UVB DERMATOLOGIC PHOTOTHERAPY
ARTIFICIAL SUNLIGHT
NARROWBAND UV B LIGHT
WAVELENGTH 311-320nm
Has revolutionarised treatment of several
dermatoses over the past 2 decades. There is
no more need for patients to travel abroad.
First type was UVA, which required
administering of oral psoralens, carrying
several risks. UVB is the current generation

Psoriasis
Vitiligo
Severe Atopic Dermatitis
Cutaneous T cell Lymphoma (Mycosis Fungoides)
Alopecia Areata
Very helpful alternative in treating HIV patients
with dermatoses that would ordinarily have
required immunosuppressants.
How Does it work?
• The mechanism of action of UVB on various skin
diseases is probably related to the suppression of
major components of cell-mediated immune function.
• UVB radiation is absorbed by DNA and urocanic acid.
• It alters antigen-presenting cell activity.
• In psoriasis, it lowers peripheral natural killer cell
activity, lymphocyte proliferation and
immunoregulatory cytokine production by Th1 (IL-2,
IFN-alpha) and Th2 (IL-10) T-cell populations.
• Has a high safety profile , can even be used in
pregnancy.
Success rates and average number of
sessions
• Psoriasis minimum 24 sessions (3 per week)
and 1 per week for maintenance
• Vitiligo over 150 sessions (2 per week)
• Mycosis Fungoides complete clearance 24
sessions
• Other dermatoses range from 12-48 sessions.
• We have machines for all sizes and areas, from
spot parts to whole body.
Vitiligo
• UVB Phototherapy has helped several of our
patients to regain colour. It is a major
psychologically debilitating disease prone to
extreme stigma. We provide psychosocial
support, in combination with UVB, Oral and
topical treatments.
• Repigmentation of more than 80% in all cases.
• Hands and feet are always the hardest to recover
but I perform Melanocyte punch graft transplants
and CO2 fractional laser for those parts, which
have a good outcome.
