It has proven effective in treating Acne vulgaris, seasonal affective disorder, and for some people it has ameliorated delayed sleep phase syndrome. It has recently been shown effective in non-seasonal depression. Proponents claim demonstrable benefits for skin conditions such as psoriasis and, more controversially, a degree of “skin rejuvenation.”
