Why Choose This 308nm Excimer Phototherapy Machine?

• 308nm Targeted Treatment

Delivers precise 308nm UVB energy directly to localized treatment areas, focusing treatment on affected skin while minimizing unnecessary exposure to surrounding healthy skin.

The targeted irradiation design allows professionals to provide more accurate phototherapy for localized lesions, making it suitable for areas such as the face, hands, elbows, knees and other small or irregular treatment regions.

Value for professionals:

1. More precise treatment positioning
2. Reduced exposure of unaffected skin
3. Suitable for customized treatment plans based on lesion size and location

• High Irradiation Intensity

With a 45 mW/cm² high-intensity 308nm output, the system supports efficient and controlled phototherapy sessions with stable energy delivery.

The high irradiation intensity helps shorten exposure time while maintaining accurate dose control, improving treatment efficiency for clinics with multiple patients.

Value for professionals:

1. More efficient treatment workflow
2. Consistent light output for reliable sessions

• Designed for Difficult Treatment Areas

The lightweight handheld applicator combined with six interchangeable treatment hoods provides flexible coverage for different lesion sizes and body locations.

The targeted design makes it easier to treat small, curved or hard-to-reach areas where conventional large-area phototherapy systems may be less convenient.

Value for professionals:

• Better access to complex body areas
• More comfortable operation during treatment
• One device supports various localized phototherapy applications

• Faster Repigmentation Response

For localized depigmentation conditions such as vitiligo, 308nm excimer phototherapy can deliver a concentrated UVB dose directly to the affected area, allowing higher treatment intensity compared with conventional full-body NB-UVB approaches.

• User-friendly Operation Design

The independent treatment handle provides flexible and precise operation, allowing professionals to easily target different treatment areas. With selectable time mode and dose mode, the system adapts to different clinical treatment protocols. The built-in timer ensures accurate session control, while the phototherapy record function helps clinics maintain organized treatment histories and improve patient management efficiency.

308nm Excimer vs. 311nm NB-UVB

	308nm Excimer Light	311nm NB-UVB
Treatment Style	Targeted phototherapy	Broader-area phototherapy
Best suited for	Localized areas	Larger treatment areas
Surrounding Skin Exposure	More localized	Broader exposure
Application	Handheld targeted treatment	Lamp/panel treatment
Repigmentation Response	May achieve earlier visible response in some localized cases	Effective but usually requires longer exposure areas

PS. Choose 308nm excimer for targeted localized phototherapy; consider larger NB-UVB systems when broader skin coverage is required.

How 308nm Excimer Phototherapy Works

308nm excimer phototherapy delivers targeted UVB radiation to selected skin areas. Unlike broad-area UVB lamps, the handheld applicator allows the treatment area to be precisely defined while limiting unnecessary exposure of surrounding skin.

In clinical phototherapy, 308nm UVB has been studied for localized dermatologic conditions including vitiligo and psoriasis. Treatment dose and frequency should be determined according to skin response and professional guidance.

Powerful 308nm Excimer Light Treatment System

Built-in MED Test

Supports More Controlled Initial Dose Selection

A built-in MED test program enhances treatment evaluation and efficacy assessment. There are 6 types of skin selection for your convenience to test the initial exposure, ensuring the safe, orderly and effective treatment from the beginning to the end of the entire treatment cycle. The MED testing program helps establish an appropriate starting exposure before treatment, supporting more controlled phototherapy planning.

For individual users, please do the MED test under the guidance of professionals or dermatologists before starting the initial treatment.

Flexible Dose-Based or Time-Based Treatment

There are two modes for your treatment choice, you may choose time mode or dose mode as per your own situation under the guidance of your dermatologist. Before starting each treatment, you can first select the dose mode to set the total dose, or select the time mode to set the total exposure time. When the set parameters are used up, it means that the treatment is over and the machine will automatically stop working. There is no need to worry about accidental excessive exposure, it saves trouble and worry, bringing you a comfortable and energy-saving irradiation experience.

Simplified Patient Treatment Management

For individual users, when the user uses the machine for the first time, after setting the treatment program, he/she can enter his/her fingerprint into the system, so that he/she can directly open the set treatment program and accept the treatment next time. 

For clinical use, the dermatologist can enter the patient’s fingerprint as well, making it easy for the dermatologist to arrange all patients’ cases and information. 

Precision Targeted Treatment with 6 Interchangeable Hoods

Unlike conventional broad-area UVB devices, the 308nm excimer phototherapy system uses interchangeable treatment hoods to focus light precisely on affected skin areas.

Six hood sizes are included to accommodate different lesion dimensions, helping clinicians select the most suitable treatment window for each patient. This targeted approach reduces unnecessary UV exposure to surrounding healthy skin while maximizing treatment efficiency on the affected area.

The ergonomic hood design improves positioning accuracy and makes it easier to treat small, scattered, or hard-to-reach lesions during daily clinical use.

Full Touching Screen

8” TFT touching screen with user friendly GUI design, smooth operation without lag, making the operation easier. High-definition display, good visual experience; a small screen accommodates many functions, making treatment more convenient. 

Professional UV Safety Protection

To support safe phototherapy operation, the device comes with anti-UV protective goggles as a standard accessory.

During 308nm UVB irradiation, protective eyewear helps minimize unnecessary UV exposure to the eyes of patients and operators. The included goggles make the system ready for safer treatment preparation in dermatology clinics, medical facilities and physician-guided home use.

A complete phototherapy system includes not only precise light delivery, but also essential safety protection for every treatment session.

Attention Tips for Using 308nm Excimer Light Phototherapy

• 308nm excimer light is suitable for patients of all ages from infants to the elderly. It can also be safely used for the treatment of special parts including eyelids, lips, external genitalia, and perianal areas.
• Patients with solar dermatitis, lupus erythematosus, malignant tumors, xeroderma pigmentosum, Bloom syndrome, dermatomyositis, pregnant women, and other patients who are not suitable for ultraviolet irradiation treatment, etc. are not suitable for this irradiation.
• Please remember to put on the anti-uv goggles before turn on the machine!
• Avoid skin trauma and friction, and patients should not wear tight clothes.
• Patients should wear sunscreen when going out and avoid strong sunlight after treatment, such as swimming at low-latitude beaches or traveling in high-altitude areas. Special attention should be paid to the fact that ultraviolet rays can damage the skin and induce and aggravate the condition.
• Avoid chemical stimulation. Patients should not dye their hair or paint their nails, and their hands should not often come into contact with irritating chemicals.
• Patients should eat a normal and balanced diet without any dietary restrictions. Try to reduce or avoid smoking and drinking, and take vitamin drugs.
