They compare to wavelengths that cause pigmentation changes, which occurs only in exposed areas of skin. So it may be that results would be lacking if you are simply outside & normally clothed. It is still a significant finding: Intricacies of our metabolic processes do not seem extremely advanced, and this gives further clues about them. Although it does not appear to be something that would be a major contributor to weight loss. (wouldn't any screen addict have exceptionally thin faces?) Nonetheless, I'm sure there's some eager snake oil sales folks already working up marketing for the latest fad weight loss schemes.
