1. What is the Yonker YK-6000 portable UV device?

The Yonker YK-6000 is a portable Class II medical UVB phototherapy lamp designed for home use. It emits narrowband ultraviolet light (listed at 311 nm) and is intended to assist in managing skin conditions such as psoriasis and vitiligo.

2. Which skin conditions can this device help manage?

The device is intended for use as phototherapy support for conditions including psoriasis and vitiligo. It is also sometimes used adjunctively for certain eczema or herpes-related skin issues. Always consult a dermatologist to confirm whether phototherapy is appropriate for your condition.

3. What wavelength does the device use — 308nm or 311nm?

The specification for this model lists a 311 nm wavelength (narrowband UVB), which is commonly used in phototherapy. The product name also references 308 nm; if a specific 308 nm output is required for your treatment, verify the exact model/wavelength with the seller before purchase.

4. How do I position and use the lamp safely?

Follow the user manual and your clinician's instructions. The specified working distance for this unit is approximately 3 ± 0.5 cm from the skin. Treat clean, dry skin, protect eyes with approved goggles, and avoid directing the lamp at non-target areas. Begin with short exposure times as directed by a healthcare professional.

5. How often and how long should I use the device?

Treatment frequency and duration depend on your skin type and condition. Do not self-prescribe doses; start under medical guidance. Your dermatologist will recommend a safe starting exposure and a schedule based on response and tolerance.

6. Do I need a prescription to use this device at home?

Regulations vary by region. Many dermatologists recommend or require medical assessment before home phototherapy. Consult your healthcare provider and check local regulations; use only under clinician supervision if recommended.

7. What are the possible side effects or risks?

Short-term side effects may include redness, itching, dryness, or mild burns if overexposed. Long-term UV exposure can increase risks of photoaging and skin cancer. Use protective eyewear, follow dosing guidance, and have regular medical follow-up.

8. Who should not use this phototherapy lamp?

People with a history of photosensitivity disorders, certain skin cancers, or those taking photosensitizing medications should avoid or use it only under strict medical supervision. Pregnant or breastfeeding individuals should consult their healthcare provider first.

9. Is it safe to use topical creams with this device?

Some topical agents increase photosensitivity (for example, certain psoralens or other sensitizing medications). Only use topical treatments in combination with phototherapy when advised by your dermatologist and follow their instructions.

10. What protective measures are recommended during treatment?

Always wear protective UV goggles to shield the eyes, cover unaffected skin and mucous membranes, and avoid exposure to tattoos or areas with skin cancer or suspicious lesions. Follow clinician and manufacturer safety instructions.

11. What are the physical specifications and portability details?

The single package size is approximately 40 x 25 x 10 cm and the gross weight is about 2.0 kg, making the unit lightweight and portable for travel. Confirm power requirements and accessories with the seller before travel.

12. How should I clean and maintain the device?

Turn the device off and unplug it before cleaning. Wipe the exterior and lamp window gently with a soft, dry or slightly damp cloth. Do not immerse the unit in water or allow liquids into ventilation openings. Follow maintenance instructions in the user manual.

13. What certifications and warranty information does the device have?

The device is listed as a Class II medical instrument. Warranty length and additional certifications can vary by seller/region—verify CE/other regulatory markings and warranty terms with your supplier before purchase.

14. Are accessories like goggles or adapters included?

The product listing specifies a single selling unit but does not list included accessories. Check the seller’s product page or contact the vendor to confirm whether protective goggles, power adapters, or carrying cases are included.
