Please welcome our newest dermatologists, Dr. Cory Pettit and Dr. Dan Flood, who joined COSC this year!

Central Ohio Skin & Cancer offers several phototherapy treatments for the treatments of conditions such as psoriasis, vitiligo, atopic dermatitis, lichen planus, pruritus, polymorphous light eruption and early state mycosis fungoides.

Narrow-band UVB (NB-UVB)

NB-UVB is the most common form of phototherapy used to treat skin diseases. It uses the “narrowband” of 311-312 nm wavelength as this has been found to be the most beneficial component of natural sunlight to treat skin conditions. Compared to Broadband UVB (290-320 nm), NB-UVB exposure times are shorter but of higher intensity. The course of treatment is shorter. NB-UVB is more likely to clear the skin condition and longer periods of remission occur before it reappears. The patient stands in the middle of the NB-UVB booth undressed and a whole body treatment can be performed in seconds to minutes with coverage of certain body areas. Treatments are usually performed 3 times per week for 20-25 treatments on average to clear psoriasis.

Hand and Foot PUVA

Psoralen (P) is applied to the hands and feet and allowed to sit for a half hour. The hands and/or feet are then exposed to Ultraviolet A (UVA) light to treat psoriasis, eczema or vitiligo. Treatments are performed initially 3 times per week

Levulan/Blu-U Photodynamic Therapy (PDT)

For Treatment of Actinic Keratosis (AKs)

The Levulan solution is applied to the affected AK area 1-2 hours before the treatment and is absorbed by the AK cells where it is converted to a chemical that makes the cells extremely sensitive to the Blu-U light. When the AK cells are exposed to the Blu-U light for 16 minutes, a reaction occurs that destroys the AK cells.
