I didn't think there was much, beyond the Viagra and Cialis ads that flood the prime-time airwaves my son will eventually view, in terms of prescription medication developed for entirely discretionary / non-life-threatening conditions.
but hey! - now there's Latisse - to help prevent the life-crushing malady of "hypotrichosis" - excuse me, i mean inadequate or not enough eyelashes.
aside from being born with a condition where your eyelashes are so short as to not serve their evolutionary function of filtering dust and other irritants from your eyes (and i'm not convinced that Brooke Shields' "before" example here fits that bill), is it really worth the possibility of "skin darkening, eye irritation, dryness of the eyes, and redness of the eyelids"?
to the credit of the makers of Latisse, there's no mention of possible explosive diarrhea or insanity / suicidal thoughts, but still it seems a bit of an annoying potential downside for a little bit of body fashion. aren't there eyeliners on the market that give the ladies' eyelashes an illusion of being longer without the cost of prescription copays or physical side effects?
bottom line: scientists spent a good amount of time and R&D money figuring out how to make eyelashes a little longer while the riddle of cancer continues on largely unsolved.
