Phototherapy

Light therapy, also known as phototherapy, is the use of ultraviolet (UV) light for its healing effects. Phototherapy has been used worldwide for nearly a century to treat chronic skin conditions such as psoriasis, vitiligo and severe eczema.

While many treatments decrease the overall immune system, UV light can be used to decrease the local immune system in the skin. In conditions such as psoriasis, light therapy can also slow down the development of thick, scaly skin. UV light therapy is used in vitiligo for its additional ability to stimulate melanocytes, the skin’s pigment-producing cells.

This makes phototherapy a nice treatment option for just about anyone—especially those who don’t like creams, those wanting a natural treatment, a steroid-free treatment, and those wanting additional control using a combination of therapies. Phototherapy is also a good option to consider for children and women during pregnancy.
