Dual Wavelength 980nm 1470nm Diode Laser Machine for Subdermal Fiber Tightening and Double Chin Slimming

A dual-wavelength diode platform (980nm + 1470nm) delivering micro-fiber interstitial laser energy to selectively emulsify small fat pockets and thermally remodel the subdermal matrix. The 1470nm channel—highly water-selective—creates controlled photothermal heating for collagen denaturation and tightening, while 980nm supports intra-tissue coagulation and hemostasis. The result is precise jawline definition and submental reduction with minimal access points and rapid recovery when performed by qualified clinicians.

1. Product Technical Principle

1.1 Selective Photothermolysis in the Subdermal Plane

• 1470nm (water-selective): Predominant absorption by interstitial water and adipocyte membranes produces homogeneous heating in the pre-platysmal fat and fibroseptal network. Heat-induced denaturation (≈ mid-50s °C intratissue) shortens collagen triple helices; subsequent neocollagenesis drives sustained tightening.

• 980nm (hemoglobin-assisting): Lower water absorption but higher interaction with hemoglobin supports micro-vessel coagulation, reducing oozing during fiber passage and improving visibility and control.

1.2 Micro-Fiber Optic Delivery

Energy is delivered via bi-quartz optical fiber transmission through a blunt introducer. The 200–400μm class micro-fiber (vendor-selectable) emits forward-scattered or slightly divergent light in the subdermal layer. The operator uses fan-shaped pullback passes to create overlapping thermal columns, ensuring even lipolysis and skin contraction.

1.3 Pulse Dynamics & Thermal Dosing

• Modes: Pulse / CW / Single pulse.

• Pulse width (15–100ms) & Frequency (1–20Hz): Allow fine control of thermal relaxation between shots to avoid carbonization while reaching target temperatures for adipocyte disruption and collagen remodeling.

• Practical dosing concept: Tissue temperature is governed by power × dwell time × pass density and pullback speed. Shorter pulses at higher repetition can maintain a stable thermal plateau with less peak charring risk compared to prolonged CW exposure.

• Synergy: Begin sculpting with 1470nm for water-mediated heating and tightening; use 980nm selectively when coagulative support is needed around septa or perforators.

1.4 Macro to Micro Effects

• Micro-level: Fat vacuolization and septal collagen shrinkage.

• Meso-level: Dermal-SMAS envelope tightening and mandibular contour sharpening.

• Macro-level: Visible reduction of submental fullness, crisper cervicomental angle, and improved lower-face definition.

2. Application Scope

2.1 Indications

• Submental adiposity with mild-to-moderate skin laxity.

• Jawline blunting / early jowling where fine-scale debulking and tightening are preferred over suction.

• Retouch after weight loss for soft-tissue redraping.

2.2 Small-Area Body Use

• Peri-knees, upper arms “pinchable” pockets, axillary roll—micro-contouring needs only.

2.3 Candidate Profile

• Stable weight; pinchable submental fat; elastic or mildly lax skin; realistic expectations; willing to follow post-care. Suitable across all skin phototypes given subdermal light delivery.

3. Advantages for Clinics

• Dual-wavelength control: 1470nm tightening + 980nm hemostasis assistance.

• Micro-access points (≈1mm): Reduced invasiveness; typically no suction required.

• Even thermal fields: Pulsed delivery helps avoid hot spots.

• Clean workflow: 650nm pilot beam for fiber tracking; 10.4-inch touchscreen for quick parameter changes.

• Scalable power options: Standard and optional wattages to match operator preference and case complexity.

• Marking & Photos: Define submental triangle, mandibular border, danger zones.

• Asepsis & Local/Tumescent: Infiltrate for analgesia, hydrodissection, and heat sink.

• Access Creation: 18G–19G puncture; insert blunt introducer; advance micro-fiber in subdermal, pre-platysmal plane.

• Energy Delivery:

  • Start with 1470nm, pulsed; slow, even pullbacks in fanning patterns.

  • Use 980nm selectively where micro-coagulation is beneficial.

  • Maintain continuous tissue motion to distribute heat.

• End-points: Palpable softening of fibroseptal network, uniform tissue “butter-like” glide, no surface overheating.

• Closure & Dressing: Steri-strip/compression as per clinic standard.

• Follow-up: Review at 1–2 weeks, then 6–12 weeks for tightening evolution.

5. Pre- and Post-Treatment Notes

Pre-Care

• Discontinue photosensitizing/topical irritants 3–5 days prior per practitioner advice.

• Avoid anticoagulants/NSAIDs if medically permissible and approved by the physician.

• No active infection, dermatitis, or open lesions at the site.

Post-Care

• Compression (as advised) for 24–72h to limit edema.

• Gentle cleansing; avoid hot environments and vigorous exercise for 48–72h.

• Expect transient swelling/tenderness; cold packs (intermittent) as directed.

• Sun protection; delay energy-based surface treatments until cleared by provider.

6. Contraindications

• Pregnancy/lactation; bleeding disorders; unmanaged diabetes; implanted electronic devices near field; photosensitizing medications; keloid-prone history at access sites; active herpes, eczema flare, or bacterial infection on target area.

• Use sterile technique; monitor cumulative energy and tissue response to prevent burns or nerve injury. Facial danger zones (marginal mandibular nerve) require expert anatomy knowledge.

What Outcomes to Expect

• Immediately: Debulking sensation and light edema.

• 4–6 weeks: Progressive skin tightening as neocollagenesis matures.

• 8–12+ weeks: Sharper cervicomental angle, improved jawline definition.
  Outcome timelines vary by patient biology, technique, and post-care compliance.​

Quality & Safety Notes

• 650nm pilot beam enhances fiber tip localization beneath thin cervical skin.

• Pulsed operation with short-to-medium pulse widths helps maintain stable thermal plateaus.

• Dual wavelength availability provides in-treatment flexibility without swapping platforms.

FAQ
