Frequently Asked Questions

UVB phototherapy uses carefully controlled ultraviolet B light to help manage certain skin conditions. A healthcare professional can assess whether it is appropriate for you.

UVB light affects processes in the skin involved in inflammation and cell growth. Treatment response varies by condition, dose, and individual.

308nm excimer light is commonly used for targeted areas, while 311nm narrowband UVB is often used for wider coverage. Your treatment plan determines which is suitable.

Clinicians may use UVB phototherapy for conditions such as psoriasis, vitiligo, and some forms of eczema. Suitability depends on diagnosis and medical history.

UVB and UVA use different ultraviolet wavelengths and treatment protocols. Some UVA treatments also involve a photosensitizing medication; do not interchange treatment plans.

No. Medical UVB phototherapy uses selected wavelengths and controlled dosing. Tanning beds are not substitutes for prescribed phototherapy.

Results differ by condition and person and may require a series of sessions. Ask your clinician what progress to expect and when to review your treatment plan.

Start with the wavelength recommended by your clinician, the size of the treatment area, and the device specifications. Our team can explain model features but cannot prescribe treatment.

Luma Comb is a handheld narrowband UVB option, while Luma Flex and Luma Station are 308nm excimer options with different formats. Compare each product page for the latest specifications.

A targeted device may be more convenient for smaller localized areas. Check the treatment window and your clinician's wavelength recommendation before choosing.

Devices with a larger treatment window may cover wider areas more efficiently. Compare the stated exposure area and recommended treatment approach for each model.

Some devices and accessories are designed to help expose the scalp through hair. Check the model instructions and consult your clinician before treating the scalp.

Consider how much skin needs treatment, the shape of the area, handling comfort, and whether the device can deliver the prescribed dose.

Do not share a treatment schedule or dose. Each user needs an individual assessment and treatment plan; follow the manual for hygiene and any multi-user features.

Read the specific model manual before first use, follow a clinician-approved treatment plan, protect your eyes, and keep a record of sessions.

Frequency depends on your diagnosis, skin response, and prescribed protocol. Do not increase session frequency to speed up results.

Session length depends on irradiance, target dose, distance, and device settings. Use the instructions for your exact model and your clinician's plan.

UVB dose should be determined using an appropriate clinical protocol, which may include skin type or MED assessment. Do not guess a starting dose.

Yes, use the UV-protective eyewear specified for your device and treatment plan. Never look directly at an active UVB source.

Do not automatically double the next dose. Ask your clinician or follow the missed-session instructions in your treatment protocol.

Turn the device off and follow its manual for cleaning, storage, inspection, and servicing. Avoid cleaning products or procedures not approved for your model.

Home treatment can be appropriate for selected patients when the device is used correctly under medical guidance. UV exposure can still cause burns and other adverse effects.

Yes. Redness, irritation, and burns can occur, especially if the dose is too high. Follow your treatment plan and seek advice if you experience an unexpected reaction.

Certain medical histories, photosensitivity conditions, and medications can make UV treatment unsuitable. A clinician should review your circumstances before treatment.

Some areas require special precautions or may be excluded from treatment. Do not treat sensitive areas without explicit guidance and appropriate shielding.

Some topical products can change skin sensitivity to light. Check with your clinician before combining UVB with prescription or over-the-counter treatments.

Stop and seek medical advice if you develop significant pain, blistering, severe redness, or another concerning reaction. Seek urgent care for serious symptoms.
