Kernal KN-5000C Kernel Excimer Laser 308nm Phototherapy System for Psoriasis and Vitiligo

High-Intensity Targeted 308nm Excimer Phototherapy for Professional Use

Available to beauty clinics and dermatology practices for prescribing to patients as a long-term at-home solution.

The KN-5000C is a professional 308nm excimer phototherapy system built around imported xenon chloride (XeCl) excimer light source technology. Designed for high-precision, targeted treatment of small to medium lesion areas, the KN-5000C delivers significantly higher irradiation intensity than conventional UVB or standard excimer devices, supporting shorter treatment cycles and fewer sessions.

Certification: ISO13485, FDA 510K Cleared, CE MDR

Indications

The KN-5000C is positioned for phototherapy workflows involving:

• Vitiligo
• Psoriasis
• Eczema
• Pityriasis rosea

Treatment protocols and suitability should be determined by the treating physician based on lesion size, location, and patient condition.

Light Source

XeCl Excimer Light — 308nm
The system uses the latest generation of imported xenon chloride gas light source, continuously emitting high-intensity single-frequency 308nm excimer light with a stable waveband and pure spot output — designed to maximize treatment efficiency per session.

Why Intensity Matters: Comparative Output

Greater illumination intensity translates directly to faster treatment effect and fewer required sessions compared to lower-intensity home-use or traditional excimer devices.

Key Features

High-Precision Targeted Treatment
Suitable for small to medium treatment areas, the system is built for high targeting accuracy, making it easier to reach and treat specific lesion sites directly.

Flexible Treatment Handle
A flexible treatment handle precisely controls the irradiation range, keeping light confined to the lesion and avoiding exposure to surrounding healthy skin.

Automatic MED (Minimal Erythema Dose) Testing
A built-in UV dosage scheme enables automatic six-spot skin phototoxicity testing, simplifying what is normally a complex process into an easy, patient-specific workflow for determining the appropriate treatment dose.

Six Interchangeable Shading Sheets
Six different sizes of shading sheets are included, allowing the treatment area to be adapted to lesions of different sizes for more precise, efficient application.

Dual Treatment Modes
Users can select between dose mode and time mode depending on treatment preference and protocol.

8" Full Touch Screen
An 8-inch TFT color touch screen with a user-friendly GUI is designed to make operation easier, safer, and more convenient to monitor during treatment.

Quick-Connect Treatment Handle
The treatment handle uses a quick-connection design, making light source replacement faster and more convenient for ongoing clinical use.

Frequently Asked Questions

How is the KN-5000C different from standard NB-UVB or home-use UV devices?
It delivers up to 50 mW/cm² of intensity — roughly 5–17x the output of home-use or standard NB-UVB lamps — supporting faster results and fewer treatment sessions for targeted lesions.

Is this suitable for whole-body treatment?
No — the KN-5000C is designed for small to medium, targeted lesion areas rather than whole-body phototherapy, which is better suited to a cabinet-style system.

What is MED testing and why does it matter?
MED (Minimal Erythema Dose) testing determines the correct UV dose for an individual patient's skin. The KN-5000C automates this with a built-in six-spot test, simplifying dose calibration before treatment begins.

How long does the light source last?
The light source is rated for 500+ hours of use before replacement is needed.

ONE (1) YEAR LIMITED DEPOT WARRANTY 

1. Warranty Provider and Term

This warranty is provided and administered strictly by the manufacturer of this particular product, not by Medaza, Inc. The manufacturer warrants to the original purchasing entity ("Buyer") — including hospitals, clinics, and other licensed medical institutions within the United States — that the hardware product sold shall be free from defects in materials and workmanship under normal clinical use for a period of one (1) year from the date of shipment. This warranty is provided in addition to, and does not affect, any rights the Buyer may hold under applicable state or federal law.

2. Depot-Only Return Procedure

Warranty service is strictly a depot-return process conducted directly by the manufacturer of this particular product.

• First Step (Intake): To initiate a warranty claim, the Buyer must not contact the manufacturer directly. The Buyer must first contact Medaza, Inc. by email at contactusa@medaza-platform.com.
• Delegation: Upon receipt of the email, Medaza, Inc. — acting in its capacity as distributor — will delegate and coordinate the direct connection between the manufacturer (or the manufacturer's designated U.S. Initial Importer, where applicable) and the Buyer, facilitating return logistics and securing the required Return Merchandise Authorization (RMA) number.
• Shipment: No shipments will be accepted by the manufacturer's facility without an active, authorized RMA number. The product must be securely packaged in its original packaging (or equivalent protective packaging), with all patient-identifying information removed or de-identified in accordance with the Health Insurance Portability and Accountability Act (HIPAA) and other applicable privacy laws prior to shipment, and shipped directly to the designated service facility of the manufacturer.

3. Allocation of Shipping Costs (Two-Way Shipping)

The Buyer assumes full financial responsibility for all shipping logistics, packaging, handling fees, customs/tariffs, and insurance transit costs associated with the warranty claim. This includes:

• Inbound Shipping: The cost to safely transport the product from the Buyer's facility to the designated service location of the manufacturer.
• Outbound Shipping: The cost to return the repaired or replaced product from the manufacturer's facility back to the Buyer's designated location within the United States.

4. Recall & Systemic Defect Exception

The shipping cost allocation in Section 3 shall be waived solely in the event that the returned product is officially determined by the manufacturer, its designated U.S. Initial Importer, Medaza, Inc., or the FDA to be subject to a Recall, Safety Alert, or a verified batch-wide Systemic Manufacturing Defect, in accordance with 21 CFR Part 806 (Medical Device Reporting: Corrections and Removals) and related FDA recall procedures. In such extraordinary circumstances, the manufacturer will cover standard two-way ground shipping costs.

5. Warranty Exclusions

This warranty does not cover:

• Disposable clinical consumables (including but not limited to needles, sutures, applicators, and single-use accessories) once packaging is opened.
• Damage caused by accident, abuse, liquid spills, improper sterilization or disinfection, neglect, patient misuse, or unauthorized modifications or repairs.
• Damage resulting from use outside the manufacturer's labeled indications, intended use, or instructions for use (IFU).
• Normal wear and tear, consumable component degradation (e.g., lamps, filters, probes), or cosmetic degradation that does not affect device function or safety.
• Any device on which the serial number, UDI (Unique Device Identifier), or product identification label has been removed, altered, or defaced.

6. Adverse Event Reporting

Nothing in this warranty limits or replaces the Buyer's independent obligation, as a healthcare institution or professional user, to report device malfunctions, serious injuries, or adverse events involving this product to the manufacturer, to the manufacturer's designated U.S. Initial Importer (where applicable), to Medaza, Inc. as distributor, and, where required under 21 CFR Part 803 (Medical Device Reporting), to the FDA (e.g., via MedWatch).
