“…Blue light can be used to treat acne [ 15 ], reduce sebaceous hyperplasia [ 16 ], and stimulate hair regrowth [ 17 ]. Our recent studies have shown the positive results of treating Port Wine Stains and telangiectasia with a 450 nm laser [ 18 ] and using it as a surgical tool instead of a CO 2 laser [ 19 ]. To our knowledge, a blue laser has not been tested for the treatment of lentigines.…”

This study tested a blue light source for the treatment of solar lentigines. A total of 14 patients with solar lentigines were treated with radiation from a novel, high-power 450 nm blue laser that was created for this project. The group contained eight patients with solar lentigines on the face, two patients with the lesions on the dorsal of the hands, and four patients with the lesions on the trunk and forearms. The best results (complete recovery) have been achieved for the lesions on the face and dorsal of the hands. The treatment of lesions on the trunk and forearms was not fully satisfying due to the occurrence of slight scarring. This study shows that, in some cases, the use of a blue laser may be an alternative to the use of longer wavelength sources.
