Discover the Power of Phototherapy

Unlock the potential of phototherapy in dermatological treatment with NatBio Phototherapy.

What is Phototherapy?

Phototherapy is a prescribed medical treatment that uses specific wavelengths of light shone directly on affected areas of skin for conditions such as psoriasis, atopic dermatitis, vitiligo, and more. This light occurs naturally as a component of sunlight and is part of the ultraviolet light spectrum, most often UVA, UVB or Narrowband UVB. Your healthcare provider may offer treatments at a clinic or by prescribing a home phototherapy device. 

Types of Phototherapy

Phototherapy is available in various wave lengths; the three most notable are UVA, UVB, and NBUVB. While each has their respective applications, Narrow Band UVB (NBUVB) has become the preferred choice for home and clinical treatments due to its efficacy and minimal risk of side effects.  

Here are some common types of phototherapy:

Narrowband UVB (NBUVB)

Narrowband UVB therapy is a more targeted form of UVB phototherapy that uses a specific narrow range of UVB wavelengths. It has been found to be more effective and have fewer side effects compared to broad-spectrum UVB phototherapy. Narrowband UVB is commonly used for treating conditions such as psoriasis, eczema, and vitiligo. 

UVB Phototherapy

UVB (Ultraviolet B) phototherapy involves exposing the skin to UVB light, which helps reduce inflammation and slow down the rapid growth of skin cells. It is commonly used to treat conditions such as psoriasis, eczema, vitiligo, and certain types of dermatitis. 

PUVA Phototherapy

PUVA (Psoralen plus Ultraviolet A) therapy combines the use of a light-sensitizing medication called psoralen with exposure to UVA (Ultraviolet A) light. This combination enhances the effects of phototherapy and is often used to treat psoriasis, eczema, vitiligo, and certain types of skin lymphoma. 

Each type of phototherapy has its indications, benefits, and potential side effects. The choice of phototherapy modality depends on factors such as the specific condition being treated, the patient’s skin type, medical history, and treatment goals. It’s essential to consult with a qualified healthcare provider to determine the most appropriate phototherapy approach for individual patients. 

How Does Phototherapy Work?

During phototherapy sessions, the skin is exposed to specialized light emitted by medical-grade phototherapy units. These units vary in size, from handheld devices designed for localized treatment to larger, walk-in units catering to full-body needs. The ultraviolet (UV) light emitted by the medical lamps triggers cellular changes within the skin, prompting normalization of cell behavior in most patients. This normalization process often leads to a reduction or complete alleviation of skin disease symptoms. 

Initially, patients may undergo multiple treatments in quick succession to initiate skin improvement. As the skin responds positively and shows signs of enhancement, transitioning to a weekly maintenance treatment schedule may suffice to sustain the progress achieved. 

How Do I Order a Home Phototherapy Device?

Home phototherapy products are FDA-cleared medical devices requiring a prescription. Your healthcare provider needs to submit a prescription for a home phototherapy device and one of our team members will follow up with you to complete the purchase. Ask your healthcare provider if phototherapy is right for you. 

Decades of Proven Efficacy

Phototherapy boasts impressive efficacy data, with clinical trials showcasing remarkable outcomes for conditions like psoriasis, atopic dermatitis, vitiligo, and more. 

Recent clinical trials show 89.1% of guttate psoriasis and 64.8% of plaque psoriasis patients achieved a PASI 90 clearance in less than 7 weeks (over 20 sessions) – making phototherapy an ideal choice for many patients.

Phototherapy has demonstrated effectiveness in treating psoriasis, atopic dermatitis, vitiligo, and other photoresponsive conditions.

Unmatched Safety Record 

Phototherapy is one of the safest treatment options because it has fewer side effects than other treatments. Narrowband UVB therapy boasts an exceptional safety profile, making it suitable for children1, pregnant women2, the elderly3, and individuals with compromised immune systems.4 

Furthermore, research indicates that Narrowband UVB monotherapy is not significantly linked to the development of malignant melanoma, squamous cell carcinoma, or basal cell carcinoma.

“As a 45 year psoriasis sufferer, I was hopeful, yet skeptical. […] For the first time since I can remember, my skin is 100% clear. Treatment took approximately 2 months. […] I could not be happier with the product, the customer service and the results. It has literally changed my life.” 

“Before trying light therapy, my psoriasis had spread to forearms, elbows, legs, knees, and back despite regular applications of steroidal cream. My dermatologist suggested I try light therapy, and it seemed miraculous. After a few months of therapy at the doctor’s office, she suggested I get a home unit. […] So, high praise to my doctor, my insurance company who paid for a good bit of it and to Heather and [NatBio]. Time saved and clear skin. I’m delighted.” 

“After driving just over an hour each way to the doctor’s office to be treated with light therapy, I was finally approved to get my own machine. […] They made this complicated process of working with insurance companies an easy step by step process and it was always just a quick phone call away to answer my questions.”
