How does Personal Targeted Phototherapy™ (PTP) treatment with Levia® compare with other forms of UVB Phototherapy?
• The UVB light from most home phototherapy devices is within the same spectral band as the light emitted from Levia® (see UVB – Select FAQ). A major difference, however, is the method of light delivery. Panels and booths cannot precisely target the light where the psoriasis spot is located. A way to overcome this problem is to mask the adjacent uninvolved skin in order to protect it from unnecessary exposure to UVB light. Whole body phototherapy is paced by the level of light that is tolerated by uninvolved skin. Targeted phototherapy directs the light exactly where it is needed and the levels are adjusted based on the tolerance or the affected area. Generally, affected areas and thick plaque can tolerate more light. By adjusting the level of energy delivered Levia optimizes the dose based on the increasing tolerance of the affected area, and is not slowed down by the lower tolerance of uninvolved skin. Levia targets the UVB light directly to affected areas of skin and scalp. For area
