What is phototherapy?
The term phototherapy is a form of treatment where fluorescent light bulbs are used to treat skin conditions. Natural sunlight has been known to be beneficial in certain skin disorders for thousands of years, and it is the ultraviolet part of the radiation produced by the sun that is used in phototherapy, in particular the ultraviolet A (UVA) and ultraviolet B (UVB) wavelengths of light.
What conditions is phototherapy used to treat?
To name a few, psoriasis and atopic eczema.
[UVB - psoriasis, atopic eczema, polymorphic light eruption, generalised itching, pityriasis lichenoides, cutaneous T cell lymphoma, lichen planus, vitiligo and other less common conditions.
PUVA - chronic plaque psoriasis (if UVB ineffective), vitiligo, polymorphic light eruption and cutaneous T-cell lymphoma.
PUVA is often used second line if UVB is ineffective.
PUVA is favoured over UVB for some indications, such as mycosis fungoides
beyond patch stage, adult pityriasis rubra pilaris, hand and foot eczema.]
