Lasers & Light >> Targeted Phototherapy

Phototherapy was developed for the first time in the 20th century and since then it has been getting increasingly popular as a treatment option for Psoriasis, Vitiligo, Eczema, and other skin conditions. Phototherapy (also called Light therapy) treats skin disorders using different wavelengths of light- predominantly Ultraviolet (UV) light and Blue light. After careful evaluation of the patientís skin condition and his other medical history, Phototherapy may be prescribed for the patient. Unprotected and unregulated exposure must be avoided in order to avoid any complications. Ultraviolet A (UVA) and Ultraviolet B (UVB) are the two types of ultraviolet light that are used for the treatment.

A specific wavelength of ultraviolet (UV) radiation is used in the procedure and this varies for different conditions. It can be used alone or in combination with other medications applied directly to the skin or taken internally. Patients typically receive a series of exposures to the light about 2 -3 times per week for a period of 4- 8 months to bring their symptoms into check. The exact duration of treatment varies from case to case and can be decided after initial evaluation. They may also receive periodic maintenance treatments to prevent recurrence of their condition.

Targeted Phototherapy is a safe mode of treatment. Excessive exposure to Ultraviolet light is associated with skin ageing and hence it should be avoided. Targeted phototherapy may be compared to a reaction that occurs after excess exposure to sunlight but the major difference here is that sun tanning would affect the entire body but in targeted phototherapy, only the affected parts of the body are exposed to the Ultraviolet light. the normal skin remains unaffected whatsoever.

Advantages of targeted phototherapy:

  • It is a safe procedure

  • Absolutely painless

  • No downtime required: Patient can get to his work immediately after the treatment and does no require to take rest on account of the procedure

  • Treatment takes only a few seconds of exposure and the entire sitting takes about 10- 15 minutes only.

  • Prevents from the side-effects of conventional phototherapy (tanning of the rest of the body)
