The primary function of this dual-wavelength platform is to execute a sequential irradiation process that maximizes skin reconstruction outcomes. It utilizes a 10,600 nm ablative CO2 laser to physically create microscopic channels in the skin, followed immediately by a 1570 nm non-ablative fiber laser to thermally expand the zone of coagulation.
The integration of these two specific wavelengths allows practitioners to achieve deeper dermal remodeling and enhanced collagen stimulation, significantly improving efficacy without increasing the clinical risks typically associated with aggressive ablative procedures.
The Mechanics of Sequential Irradiation
The effectiveness of this platform lies in how the two distinct wavelengths interact with tissue in a specific order within a single session.
The Role of the 10,600 nm CO2 Laser
The 10,600 nm wavelength serves as the ablative component of the treatment.
Its primary job is to vaporize tissue to create microscopic ablative channels. These physical openings penetrate the epidermis and dermis, acting as the initial stimulus for the wound-healing response.
The Role of the 1570 nm Fiber Laser
The 1570 nm wavelength acts as the non-ablative component.
This laser follows the CO2 irradiation to deliver heat into the tissue surrounding the ablative channels. Its function is to expand the coagulation zone—the area of controlled thermal damage—without removing more tissue.
The Synergistic Effect
By combining these steps, the system treats a larger volume of tissue than a CO2 laser could safely do alone.
The 10,600 nm laser opens the door, and the 1570 nm laser delivers the deep thermal energy needed for remodeling.
Clinical Objectives and Outcomes
The goal of integrating these wavelengths is to solve the limitation of using a single laser source.
Deep Dermal Remodeling
Standard ablative lasers can only go so deep before the risk of scarring becomes unacceptable.
By adding the 1570 nm non-ablative energy, this platform extends the depth of remodeling. It targets the structural layers of the skin more effectively than superficial treatments.
Enhanced Collagen Stimulation
Collagen production is triggered by heat and injury.
Because the 1570 nm laser expands the coagulation zone, it subjects more fibroblasts (collagen-producing cells) to thermal stimulation. This results in a more robust neo-collagenesis response compared to narrow ablative channels alone.
Understanding the Safety Trade-off
In laser dermatology, increasing the volume of treated tissue usually correlates with higher risks, such as infection or scarring.
Managing Clinical Risk
The core innovation here is decoupling ablation from thermal damage.
Purely ablative lasers that remove large volumes of tissue carry high risks. This platform achieves high-volume treatment by keeping the physical ablation (10,600 nm) precise and using non-ablative heat (1570 nm) for the bulk of the work.
The Limit of Non-Ablative Energy
While safer, the 1570 nm wavelength alone cannot achieve the dramatic resurfacing results of an ablative laser.
It requires the 10,600 nm channels to break the skin barrier first. The trade-off is that this is a complex, multi-step biological interaction that requires precise calibration to ensure the thermal zone does not overlap excessively, which could lead to bulk heating issues.
Making the Right Choice for Your Goal
When evaluating skin reconstruction technologies, consider how this specific dual-wavelength approach aligns with your clinical targets.
- If your primary focus is Maximum Efficacy: This platform is ideal as it combines physical resurfacing with deep volumetric heating for superior remodeling.
- If your primary focus is Safety Profile: This approach is advantageous because it achieves deep tissue effects without the severe risks associated with aggressive, fully ablative deep resurfacing.
By leveraging sequential irradiation, you maximize the biological response while maintaining a controlled safety profile.
