The history of light therapy dates back more than 3000 years in India, where sunlight was used for therapeutic purposes and recorded in the sacred Hindu texts. However, the sunlight that reaches us is made up of two types of harmful rays: long wave ultraviolet A (UVA) and short wave ultraviolet B (UVB). Basically, UVA rays can age us and UVB rays can burn us. Overexposure to either can damage the skin.
