipocyte preservation	Recovery	Ideal for grafting/regeneration
Conventional liposuction (aspiration + cannula)	Mechanical fat removal	Lower preservation, more trauma	May have more bruising/edema	Less ideal
Conventional laser lipo (fat emulsification)	Laser to liquefy fat	Adipocyte destruction may occur	Moderate trauma	Used, but lower tissue quality
ONE S.T.E.P. 1210nm technique	Selective photostimulation + aspiration	High preservation (e.g., ~98% adipocytes, 10-20 million cells/g)	Faster recovery, less bruising	Excellent for grafting/regeneration

Therefore, the ONE S.T.E.P. 1210nm technique stands out precisely by combining fat removal with cell and tissue preservation, opening up both aesthetic and regenerative possibilities.

6. How the procedure is done - simplified step-by-step

1. Pre-operative patient evaluation by the surgeon: exams, contracts, expectations.
2. Marking of fat areas to be removed.
3. Anesthesia (general or local + sedation) as appropriate.
4. Infiltration of the nearest area: solution with adrenaline to minimize bleeding (in study: cold solution + adrenaline 1:500.000)
5. Introduction of the 1210nm laser optical fiber into the deep adipose layer, above the muscular fascia.
6. Laser emission to release fatty tissue by selective photostimulation.
7. Aspiration of fatty tissue with a cannula (generally smaller gauge) preserving cells and matrix.
8. In the case of lipofilling or regeneration, the tissue can be centrifuged and applied according to protocol (e.g., stromal vascular fraction).
9. Finalization, application of drainage or compression according to protocol, and initiation of post-operative care.
10. Follow-up: use of garment, activity restrictions, massage or lymphatic drainage sessions if indicated.

7. Scientific evidence

• Published study compared stromal cells derived through the ONE S.T.E.P. technique with other techniques, showing better cell preservation.
• In a report and technical article, it is stated that the 1210nm laser has selective affinity for adipocytes and promotes hypodermis regeneration.
• Technical brochure from the developing company mentions the possibility of use in grafts and regeneration with “compound graft”.

Although initial results are promising, it is important for the patient to verify long-term data with their surgeon, and for the professional to have proven experience with the technique.

8. Frequently Asked Questions (preview)

• Is this technique appropriate for all patients who want liposuction? Not all. The indication depends on factors such as the volume of fat to be removed, skin quality, expectations, and clinical conditions.
• Can I use the removed tissue for grafting? Yes — this is one of the differentiators: the aspirated tissue, preserved, can be used for grafting or regenerative applications.
• Is it more expensive than traditional lipo? Generally, yes, due to the specific equipment, involved technology, and the need for a trained professional.
• Is the post-operative period much shorter? In many reports, yes — less bruising/edema, less pain, but still requires normal post-liposuction care.
• Is there a greater risk of skin laxity? Every liposuction procedure has this risk if the skin is of poor quality or if there is very extensive removal. The ONE S.T.E.P. technique aims to reduce this risk by stimulating collagen.
• What is the time to see the final result? Generally a few months for contour and up to 6-12 months for complete grafting/regeneration.
• Do I need post-operative compression? Yes — garment or compression bandage as indicated by your surgeon.
• Is it registered with the Brazilian regulatory agency? Some methods with a 1210nm laser are described and mentioned as approved for certain indications (e.g., “Laser Regenera”) locally.
• Can it be used for mild facial or body laxity? Yes — some report using this technology for body or face lifts.
• What are the most common complications? Even with a more advanced technique, contour irregularities, asymmetry, pain, bleeding, small bruises, and the need for touch-ups can occur.

9. Conclusion

The ONE S.T.E.P. 1210nm technique represents an evolution in liposuction and lipofilling by combining fat removal with the preservation of cells and usable tissue for regeneration. For those seeking body contouring or regeneration with cellular quality, it can be an excellent option provided that the surgeon has experience and the patient is well-indicated.

If you are considering plastic surgery or lipofilling, I recommend scheduling a consultation with a plastic surgeon experienced in this technique to assess your case, understand the risks, benefits, and view a portfolio of results.
