What Is Phototherapy?

Phototherapy is the use of light to treat psoriasis, vitiligo, and other photoresponsive skin disorders. During treatments, the skin is exposed to a special type of light emitted by a medical device commonly referred to as a phototherapy unit.

These units range from hand-held and table-top devices for spot treatment of small areas to cabinet or “walk-in” units for patients requiring full-body treatment. Phototherapy can be administered in one’s home or a patient can be given treatments in their physician’s clinic.

Why Choose Daavlin Phototherapy?


Narrow Band UVB phototherapy is considered a first-line treatment for many conditions such as psoriasis, vitiligo and eczema, is safe enough for pregnant women and children to use, and has none of the serious side effects associated with competing biological drug therapies. And, Daavlin devices utilize our patented ClearLink Control System – a proprietary control system that consistently monitors the patient’s treatments and ensures accuracy and safety for every treatment.


Phototherapy leads other treatments in both effectiveness and speed of clearance. Narrowband UVB and PUVA (Psoralen + UVA) are safe, work extremely well, and are twice as fast at clearing patients with moderate to severe psoriasis. 

Clearance Rates
  • PUVA (Psoralen + UVA): 90%1
  • Daavlin Narrowband UVB: 82%6
  • Remicade® (Infliximab): 80%5
  • Humira® (Adalimumab): 62%4
  • Enbrel® (Etanercept): 47%-49%3

Whether you’re in a need of a full-body treatment, or a small, handheld unit for spot or scalp treatments, Daavlin has you covered. Our product lineup contains devices that meet the needs of a wide variety of scenarios and our build quality is second to none.
