Phototherapy for Skin Disease
If you have a skin disorder that fails to respond to standard treatments, there's hope. Some inflammatory skin disorders can be treated effectively with phototherapy. At Cedars-Sinai, these treatments are individually tailored and performed in our phototherapy unit to provide maximum benefits.
What Is Phototherapy?
Phototherapy is a type of light therapy that mimics the effects of sunlight exposure. We use ultraviolet (UV) light from artificial sources to trigger biologic processes that reduce inflammation and prevent skin cells from growing too quickly. Regularly exposing the affected area to this type of light controls inflammation and helps clear the skin.
Your care may include different types of light therapy, such as:
- Narrowband UVB light, high-intensity light
- Psoralen UVA (PUVA), which uses a substance called psoralen to help you absorb UVA light
