Dual-WavelengthLaser Science
The 980nm and 1470nm wavelengths were selected for very specific reasons: selective chromophore absorption and depth of penetration. Used separately or delivered simultaneously, the physician makes anatomically driven wavelength selections for individualized treatment plans.
Wavelength Science
Two Wavelengths, One Precision System
Each wavelength targets specific tissue chromophores at controlled depths, enabling physicians to customize treatments based on anatomical needs.
980nm Wavelength
EraSculpt Mode
The 980nm wavelength has a high affinity for hemoglobin and lipid-rich tissue. When delivered subdermally, it selectively targets adipose tissue, causing controlled lipolysis (fat liquefaction) while simultaneously providing hemostasis to minimize bruising.1
A retrospective analysis of 534 procedures by Reynaud et al. confirmed the 980nm diode laser as a safe and effective method for removing small volumes of fat with concurrent subdermal tissue contraction, achieving 80% patient satisfaction with rapid recovery.1
Primary Chromophore Targets
- Hemoglobin— Vascular coagulation & hemostasis
- Lipids— Selective fat cell disruption
- Water (moderate)— Tissue heating for contraction
Primary Chromophore Targets
- Water (high)— Deep dermal heating & remodeling
- Collagen— Thermal contraction & neocollagenesis
- Extracellular matrix— Structural tissue reorganization
1470nm Wavelength
EraLift Mode
The 1470nm wavelength has an exceptionally high affinity for water, making it ideal for dermal remodeling. When delivered subdermally, it causes controlled thermal damage to the dermal matrix, triggering an immediate collagen contraction followed by long-term neocollagenesis.4
Nilforoushzadeh et al. demonstrated a 48.75% increase in dermis density following 1470nm subdermal laser treatment for neck wrinkles, with significant reductions in wrinkle depth and area.2 A separate study on nasolabial folds showed a 43.75% increase in dermis density with 100% patient satisfaction.3
Dual-Wavelength Synergy
EraDefine: The Power of Both
When both wavelengths are delivered simultaneously, the 1470nm drives collagen contraction and skin tightening while the 980nm provides hemostasis and contributes to lipolysis.6 This synergistic approach addresses both laxity and volume in a single treatment session, offering comprehensive contour refinement.
Mechanism of Action
How Subdermal Laser Remodeling Works
Fiber Insertion
A thin optical fiber (400–800μm, selected by treatment area) is inserted subdermally through a micro-incision or cannula entry point, positioned within the target tissue layer. Fiber sizes: 400μm for periorbital, 600μm for face/neck, 800μm for body.
Energy Delivery
Controlled laser energy is delivered in a fan-like pattern. The physician selects wavelength mode based on anatomical target — fat, dermis, or both.
Tissue Response
Immediate collagen contraction occurs at the dermal level. Adipose tissue undergoes controlled lipolysis. Hemostasis minimizes bruising and downtime.5
Remodeling Phase
Over 3–6 months, neocollagenesis produces new collagen fibers, resulting in progressive skin tightening and improved tissue quality.4
Safety Profile
Favorable Safety with Proper Technique
Across all reviewed clinical studies, the procedure is consistently reported as safe. Most adverse events are mild and transient, including temporary edema, ecchymosis, and discomfort that resolve within days.57
Serious complications such as burns or nerve damage are rare and are almost always attributed to improper technique — specifically excessive energy delivery or inadequate thermal monitoring.8 The Elicit systematic review of 31 studies confirmed 80–93% patient satisfaction with a strong safety profile when proper protocols are followed.5
"Keeping skin surface temperature below 40–45°C is critical to avoiding complications."
