The function of a 560nm filter in Broadband Light (BBL) therapy is to isolate specific wavelengths of light that are optimally absorbed by hemoglobin and melanin. By refining the light spectrum, this filter ensures that energy is delivered precisely to the microvessels within the sarcoidosis lesion, initiating a process that destroys problematic tissue while sparing healthy skin.
Core Takeaway: The 560nm filter acts as a precision tool that enables selective photothermolysis. It directs light energy to heat and destroy the microscopic blood vessels fueling the sarcoidosis lesion, effectively reducing inflammation and redness without damaging the surrounding normal tissue.
The Mechanism of Selective Photothermolysis
Targeting Specific Chromophores
The 560nm filter is designed to capture wavelengths that interact specifically with "chromophores"—the light-absorbing parts of a molecule.
In cutaneous sarcoidosis, the primary targets are hemoglobin (found in blood) and melanin (skin pigment).
Energy Absorption and Heat Generation
When the filtered light hits these chromophores, the energy is absorbed and instantly converted into heat.
This targeted heating is the fundamental mechanism required to treat the lesion from the inside out.
Destruction of Microvessels
The heat generated by the absorption of light by hemoglobin specifically targets the microvessels within the lesion tissue.
By destroying these tiny blood vessels, the therapy cuts off the vascular support that contributes to the lesion's appearance and activity.
Therapeutic Impact on Cutaneous Sarcoidosis
Reducing the Inflammatory Response
Cutaneous sarcoidosis is an inflammatory condition.
By destroying the microvessels, BBL therapy significantly reduces the local inflammatory response associated with the disease.
Improving Lesion Appearance
The destruction of vascular structures directly addresses the redness and discoloration often seen in sarcoidosis lesions.
Minimizing Collateral Damage
A critical function of the 560nm filter is safety.
By ensuring the energy is "primarily absorbed" by the targets, the filter minimizes the risk of heat damage to the surrounding normal tissues that do not contain high concentrations of the target chromophores.
Understanding the Strategic Trade-offs
Precision vs. General Heating
The use of a filter represents a strategic trade-off between delivering raw power and achieving precision.
Without the filter, broad-spectrum light would heat the skin indiscriminately, potentially causing burns or adverse effects on healthy tissue.
The Balance of Absorption
The 560nm wavelength is selected because it sits at an optimal point for absorption by both hemoglobin and melanin.
This dual targeting allows the practitioner to address both vascularity (redness) and pigmentation issues simultaneously within the sarcoidosis lesion.
Making the Right Choice for Your Goal
When evaluating BBL therapy for cutaneous sarcoidosis, understanding the role of the filter helps set realistic expectations regarding treatment outcomes.
- If your primary focus is reducing visible redness: The 560nm filter is essential because it specifically targets hemoglobin to destroy the microvessels causing the discoloration.
- If your primary focus is safety and skin preservation: The filter is the key safety mechanism that prevents damage to the surrounding healthy skin by restricting energy absorption to the lesion itself.
The 560nm filter transforms raw light energy into a targeted therapeutic tool, balancing the destruction of inflammatory tissue with the preservation of healthy skin.
