Psoriasis Advance. 2011.
Many aspects must be taken into consideration when selecting a treatment modality for psoriasis. Frequency and method of dosing, length of therapy required, possible adverse effects and risks, and more must be kept in mind. Treating psoriasis with light therapy, proves to be a desirable option because of these considerations. Thrice weekly dosing for 12 weeks to achieve remission, accompanied by minimal side effects and risks in comparison to lengthier duration of therapy and even lengthier lists of adverse effects from other treatment modalities supports the use of phototherapy.
