How 308nm UVB Light Therapy Works: 1. Increasing Melanin Production UVB increases tyrosinase and HMB-45 receptor expression on melanocytes,increasing melanin production, it's an excellent treatment option for vitiligo. 2. Suppressing DNA Synthesis UV Phototherapy works by suppressing DNA syn-thesis, which in turn reduces inflammation. UV light shuts down immune system cells in the skin. It can help in skin conditions that are caused by an overre-actionof the immune system,such as Psoriasis. 3. Induces T cell apoptosis UV light have an effect on the immune system. In par-ticular it can reduce the number of cells called T-cell lymphocytes in the skin. These cells are involved in the inflammatory response and are known to play an important part in eczema.
