Frequently Asked Questions

Phototherapy, also known as light therapy, is a medical treatment that involves exposing a person to specific wavelengths of light to treat various health conditions. Different types of light, such as ultraviolet (UV), visible, or infrared light, can be used for phototherapy, depending on the condition being treated. Phototherapy works by influencing biological processes in the body through light absorption. The light energy is absorbed by T-11 helper cells and tissues, which can lead to various therapeutic effects.

Narrowband UVB (ultraviolet B) phototherapy is a treatment that uses a specific, targeted range of UV light (311–313 nm) to help manage a variety of skin conditions.

It works by exposing the skin to controlled doses of UVB light, which can help:

• Slow excessive skin cell growth
• Reduce inflammation
• Support healing in affected areas

It is commonly used for conditions such as psoriasis, vitiligo, eczema, and other inflammatory skin disorders. Compared with broad-spectrum UVB, narrowband UVB is more targeted, often more effective, and associated with fewer side effects such as burning or skin damage.

Treatment is delivered in short, controlled sessions, with frequency and duration determined by a healthcare provider based on your condition and skin response. Consistent monitoring helps ensure safe, effective results over time.

Some topical products and medications can affect phototherapy results or increase skin sensitivity to UV light.

• Certain lotions may contain UV-blocking ingredients that reduce treatment effectiveness, similar to sunscreen
• Some products and medications can make the skin more sensitive to light (photosensitize), increasing the risk of reactions
• Ingredients to watch for include essential oils like lime, lemon, or orange, as well as coal tar, psoralens, and retinoids

Always review your current medications and skincare products with a healthcare provider to ensure they are compatible with phototherapy.

No—phototherapy and tanning beds both use light, but they are very different in purpose, safety, and how they work.

Phototherapy
Phototherapy is a medical treatment prescribed by a healthcare provider to treat skin conditions. It uses controlled doses of UV light—most commonly narrowband UVB (311 nm)—to target specific skin cells. Treatments are carefully monitored with precise dosing and timing to maximize benefits and minimize risks like skin damage. It is commonly used for conditions such as psoriasis, vitiligo, CTCL, and eczema.

Tanning Beds
Tanning beds are designed to darken the skin by increasing melanin production, primarily using UVA light. They are not medical treatments and are not regulated for therapeutic use. Overexposure to tanning beds is associated with significant risks, including premature skin aging and an increased risk of skin cancer. The World Health Organization (WHO) classifies tanning devices as Group 1 carcinogens, meaning they are known to cause cancer in humans.

In summary: Phototherapy is a controlled, medically supervised treatment for specific conditions, while tanning beds are cosmetic devices that carry serious health risks and should be avoided.

Phototherapy and tanning beds both involve exposing the skin to light, but they are used for different purposes and utilize different types of light.

Phototherapy and LED light therapy are related concepts, but not the same. LED light therapy is a specific type of phototherapy that uses light-emitting diodes to emit targeted wavelengths of light for cosmetic and dermatological purposes. Phototherapy, on the other hand, encompasses a broader range of treatments using various types of light to address a wide array of medical conditions beyond cosmetic concerns. Narrowband UV phototherapy uses UV light, such as UVB or UVA, and should be administered under medical supervision and is often used to treat skin conditions like psoriasis, vitiligo, eczema, and other health issues.

Yes, it’s possible to undergo certain types of phototherapy at home under the guidance and supervision of a healthcare professional with our in-home phototherapy devices available by prescription. It’s important to note that in-home phototherapy is not suitable for everyone, and the decision to undergo treatment at home should always be made in consultation with a medical professional. Self-administered phototherapy, such as utilizing a 3rd party or used device, without proper guidance can lead to ineffective treatment, adverse effects, or exacerbation of the underlying condition. Always prioritize your safety and follow your healthcare provider’s recommendations.

Yes. Some skincare products and medications can affect the safety or effectiveness of phototherapy.

Certain lotions contain UV-blocking ingredients similar to those found in sunscreen, which may reduce the benefits of treatment. Other products and medications can make your skin more sensitive to UV light, increasing the risk of skin reactions.

Use caution with products containing photosensitizing ingredients, including essential oils such as lime, lemon, or orange. Medications and treatments such as coal tar, psoralens, and retinoids can also increase sensitivity to UV exposure.

Before starting phototherapy, review all medications, topical treatments, and skincare products with your healthcare provider to ensure they are compatible with your treatment plan.
