UVA1 Light Therapy at Johns Hopkins
Drs. Sewon Kang and Ronald Sweren are two of the physicians who oversee light therapy for patients in the Department's PUVA, Narrowband UVB, or new UVA1 units.

Phototherapy is the use of light to treat skin disorders.  The phototherapy unit emits specific wavelengths of light proven to benefit patients with various skin disorders. Types of phototherapy offered at Johns Hopkins are PUVA (Photochemotherapy), Narrowband UVB, and UVA1.  Please contact us to schedule a consultation or to refer a patient. 

PUVA (Photochemotherapy) and Narrowband UVB

PUVA phototherapy uses UVA rays in conjunction with an oral medication, psoralen, which sensitizes skin to emitted light.  Narrowband UVB phototherapy uses UVB light rays without the use of an oral medication. Some skin disorders that both PUVA and Narrowband UVB may be used to treat include:

  • Atopic dermatitis / Eczema
  • Psoriasis
  • Pruritus (itching)
  • Graft-versus-Host Disease (GVHD)
  • Vitiligo


Johns Hopkins is proud to be the first institution to offer stand-up UVA1 treatment on the East Coast.  Some diseases that UVA1 phototherapy may be used to treat include:

  • Atopic dermatitis
  • Morphea / Scleroderma
  • Scleredema
  • Nephrogenic Systemic Fibrosis (NSF)
  • Chronic Graft-versus-Host Disease (GVHD) with Scleroderma features
